This is printed on the label attached to the back of the SAU-1900E on a label above a bar code (see figure below). An ideal time to record the serial number of your SAU-1900E would be when installing the SAU-1900E for the first time. Record the serial number in the back of this guide, and store this guide (along with your sales receipt) in a safe place separate from the SAU-1900E for future reference. 4 SECURITY If your SAU-1900E is ever lost or stolen you must report it to your network operator or service provider as soon as possible so that they can prevent your SAU-1900E from unauthorized use. This is important, as you may be liable for the cost of unauthorized calls until your SAU-1900E is reported lost or stolen. The network operator or service provider will need the serial number of your SAU-1900E in order to prevent it from unauthorized use. SAFETY Personal Safety Your SAU-1900E is basically a radio transmitter and receiver. When it is powered (either from the AC power supply or from the internal battery) it receives and transmits radio frequency (RF) energy and the system handling your calls controls its power level. It may transmit RF energy even when you are not actively placing a call in response to data sent by the service provider or in response to incoming calls. The design of the SAU-1900E complies with national safety guidelines with respect to human exposure and RF energy. However, you can choose to limit RF exposure even further by locating the SAU-1900E in a room, or closet, remote from the areas where your telephones are located. Furthermore, your SAU-1900E internally uses voltages/currents that could pose possible electric shock hazards, which could result in bodily injury. For your safety, do not attempt to open the SAU-1900E for any purpose other than replacing the battery

(refer to Battery Installation and Battery Removal) or determining the serial number of your SAU-1900E (refer to SERIAL NUMBER). The SAU-1900E enclosure has several slots and openings that are provided to protect it from overheating by providing adequate ventilation. In order for adequate ventilation to be provided, these slots and openings must never be covered or blocked. To prevent blocking these slots and openings, do not place the SAU-1900E on a bed, sofa, rug, or other similar surface, nor place anything on the SAU-1900E. Furthermore, do not push any object through these slots and openings as the object may touch dangerous voltage points or cause damage to the SAU-1900E, which could result in risk of fire or electrical shock. Finally, you need to unplug the SAU-1900E from the wall outlet and remove the internal battery, and contact your service provider or dealer for service of the SAU-1900E whenever one or more of the following has occurred:

1. When the AC power supply cords (either the cord that plugs into the SAU-1900E or the cord that plugs into a wall outlet) is damaged or frayed. 5 2. If liquid has been spilled into the SAU-1900E. 3. If the SAU-1900E has been exposed to water or rain. 4. If the SAU-1900E has experienced a severe, physical shock and the cabinet has been damaged. these instructions. 5. If the SAU-1900E exhibits a distinct change in performance that is not documented in 6. If the SAU-1900E does not operate normally according to these instructions, and the troubleshooting guide has not solved the problem. Do not attempt to service the SAU-1900E yourself, as this could result in risk of fire or personal injury. Dangerous Operating Environments IT IS RARE, BUT YOUR SAU-1900E OR ATTACHED PHONES AND ACCESSORIES COULD GENERATE SPARKS. THEREFORE, YOU SHOULD NOT LOCATE THE SAU-1900E IN AN AREA WITH A POTENTIALLY EXPLOSIVE ATMOSPHERE SINCE ANY SPARK COULD CAUSE AN EXPLOSION OR A FIRE RESULTING IN BODILY INJURY, OR EVEN DEATH. DO NOT STORE FLAMMABLE GAS, FLAMMABLE LIQUID, OR EXPLOSIVES CLOSE TO THE SAU-1900E. CONSTRUCTION CREWS OFTEN USE REMOTE-CONTROL RF DEVICES TO SET OFF EXPLOSIVES, SO DO NOT USE THE SAU-1900E IN AREAS WHERE BLASTING OPERATIONS ARE IN PROGRESS. TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THE SAU-

1900E TO RAIN OR ANY TYPE OF MOISTURE. 6 SAU-1900E INSTALLATION AND CONNECTION The SAU-1900E is designed to provide telephone-like service in areas for which normal wire line telephone service is not available or where the installation of additional telephone wire lines are not considered practical. Existing Telephone Service The SAU-1900E is intended to provide voice communications using regular, wire-line telephones without a wire-line service provider. It can also be used to provide additional lines in a house or business that already have wire-line service. However, the SAU-1900E cannot be tied into lines that already have existing wire-line or wireless telephone service. If the SAU-1900E is tied into these existing telephone lines, it will disrupt the SAU-1900Es capability of providing telephone service as well as disrupting the other telephone service. To test for an existing telephone service, plug a telephone into a wall jack in the house or business that you want to use the SAU-1900E. Follow the telephones instructions for placing a call, listening for a dial tone. If no dial tone is heard while trying to place a call, the SAU-1900E can be used. If a dial tone is heard, you already have some type of telephone service. Contact your service provider or dealer for instructions on what you should do in this situation. 7 Before installing the SAU-1900E, you need to install the battery into the SAU-

Battery Installation 1900E. 1. Insure that nothing is connected to the SAU-1900E. 2. Place a soft cloth on a flat work surface, such as a table. 3. Turn the SAU-1900E upside down onto a soft cloth and orient the SAU-1900E such that the three semi-circular/ridged cover release latches are toward you. 4. Remove the battery cover by depressing the semi-circular/ridged cover release latches and pushing the cover away from you. It should move toward the edge opposite you. Slide the cover completely out. 5. Turn or rotate the battery so that the silver terminals on the battery will align with the battery terminals located in the battery compartment. 6. Then insert the end of the battery closest to the terminals into the compartment, while also pulling gently on the battery strap (so that it will not be bunched up on the side of the battery). Press the battery into the compartment so it fits flush with the bottom of the housing. 7. Slide the battery cover in place (making sure that the strap lays flat on the battery) and make sure the latches lock into place. 8 Battery Charging The SAU-1900E has a built-in battery charger. It will automatically restore a fully discharged battery to nearly full charge within 24 hours of AC power being restored or applied. No external charger is necessary. CAUTION:

1. Avoid battery terminal short circuits (in other words, DO NOT let anything metal touch the two silver terminals on the battery at the same time). A fully charged battery can supply a very large current (more than 100 amps) which create a large amount of heat resulting in burns, smoke, or even fire. 2. DO NOT expose the battery to open flame. 3. DO NOT disassemble the battery. The batteries contain dilute sulfuric acid, which could damage eyes, skin or clothing and result in loss of eyesight or burns. 4. The battery contains lead and should be recycled or disposed of properly. Contact your service provider or dealer for details. 5. Only use approved batteries (YUASA OR YUASA-EXIDE Model NP2-12). Using other batteries will invalidate your warranty and may cause damage or injury as well. 9 Where to Install the SAU-1900E Also before installing the SAU-1900E, you need to determine where you want to install it. The SAU-1900E can be used on a flat horizontal surface, such as a desktop, table, etc. It can also be mounted on a wall. However, you should consider the following in determining where to install your SAU-1900E:

1. Do not place the SAU-1900E on an unstable cart, table, stand, etc. The SAU-1900E 2. Place the SAU-1900E near an AC electrical outlet, or wherever AC power is may fall and be damaged. available. 3. If you wish to use the SAU-1900E to drive your house or business telephone lines, place the SAU-1900E by a modular telephone wall jack that is connected to other modular telephone jacks within your house or business. 4. Do not place the SAU-1900E by anything that generates a great amount of heat, such as radiators, baseboard heaters, portable heaters, space heaters, ovens, fireplaces, etc. Placement of the SAU-1900E by these locations could possibly damage the exterior enclosure and effect the performance of the SAU-1900E. 5. Do not place the SAU-1900E near liquids, for example near sinks, kitchen counter-

tops, kitchen tables, bathtubs, swimming pools, in wet basements, etc. 6. Do not place the SAU-1900E in direct sunlight, such as by a window. Direct sunlight can cause the exterior finish to fade, and possibly cause the SAU-1900E to malfunction. 7. Do not place the SAU-1900E where the temperature will be below -15C (+5F) or above +50C (+122F). Temperatures beyond these ranges could possibly damage the SAU-1900E. 8. It is recommended not to place the SAU-1900E by a television set. Although every effort has been made for the SAU-1900E to not cause interference on a television, interference is still possible. 9. Use of cordless telephones with the SAU-1900E is permissible. However, you may want to keep the cordless telephone base and handset away from the SAU-1900E, as they may generate interference toward each other. 10. Computers can some times cause interference to the SAU-1900E. If the sound quality of your SAU-1900E degrades when switching on a computer, move the SAU-1900E further away from the computer (i.e. case, monitor, etc.). You may also want to plug the SAU-1900Es AC power supply into another outlet that is different from the computer. 11. Microwave ovens can sometimes generate interference to the SAU-1900E. If the sound quality of your SAU-1900E degrades when switching on a microwave oven, move the SAU-1900E further away from the oven. You may also want to plug the SAU-1900Es AC power supply into another outlet that is different from the oven. 12. If possible, try to place the SAU-1900E in the highest place that is practical and convenient. Do not place the SAU-1900E in a basement, if possible. 13. If you use any type of radio transmitters, such as citizen band radios, amateur radio, etc., it is recommended not to place the SAU-1900E by these radios or their antennas. 10 You may also want to plug the SAU-1900Es AC power supply into another outlet that is different from the radio transmitter. Modular Jack Requirements The SAU-1900E uses two RJ-11 type modular jacks (RJ-11 jack, shown below). These types of jacks are very convenient for connecting and disconnecting phones to your SAU-1900E, and connecting the SAU-1900E to an existing telephone network in your house or business. However, it is possible that where the SAU-1900E is to be used, another type of jack or even bare wire connections could be used instead. If this is the case, please contact the dealer where you purchased your SAU-1900E or your local service company for the appropriate adapters and instructions for their use. Desktop Installation Installing your SAU-1900E on a desktop is very easy. the SAU-1900E on any flat, horizontal, stable surface, such as a desktop or table. Then proceed to the section entitled connecting the SAU-1900E to Your Telephone(s). Simply place 11 Before installing the SAU-1900E on a wall, make sure that you have already Wall-Mount Installation installed the battery (refer to Battery Installation). For the SAU-1900E to be mounted on a wall, a telephone wall plate must already be installed (it is not included with the SAU-1900E). If you do not have a wall plate, and wish to mount your SAU-1900E on the wall, you will need to contact a general contractor to run the telephone wire and install the wall plate. Note: The SAU-1900E is heavier than most telephones. It is highly recommended that the above-mentioned wall plate be secured to the wall with anchor bolts, or other such means of making an extremely secure attachment of the wall plate to the wall. 1. Place a soft cloth on a flat surface, such as a table. 2. Place the SAU-1900E upside down on the cloth, such that the grills on the front of the For this installation, you will need a small, Phillips head screwdriver. SAU-1900E are facing you. 3. Take the wall-mounting bracket in hand. On one end of the bracket you have a flat surface with two small holes. This is the bottom of the bracket. On the other end you will see two small, rectangular prongs. This is the top of the bracket. Place these prongs into the top of the battery cover into the prong recesses, and let the other end of the bracket touch the bottom portion of the SAU-1900E. 4. Line the holes in the bottom part of the bracket with the holes in the SAU-1900E. 12 5. Using the screws that came with the SAU-1900E, place the screws into holes on the SAU-1900E through the holes in the bracket, and screw in the screws until the bracket is secure to the SAU-1900E. Note: Do not use any other screws other than what is included in your package. If you lose the screws, however, you may use two M4, self-tapping Phillips head screws of lengths between 5-8mm, but absolutely no longer than 8mm. 6. Taking the SAU-1900E bracket assembly in hand, insert the supplied short telephone cable through the small opening in the top of the bracket (between the prongs). Then, pull the telephone cable through the rectangular opening in the middle of the bracket. 7. Plug the end of the telephone cable that is now placed in the middle opening of the bracket into the wall plate. 8. Gently pulling up on the free end of the telephone cable, take up the slack of the cable, and slip the mounting holes of the bracket over the wall plate posts. 9. Slide the SAU-1900E firmly into place by pushing gently down (you will feel the SAU-1900E stop moving when it is locked into position). 10. Insert the free end of the telephone cable into one of the RJ-11 jacks on the top of the SAU-1900E. 13 Connecting the SAU-1900E to Your Telephone(s) The SAU-1900E may be connected to up to 4 Ringer Equivalency Number (REN) loads. The actual number of telephones that may be connected, however, depends upon the load each telephone provides. Telephone manufacturers are required by FCC regulations to stamp the value of the telephone load on the telephone themselves (usually the bottom) and these numbers usually appear as follows: REN: 1.0B or REN: 0.3A. It may also appear as RINGER EQUIVALENCE: 1.0A. You can ignore the A or B designations and only count the actual number values shown. Make sure that after adding up the REN's on all the phones, the count does not exceed 4.0. To connect the SAU-1900E in a business, or residence, is relatively easy. The following diagram shows a typical installation for two phones:

1. Determine the location where the SAU-1900E will be installed (see Where to Install the SAU-1900E). 2. Install the SAU-1900E (see Desktop Installation or Wall-Mount Installation). 3. Verify that the included antenna on the SAU-1900E is pointing up (vertically). If you are using an external antenna, connect the antenna connector to the SAU-1900E. 4. Connect the AC power supply adapter plug into the POWER jack on the back of the SAU-1900E, then plug the AC power supply into an AC Wall Outlet. LLLL! Warning: Use only the AC power supply that came with the SAU-1900E. Use of any other AC power supply could damage the SAU-1900E and void your warranty. LLLL! Warning: Make sure that the AC power supply voltage input of the power supply provided with your SAU-1900E matches the AC voltage in your house or business. If you are not sure, contact a qualified electrician. LLLL! Warning: Do not overload electrical wall outlets and electrical extension cords as this can result in the risk of fire or electrical shock. LLLL! Warning: Place the AC power supply cord where it will not be abused by people walking on it, pets chewing on it, etc. 5. Using a standard RJ-11 modular jack connector connect the SAU-1900E to a telephone or modular wall jack using common two-wire or four-wire flat telephone cable. (This will have already been done in the wall-mount installation). 14 The longest length of cabling for which the SAU-1900E has been designed is 1000 feet (305 meters). This should be sufficient for most installations. However, if your wiring is longer than 1000 feet, you may experience some audio problems with your telephone(s). Note: Do not allow anything to rest on telephone cords attached to the SAU-1900E. Do not locate the cord in a pathway or in a location where it is easily accessible to pets or small children, etc. 6. After installing the SAU-1900E, follow the instructions of one of the attached telephones to place a call, but do not dial a number. If you hear a dial tone within a few minutes of power-up, the SAU-1900E is properly connected and has detected the local network service provider. You may begin making and receiving telephone calls. 7. If you hear a BEEP - BEEP - BEEP -. Etc. the SAU-1900E has also been connected properly, but has not located a network service provider. Adjust the antenna and/or move the SAU-1900E to try to find an area of maximum RF reception. If you are still unable to receive a dial tone you should contact your service provider for assistance. 8. If you dont hear any sounds coming from the telephone, follow the telephones instructions for placing a call, and listen to the receiver while pressing some of the number keys on the telephone. If you do not hear any tones coming from the telephone speaker the problem could be a faulty cable or connector, or the SAU-

15 1900E may not be powered (dead or missing battery and no power from the AC/DC adapter). If all of these items have been checked and you still have no tones coming from the telephone you should return it to your service provider for service and/or assistance. SAU-1900E OPERATION LED Indicators Your SAU-1900E has three LED's (light emitting diodes) to let you know the status of your SAU-1900E unit. They are:

SIGNAL: This LED is an indicator of the received signal strength from a cellular base station that communicates with your SAU-1900E. It has three possible states:

1. When the SIGNAL LED is constantly lit your SAU-1900E and the cellular base station should have no difficulties communicating with each other. 2. When the SIGNAL LED is blinking, this means that communication between the SAU-1900E and the cellular base station is working, but marginal. This means that you should still be able to place and receive calls, but could possibly experience occasional dropouts in your conversation and even occasional dropped calls. (If you are using the included antenna, and experience this condition frequently, you may want to talk to your service provider about getting an externally mounted antenna to improve your reception.) 3. When the SIGNAL LED is not lit, this means that your SAU-1900E is not communicating with the cellular base station. This means that you will not be able to place a call or receive a call on your SAU-1900E. AC/BATTERY: This LED is an indicator of the power source being presently used by the SAU-1900E. It has three possible states:

1. A constantly lit AC/BATTERY LED indicates that AC power is being used to power the SAU-1900E. 2. When the AC/BATTERY LED is blinking, this indicates that no AC power is present, and the internal battery is powering the SAU-1900E. 3. When the AC/BATTERY LED is off, this indicates that the SAU-1900E is not powered (i.e. no AC power is provided, and either the internal battery has been completely discharged or is not installed). In this condition, the SAU-1900E will not be able to provide any telephone service. 16 DISRUPTION: This LED is an indicator of a malfunction of the SAU-1900E. It has two possible states:

1. When the DISRUPTION LED is lit, the SAU-1900E has definitely experienced a malfunction. Service is required for the SAU-1900E. Call your dealer for instructions on returning the SAU-1900E. You will receive a RMA (Return Merchandise Authorization) number. Send the SAU-1900E to your dealer with the RMA number on it at the address the dealer specifies. Please send the SAU-

1900E for repair in the original carton and packing material. If your original carton and packing material is not available, ask your dealer for instructions on how to pack your SAU-1900E so that damage will not occur during shipment. When the DISRUPTION LED is not lit, one of three things is true:

a) The SAU-1900E is working properly and is being powered by either AC power or the battery. AC power or the battery does not power the SAU-1900E. The SAU-

1900E cannot operate without some type of electrical power. AC power or the battery is powering the SAU-1900E, but the SAU-1900E is still not working properly. The disruption LED can indicate most, but not all problems that could occur with the SAU-1900E. b) c) 2. Making Calls Making calls on a telephone connected to the SAU-1900E is nearly as simple as placing a call on a standard wire-line service. Simply follow the telephones instructions for placing a call and press the keys for the number you wish to call. Once you have entered all the digits, press the <#> key to send the dialed number to the service provider. At this point operation is identical to a wire-line phone. Note: In order for a telephone to be used to place calls with the SAU-1900E, the telephone must be a touch-tone phone only or a phone that is switchable between TONE and PULSE(ROTARY) dial. On the phones that are switchable between TONE and PULSE(ROTARY) the phone must be set to TONE to place a call. A PULSE(ROTARY) phone can be used to receive calls; However, you will not be able to use any advanced features such as CALL FORWARDING, 3-WAY CALLING, etc., or any other feature that requires you to dial a number. For your convenience, we recommend using only phones that use only TONE or that are TONE/PULSE switchable. 17 Receiving Calls Receiving calls on a telephone connected to the SAU-1900E is identical to receiving calls on a standard wire-line service. When a telephone that is connected to the SAU-1900E rings, simply follow the telephones instructions for receiving a call. Advanced Features Your service provider may support other features such as CALLER ID, CALL WAITING, CALL FORWARDING, 3-WAY CALLING and other similar features. If you are interested in using these features contact your service provider for details. DATA COMMUNICATIONS/MODEMS/FAXES/ETC. Your SAU-1900E will provide quality voice communications, but it will not support data communications, such as using an analog modem or facsimile machine

(fax machine). If you need these types of services, contact your service provider or dealer about the MDL-1 Analog Fax/Data Service option for your SAU-1900E. THE BATTERY, AND WHEN TO REPLACE IT Your SAU-1900E comes with a sealed lead-acid battery for supplying backup power in the event of an outage, or brownout, of normal AC power. Under normal usage conditions your battery can be used for up to four years. The battery allows you to place or receive a call even after AC power has been lost for a short time (known as backup time). The actual backup time will vary with the age of the battery, how many times it has been charged and discharged, and distance from the telephone service providers RF transmitter/receiver. However, you should consider replacing the battery if any one or more of the following occurs:

1. The battery is older than fours years. 2. While AC power is removed from the SAU-1900E (by unplugging the AC power supply from the wall outlet), the battery indicator does not blink every 2-3 seconds. 3. No sound can be heard out of a telephone connected to the SAU-1900E when the AC power supply adapter is not powered (by unplugging the AC power supply from the wall outlet). 18 4. It can no longer provide 1 hour of talk-time following a full charge (a battery will reach a near-full charge condition after AC power has been on for 24 hours continuously). 5. When it no longer can provide at least 16 hours of standby time following a full charge (a battery will reach a near-full charge condition after AC power has been on for 24 hours continuously). Battery Replacement 1. Before you begin, make sure that you have purchased a new battery. 2. Place the antenna down into the down position, or if you are using an external antenna, disconnect the antenna. 3. Disconnect the SAU-1900Es AC power supply from the wall outlet, and then from the back/top of the SAU-1900E. 4. Disconnect all telephone lines that are plugged into the back/top of the SAU-1900E. 5. If you have installed your SAU-1900E using the desktop installation, skip to step 14. Otherwise, you will need a small, Phillips head screwdriver. 6. Place a soft cloth on a flat work surface, such as a table. 7. Holding onto the top of the SAU-1900E with one hand, push the bottom of the SAU-

1900E up gently until you feel it unlock. 8. Pull the SAU-1900E gently toward you. It should come off the wall plate. 9. Unplug the short telephone cable that is plugged into the wall plate. 10. Remove the short telephone cable from the bracket by pulling the cable through the small opening in the bracket between the prongs. Save this cable, you will need it to reinstall the SAU-1900E. 11. Place the SAU-1900E on the soft cloth, with the bracket side up and the screws toward you. 12. Unscrew the screws that are holding the bracket in place. 13. Move the end of the bracket where the screws were located up slightly, and then pull the bracket toward you to remove the bracket. 19 14. Turn the SAU-1900E upside down onto a soft cloth (this has already been done if you had a wall-mount installation) and orient the SAU-1900E such that the three semi-

circular/ridged cover release latches are toward you. 15. Remove the battery cover by depressing the semi-circular/ridged cover release latches while pushing the cover away from you. It should move toward the edge opposite you. Slide the cover completely out. 16. Remove the battery. This is easily accomplished by holding onto the SAU-1900E with one hand while still laying on the table, and gently pulling the exposed battery strap straight up until the battery comes loose from the battery compartment. (If for some reason the battery strap is not available, is damaged, etc. The battery can also be removed by turning the SAU-1900E over while holding your hand under the battery with the battery facing the floor and then gently tapping the edge of the SAU-1900E onto a tabletop until the battery slides out. Do not drop the battery as this may cause it to leak acid). 17. Follow the instructions in the section entitled Battery Installation, starting with step

#5, to install your new battery. 18. If you had installed your SAU-1900E on a wall, follow the instructions in the section entitled Wall-Mount Installation to reattach the bracket and mount the SAU-1900E to a wall plate. 19.
