pliance with FCC Rules. Any change or modification must be approved in writing by Marine Division of Vertex Standard. NOTICE This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful in-

terference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to ra-

dio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be deter-

mined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

- Reorient or relocate the receiving antenna.

- Connect the equipment into an outlet on a circuit different from that to Increase the separation between the equipment and receiver. which the receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help. GX3500S Page 7 7 GETTING STARTED 7.1 ABOUT VHF RADIO The radio frequencies used in the VHF marine band lie between 156 and 158 MHz with some shore stations available between 161 and 163 MHz. The ma-

rine VHF band provides communications over distances that are essentially line of sight (VHF signals do not travel well through objects such as buildings, hills or trees). Actual transmission range depends much more on antenna type, gain and height than on the power output of the transmitter. On a fixed mount 25W radio transmission expected distances can be greater than 15 miles. 7.2 SELECTING AN ANTENNA Marine antennas are made to radiate signals equally in all horizontal directions, but not straight up. The objective of a marine antenna is to enhance the signal toward the horizon. The degree to which this is accomplished is called the antennas gain. It is measured in decibels (dB) and is one of the major factors in choosing an antenna. In terms of effective radiated power (ERP), antennas are rated on the basis of how much gain they have over a theoretical antenna with zero gain. A 3 foot, 3dB gain antenna represents twice as much gain over the imaginary antenna. Typically a 3 foot 3dB gain stainless steel whip is used on a sailboat mast. The longer 8 foot 6dB fiberglass whip is primarily used on power boats that require the additional gain. Page 8 GX3500S 7.3 COAXIAL CABLE VHF antennas are connected to the transceiver by means of a coaxial cable a shielded transmission line. Coaxial cable is specified by its diameter and construction. For runs less than 20 feet, RG-58/U, about 1/4 inch in diameter is a good choice. For runs over 20 feet but less than 50 feet, the larger RG-8X or RG-213/U should be used for cable runs over 50 feet RG-8X should be used. For installa-

tion of the connector onto the coaxial cable refer to the figure below. 1/16''

3/4''

1 1/8''

A dapter 3/4''

To get your coax cable through a fitting and into your boats interior, you may have to cut off the end plug and reattach it later. You can do this if you follow the directions that come with the connector. Be sure to make good soldered connections. GX3500S Page 9 8 INSTALLATION 8.1 LOCATION The radio can be mounted at any angle. Choose a mounting location that:

is far enough from any compass to avoid any deviation in compass read-

ing due to the speaker magnet provides accessibility to the front panel controls allows connection to a power source and an antenna has nearby space for installation of a microphone hanger the antenna must be mounted at least 3 feet from radio Note: To insure the radio does not affect the compass or radios performance is not affected by the antenna location, temporarily connect the radio in the de-

sired location and:

a. Examine the compass to see if the radio causes any deviation b. Connect the antenna and key the radio. Check to ensure the radio is operating correctly by requesting a radio check. 8.2 ELECTRICAL CONNECTIONS CAUTION Reverse polarity connections will damage the radio!

Connect the power cord and antenna to the radio. Antenna and Power Supply connections are as follows (see Figure 1):

keys on the microphone to select a different NOAA weather channel. 3. To exit from the NOAA weather channels, press the [WX] key. The trans-

ceiver returns to the channel it was on prior to a weather channel. 10.6.1 NOAA Weather Alert In the event of extreme weather disturbances, such as storms and hurricanes, the NOAA (National Oceanic and Atmospheric Administration) sends a weather alert accompanied by a 1050 Hz tone and subsequent weather report on one of the NOAA weather channels. When the Weather Alert feature is enabled (see GX3500S Page 25 section 12.9 WX ALERT), the transceiver is capable of receiving this alert if the following is performed:

1. Program NOAA weather channels into the transceivers memory for scan-

ning. Follow the same procedure as for regular channels under section 10.12. 2. Press the [SCAN] key once to start memory scanning or hold down the

[SCAN] key during memory scanning to start priority scanning. 3. The programmed NOAA weather channels will be scanned along with the regular-programmed channels. However, scanning will not stop on a nor-

mal weather broadcast unless a NOAA alert is received. 4. When an alert is received on a NOAA weather channel, scanning will stop and the transceiver will emit a loud beep to alert the user of a NOAA broadcast. 5. Press the [WX] key to stop the alert tone and receive the weather report. If the [WX] key is not pressed the alert tone will be emitted for 5 minutes and then the weather report will be received. NOTE The Weather Alert feature is also engaged while the transceiver is re-

ceiving on one of the NOAA weather channels. NOTE 10.6.2 NOAA Weather Alert Testing NOAA tests the alert system ever Wednesday between 11AM and 1PM. To test the QUANTUMs NOAA Weather feature, on Wednesday between 11AM and 1PM, setup as in previous section and confirm the alert is heard. 10.7 EMERGENCY (CHANNEL 16 USE) Channel 16 is known as the Hail and Distress Channel. An emergency is de-

fined as a threat to life or property. In such instances, be sure the transceiver is on and set to CHANNEL 16. Then use the following procedure:

1. Press the microphone push-to-talk switch and say Mayday, Mayday, May-

day. This is , , (your vessels name). 2. Then repeat once: Mayday, (your vessels name). 3. Now report your position in latitude/longitude, or by giving a true or mag-

netic bearing (state which) to a well-known landmark such as a navigation aid or geographic feature such as an island or harbor entry. 4. Explain the nature of your distress (sinking, collision, aground, fire, heart attack, life-threatening injury, etc.). 5. State the kind of assistance your desire (pumps, medical aid, etc.). 6. Report the number of persons aboard and condition of any injured. 7. Estimate the present seaworthiness and condition of your vessel. Page 26 GX3500S 8. Give your vessels description: length, design (power or sail), color and other distinguishing marks. The total transmission should not exceed 1 minute. 9. End the message by saying OVER. Release the microphone button and listen. 10. If there is no answer, repeat the above procedure. If there is still no re-

sponse, try another channel. 10.8 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9) Channel 16 may be used for initial contact (hailing) with another vessel. However, its most important use is for emergency messages. This channel must be monitored at all times except when actually using another channel. It is monitored by the U.S. and Canadian Coast Guards and by other vessels. Use of channel 16 for hailing must be limited to initial contact only. Calling should not exceed 30 seconds, but may be repeated 3 times at 2-minute inter-

vals. In areas of heavy radio traffic, congestion on channel 16 resulting from its use as a hailing channel can be reduced significantly in U.S. waters by using channel 9 as the initial contact (hailing) channel for non-emergency communi-

cations. Here, also, calling time should not exceed 30 seconds but may be repeated 3 times at 2-minute intervals. Prior to making contact with another vessel, refer to the channel charts in this manual, and select an appropriate channel for communications after initial con-

tact. For example, Channels 68 and 69 are some of the channels available to non-commercial (recreational) boaters. Monitor your desired channel in advance to make sure you will not be interrupting other traffic, and then go back to either channel 16 or 9 for your initial contact. When the hailing channel (16 or 9) is clear, state the name of the other vessel you wish to call and then this is followed by the name of your vessel and your Station License (Call Sign). When the other vessel returns your call, immedi-

ately request another channel by saying go to, the number of the other chan-

nel, and over. Then switch to the new channel. When the new channel is not busy, call the other vessel. After a transmission, say over, and release the microphones push-to-talk

(PTT) switch. When all communication with the other vessel is completed, end the last transmission by stating your Call Sign and the word out. Note that it is not necessary to state your Call Sign with each transmission, only at the begin-

ning and end of the contact. Remember to return to Channel 16 when not using another channel. Some radios automatically monitor Channel 16 even when set to other channels or when scanning. GX3500S Page 27 10.9 MAKING TELEPHONE CALLS To make a radiotelephone call, use a channel designated for this purpose, The fastest way to learn which channels are used for radiotelephone traffic is to ask at a local marina. Channels available for such traffic are designated Public Correspondence channels on the channel charts in this manual. Some ex-

amples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87. Call the marine operator and identify yourself by your vessels name, The marine operator will then ask you how you will pay for the call (telephone credit card, collect, etc.) and then link your radio transmission to the telephone lines. The marine telephone company managing the VHF channel you are using may charge a link-up fee in addition to the cost of the call. 10.10 OPERATING ON CHANNELS 13 AND 67 Channel 13 is used at docks and bridges and by vessels maneuvering in port. Messages on this channel must concern navigation only, such as meeting and passing in restricted waters. Channel 67 is used for navigational traffic between vessels. By regulation, power is normally limited to 1 Watt on these channels. Your radio is programmed to automatically reduce power to this limit on these channels. However, in certain situations it may be necessary to temporarily use a higher power. See page 18 ([H/L] key) for means to temporarily override the low-power limit on these two channels. 10.11 DUAL WATCH (TO PRIORITY CHANNEL) Dual watch allows the radio to monitor one channel and the assigned Priority channel. By default the priority channel is set to 16, however the priority chan-

nel may be changed by referring to section 12.5 Priority Channel set. 1. Adjust the SQL knob until the background noise disappears. 2. Select the channel you wish to dual watch to Priority channel. 3. Press the [F] key followed by the [4(DW)] key.

JK L DI STR ES S P ULL OPEN Digital Selective Calling is a semi-automated method of establishing a radio call, it has been designated by the International Maritime Organization (IMO) as an international standard for establishing VHF, MF and HF radio calls. It has also been designated as part of the Global Maritime Distress and Safety Sys-

tem (GMDSS). It is planned that DSC will eventually replace aural watches on distress frequencies and will be used to announce routine and urgent maritime safety information broadcasts. This new system allows mariners to instantly send a distress call with GPS posi-

tion (when connected to the transceiver) to the Coast Guard and other vessels within range of the transmission. DSC will also allow mariners to initiate or receive Distress, Urgency, Safety, Routine, POSITION REQUEST, POSITION SEND, and Group calls to or from another vessel equipped with a DSC transceiver. Page 36 GX3500S 11.2 MARITIME MOBILE SERVICE IDENTITY (MMSI) 11.2.1 What is an MMSI?

An MMSI is a nine digit number used on Marine Transceivers capable of using Digital Selective Calling (DSC). This number is used like a telephone number to selectively call other vessels. THIS NUMBER MUST BE PROGRAMMED INTO THE RADIO TO OPERATE THE GX3500S DSC FUCTIONS. How can I obtain an MMSI assignment?

Boat US offers online registration of a MMSI. Visit www.boatus.com/mmsi 11.2.2 Programming the MMSI WARNING User MMSI can be input only twice.

Transceiver blows fuse when connected to power supply. R e v e r s e d p o w e r wires. Popping or whining noise from the speaker while engine runs. Engine noise. Accessory cable. Antenna. a. Check the 12VDC battery connections and the fuse. b. The PWR key needs to be pressed and held to turn the radio on. Check the power cable for DC voltage, or re-

place the fuse (6A 250V). Make sure the red wire is connected to the posi-

tive (+) battery post, and the black wire is con-

nected to the negative (-) battery post. If the fuse still blows, contact your Dealer. Reroute the DC power cables away from the engine. Add noise suppressor on power cable. Change to resistive spark plug wires and/or add an alternator whine filter. Check the connections of the accessory cable

(Possible short circuit on the External speaker cable WHITE/SHIELD). Have the antenna checked or test the trans-

ceiver with another antenna. If the problem per-

sists, contact your Dealer for servicing. The power supply voltage is too high or too low. Confirm that the connected power supply volt-

age is not 17 volts or lower than 10 volts. Con-

firm that the generator has not malfunctioned. Accessory cable. Check the accessory cable connection (Pos-

sible short circuit on the PA speaker cable RED/

SHIELD). Accessory cable. Setting of the GPS navigation receiver. Check the accessory cable connection. Some GPS use the battery ground line for NMEA connection. Check the output signal format of the GPS navi-

gation receiver. This radio requires NMEA0183 format with GLL, RMB, GGA, or GNS sentence as an output signal. If the GPS has a baud rate setting make sure to select 4800 and parity to NONE. Sound is not emitted from the internal or ex-

ternal speaker. Receiving station re-

vated. Your position is not dis-

played. Page 76 GX3500S 15. CHANNEL ASSIGNMENTS Tables on the following columns list the VHF Marine Channel assignments for U.S.A. and International use. Below are listed some data about the charts. 1. VTS. Where indicated, these channels are part of the U.S. Coast Guards Vessel Traffic System. 2. Alpha channel numbers, that is, channel numbers followed by the letter A

(such as Channel 07A) are simplex channels on the U.S.A. or Canadian channel assignments whose counterparts in the International assignments are duplex channels. International channels do not use alpha numbers. If you call the Coast Guard on Channel 16, they will sometimes ask you to go to channel 22 Alpha. This is a channel assigned to U.S.A, and Cana-

dian Coast Guards for handling distress and other calls. If your radio is set for International operation you will go to Channel 22 instead of 22A, and will not be able to communicate with the Coast Guard. To use Channel 22A, your radio must be set for USA or Canada operation, usually by a U/I/C

(USA/International/Canada) control or combination of controls. Channel 22

(without an A) is an International duplex channel for port operations. Some radios indicate an A adjacent to the alpha channels on the display;

on others alpha is not indicated but the proper channel is selected based on the U/I/C setting. 3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge operators on intercoastal waterways and rivers. It is also used by marine vessels in the vicinity of these bridges for navigation and for communicat-

ing with the bridge operators. Note that a limit of 1 Watt is specified for these channels. See page 27 for additional information. 4. The S/D column on the chart indicates either S (simplex) or D (duplex). Simplex means transmitting and receiving on the same frequency. Only one party at a time can talk, unlike a telephone. Be sure to say over and release your microphone push-to-talk switch at the end of each transmis-

sion. Duplex operation involves the use of one frequency for transmitting and a separate frequency for receiving. On channels specified as duplex on the charts, correct mode of operation is established automatically by your radio when you select a channel; you cannot change the mode. And you still must release the push-to-talk switch after each transmission in order to listen to the radio. 5. Channels normally used by recreational boaters are those that include the term non-commercial in the Channel Use column of the chart. Some of these are shared with other users and some are used only in certain geo-

graphic regions. GX3500S Page 77 6. Marine vessels equipped with VHF radios are required to monitor Channel 16.
