WARNING This radio is capable of transmitting on Marine VHF. The FCC allows the use of VHF Marine band on water areas only. How-

ever the FCC does not allow the use of the VHF Marine band when on land. If persons use the VHF Marine Band on land and interfere with others communicating, the FCC will be notified and search for the inter-

ference. Responsible parties found to be transmitting on the VHF Ma-

rine Band on land could be fined up to $10,000 for the first offense. HX280S Page 3 RF EXPOSURE SAFETY STATEMENT SAFETY INFORMATION Your wireless handheld portable transceiver contains a low power trans-

mitter. When the Push-to-Talk (PTT) button is pushed, the transceiver sends out radio frequency (RF) signals. In August 1996, the Federal Communications Commission adopted RF exposure guidelines with safety levels for hand-held wireless devices. This device is authorized to operate at a duty factor not to exceed 50%

(this corresponds to 50% transmission time and 50% reception time). WARNING: To maintain compliance with the FCCs RF exposure guide-

lines, this transmitter and its antenna must maintain a separation dis-

tance of at least 1 inch (2.5 centimeters) from your face. Speak in a normal voice, with the antenna pointed up and away from the face at the required separation distance. Use only the supplied antenna. Unauthorized antennas, modifications, or attachments could damage the transmitter, and may violate FCC regu-

lations. Page 4 HX280S FCC AND CANADA RADIO LICENSE INFORMATION Standard Horizon radios comply with the Federal Communication Commis-

ABOUT THIS RADIO 3.1 ABOUT THE VHF MARINE BAND WARNING The radio frequencies used in the VHF marine band lie between 156 and 158 MHz with NOAA Weather stations available between 161 and 163 MHz. The marine VHF band provides communications over dis-

tances that are essentially Line of sight Actual transmission range de-

pends much more on antenna type, gain and height than on the power output of the transmitter. On a fixed mount 25 W radio transmission expected distances can be greater than 15 miles, for a portable 5 W radio transmission the expected distance can be greater than 5 miles in Line of sight. The user of a Marine VHF radio is subject to severe fines if the radio is used on land. The reasoning for this is you may be near an inland water-

way, or propagation anomalies may cause your transmission to be heard in a waterway. If this occurs, depending upon the marine VHF channel on which you are transmitting, you could interfere with a search and rescue case, or contribute to a collision between passing ships. For VHF Marine channel assignments refer to page 32 section 9. HX280S Page 9 4. GETTING STARTED 4.1 RADIO CARE CAUTION Before following the instructions below, insure the battery pack is in place and firmly tightened. Care must be taken if the radio was dropped and a close inspection may be needed to insure the radio case and gaskets are in adequate condition. Clean the radio with fresh water after exposure to salt water by rinsing the radio under a sink faucet or by dunking the radio in a bucket of fresh water. After washing, use a soft cloth and thoroughly dry all parts of the radio. This is to keep the rubber switches and speaker grill clean and in top operating condi-

tion. 4.2 BATTERIES AND CHARGERS If the radio has never been used, or its charge is depleted, it may be charged by connecting the CD-46 Charger Cradle with the NC-90B battery charger, as shown in the illustration. If 12V DC power is available, the optional E-DC-19A DC Cable with 12 V Cigarette Lighter Plug or the optional E-DC-6 DC Cable may be used for charging the battery. The NC-90B, E-DC-19A, and E-DC-6 will charge a completely discharged FNB-V105LI battery pack in about 6 hours. The FNB-V105LI is a high performance Li-Ion battery providing high capacity in a compact package. To avoid risk of explosion and injury, FNB-V105LI battery pack should only be removed, charged or recharged in non-hazardous environments. CAUTION 4.2.1 BATTERY SAFETY Battery packs for your transceiver contain Li-Ion batteries. This type of battery stores a charge powerful enough to be dangerous if misused or abused, espe-

cially when removed from the transceiver. Please observe the following pre-

cautions:

DO NOT SHORT BATTERY PACK TERMINALS: Shorting the terminals that power the transceiver can cause sparks, severe overheating, burns, and bat-

tery cell damage. If the short is of sufficient duration, it is possible to melt battery components. Do not place a loose battery pack on or near metal sur-

faces or objects such as paper clips, keys, tools, etc. When the battery pack is installed on the transceiver, the terminals that transfer current to the trans-

ceiver are not exposed. The terminals that are exposed on the battery pack HX280S Page 10 when it is mounted on the transceiver are charging terminals only and do not constitute a hazard. DO NOT INCINERATE: Do not dispose of any battery in a fire or incinerator. The heat of fire may cause battery cells to explode and/or release dangerous gases. Battery Maintenance For safe and proper battery use, please observe the following:

Battery packs should be charged only in non-hazardous environments;

Use only STANDARD HORIZON-approved batteries;

Use only a STANDARD HORIZON approved charger. The use of any other charger may cause permanent damage to the battery. Follow charging instructions provided with the chargers.

Keep the battery contacts clean. Battery Storage Store the batteries in a cool place to maximize storage life. Since batteries are subject to self-discharge, avoid high storage temperatures that cause large self-discharge rates. After extended storage, a full recharge is recommended. Battery Recycling DO NOT PLACE USED BATTERIES IN YOUR REGULAR TRASH!

LI-ION BATTERIES MUST BE COLLECTED, RECYCLED OR DISPOSED OF IN AN ENVIRONMENTALLY SOUND MANNER. The incineration, land filling or mixing of Li-Ion batteries with the municipal solid waste stream is PROHIBITED BY LAW in most areas. Return batteries to an approved Li-Ion battery recycler. This may be where you purchased the battery. Contact your local waste management officials for other information regarding the environmentally sound collection, recycling and disposal of Li-Ion batter-

ies. HX280S Page 11 4.2.2 BATTERY INSTALLATION/REMOVAL

ceiver off and on by rotating the VOL knob. 6.10.2 MEMORY SCANNING (M-SCAN) 1. Select the desired channel to be included in the scan memory using the

[] or [] key. 2. Press the [MEM] key to store the channel into the transceivers scan memory. MEM will be displayed on the LCD. 3. Repeat steps 1 and 2 for all the channels to be scanned. 4. To delete a channel from the transceivers scan memory, select the memo-

rized channel, then press the [MEM] key to delete the channel from scan memory. 5. All channels programmed remain in the transceivers scan memory even if the power is turned off. 6. Adjust the SQL level until background noise is eliminated by pressing the

[SQL] key followed by the [] / [] key. 7. To start scanning, press the [SCAN(DW)] key. The scan proceeds from the lowest to the highest programmed channel and stops scanning when a transmission is re-

ceived. Scanning will resume when the incoming signal disappears at the end of the transmission. The MEM and SCN icon will HX280S Page 23 appear at the left of the channel number on the display during scanning. 8. To stop the scan, press the [SCAN(DW)] key. 6.10.3 PRIORITY SCANNING (P-SCAN) 1. Select the desired channel to be included in the scan memory using the

[] or [] key. 2. Press the [MEM] key to store the channel into the transceivers scan memory. MEM will be displayed on the LCD. 3. Repeat steps 1 and 2 for all the channels to be scanned. 4. To delete a channel from the transceivers scan memory, select the memo-

rized channel, then press the [MEM] key to delete the channel from scan memory. 5. All channels programmed remain in the transceivers scan memory even if the power is turned off. 6. Adjust the Squelch Level until background noise is eliminated by pressing the [SQL] key followed by the [] / [] key. 7. To start scanning, press the [SCAN(DW)] key. A SCN icon and blinking P and MEM icons will appears at the left of the channel number on the display during scanning. The scan proceeds between the memorized channels and the Priority Channel (Chan-

nel 16). As an example of priority scanning, let us say that ma-

rine channels 06, 07, and 08 are memorized in the transceivers scan memory. Priority scanning will proceed in the following sequence:

[CH06] (CH16) [CH07] (CH16)

[CH08] (CH16) [CH06] (CH16) [CH07] .....

: Priority Channel 4. Even when the transceiver stops and listens to the signal of a programmed channel, the transceiver will dual watch between this channel and the priority channel. This allows the radio to be able to receive calls on chan-

nel 16 (priority channel) even when the radio is receiving on another chan-

nel. 5. To stop the Priority Scanning, press the [SCAN(DW)] key. Page 24 HX280S 6.11 DUAL WATCH The Dual Watch feature allows the radio watch the Priority Channel Channel 16 and one other channel. 1. Select the desired channel using the [] or [] key. 2. Press and hold the [SCAN(DW)] key for two seconds to activate the Dual Watch feature. A icon will ap-

pear on the upper left of the display when the Dual Watch feature is activated. 3. When a transmission is received on the Priority Channel, the radio re-

ceives the Priority Channel until the incoming signal disappears. 4. When the radio receives a transmission on the working channel, the radio will dual watch between the working channel and Channel 16. 5. The Dual Watch feature will resume when the incoming signal disappears at the end of the transmission. 6. To stop the Dual Watch feature and return to normal operation, press and hold the [SCAN(DW)] key for two seconds again. 6.12 EMERGENCY (CHANNEL 16 USE) Channel 16 is known as the Hail and Distress Channel. An emergency may be defined as a threat to life or property. In such instances, be sure the trans-

ceiver is on and set to Channel 16. Then use the following procedure:

1. Press the PTT (Push-To-Talk) switch and say Mayday, Mayday, Mayday. 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. 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 PTT switch and listen. 10. If there is no answer, repeat the above procedure. If there is still no re-

sponse, try another channel. HX280S Page 25 6.13 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 contact. For example, Channels 68 and 69 of the U.S. VHF Charts 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, im-

mediately request another channel by saying go to, the number of the other channel, 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 PTT (Push-To-Talk) switch. When all communication with the other vessel is completed, end the last trans-

mission by stating your Call Sign and the word out. Note that it is not neces-

sary to state your Call Sign with each transmission, only at the beginning 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. Page 26 HX280S 6.14 OPERATING ON CHANNEL 13 Channel 13 is used at docks, bridges and for maneuvering in port. Messages on this channel must concern navigation only, such as meeting and passing in restricted waters. In emergencies and when approaching blind river bends,

High power is allowed. Pressing the [H/L(

put from Low Power (1 Watt) to High (5 Watts). When you change from this channel then return to it, low power will be automatically selected. 6.15 OPERATING ON CHANNEL 67 When channel 67 is used for navigational bridge-to-bridge traffic between ships, Normal, High or Medium power may be used temporarily (in the USA band) by pressing the [H/L(

)] key. When you select this channel again, the trans-

ceiver will revert to low power. HX280S Page 27 7. MENU (SET) MODE The HX280Ss Menu Mode allows a number of the HX280S operating param-

VHF MARINE CHANNEL ASSIGNMENTS Tables on the following pages 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. Chan-

nel 22 (without an A) is an International duplex channel for port opera-

tions. Some radios indicate an A adjacent to the alpha channels on the display; on others alpha is not indicated but the proper channel is se-

lected based on the U/I/C setting. 3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge operators on inter-coastal 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. 4. The S/D column on the chart indicates either S (simplex) or D (duplex). Sim-

plex 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 transmission. Duplex op-

eration involves the use of one frequency for transmitting and a separate fre-

quency 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. 6. Marine vessels equipped with VHF radios are required to monitor Channel 16.
