WARNING This radio generates RF electromagnetic energy during transmit mode. This radio is designed for and classified as Occupational Use Only, meaning it must be used only during the course of employment by individuals aware of the hazards, and the ways to minimize such hazards. This radio is not in-

tended for use by the General Population in an uncontrolled environment. To ensure that your expose to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines:

CAUTION SAFETY INFORMATION This radio is NOT approved for use by the general population in an uncon-

trolled environment. This radio is restricted to occupational use, work re-

lated operations only where the radio operator must have the knowledge to control its RF exposure conditions. H When transmitting, hold the radio in a vertical position with its microphone 1 to 2 inches (2.5 to 5 cm) away from your mouth and keep the antenna at least 1 inch (2.5cm) away from your head and body. H The radio must be used with a maximum operating duty cycle not exceed-

ing 50 %, in typical Push-to-Talk (Manual PTT or VOX) configurations. DO NOT transmit for more than 50 % of total radio use time (50 % duty cycle). Transmitting more than 50 % of the time can cause FCC RF expo-

sure compliance requirements to be exceeded. The radio is transmitting when the red LED on the front panel of the radio is illuminated. You can cause the radio to transmit by pressing the PTT button or by speaking into the microphone if using the optional VC-24 VOX accessory.

We appreciate your purchase of the HX370S, and encourage you to read this manual thoroughly, so as to learn and understand the capabilities of the HX370S fully. ABOUT VHF MARINE 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 marine 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 de-

pends much more on antenna type, gain and height than on the power output of the transmitter. The approximate distance a portable 5W radio may communicate is about 5 miles in if there are no obstructions (build-

ings, hills etc.) restricting line of sight transmission. ABOUT LMR CHANNELS The HX370S is capable of PC programming 40 LMR (Land Mobile Ra-

dio) channels by a dealer. The frequency range is 137 to 174MHz which may be setup for 25kHz (wide) or 12.5kHz (narrow) channel stepping with CTCSS and DCS signaling. Contact your dealer or Standard Horizon Product Support (800-767-2450) for further details.

Insert the transceiver and battery pack into the CD-26; the antenna jack should be at the left side when viewing the charger from the front. If the transceiver and battery pack are in-

serted correctly, the Red indicator on the CD-26 will glow. A fully-discharged pack will be charged completely in 10 hours. 4. Figure 2 Important Notes:

H The NC-88 is not designed to power the transceiver for operation (re-

ception or transmission). H Do not leave the charger connected to the transceiver for continuous periods in excess of 24 hours. Long term overcharging can degrade the Ni-MH battery pack and significantly shorten its useful life. H If using a charger other than the NC-88/CD-26, or if using a battery pack other than the FNB-83/FNB-V57IS, follow the appropriate instructions provided with the charger/battery. Contact your Dealer if you have any doubts about the appropriateness of the particular charger or battery pack you intend to use. 3.4 FBA-25A Waterproof Alakline Battery Tray FBA-25A is a battery case that holds six alkaline batteries and is used with the HX370S transceiver. When installing batteries, insert the () end first, then press in the (+) end so the battery snaps into place. Always replace all six batteries at the same time, paying attention to the polarity indicated inside the case. The FBA-25A must not be used with rechargeable cells. The FBA-

25A does not contain the thermal and over-current protection circuits (provided in the "FNB" series of Ni-MH Battery Packs) required when utilizing Ni-Cd and Ni-MH cells. Page 8 HX370S 3.5 BATTERY SAFETY Battery packs for your transceiver contain Ni-MH/Ni-Cd batteries. This type of battery stores a charge powerful enough to be dangerous if misused or abused, especially when removed from the transceiver. Please observe the following precautions:

DO NOT SHORT BATTERY PACK TERMINALS Shorting the terminals that power to the transceiver can cause sparks, se-

vere overheating, burns, and battery 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 surfaces or objects such as paper clips, keys, tools, etc. When the battery pack is installed on the transceiver, the termi-

nals that transfer current to the transceiver are not exposed. 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. Caution Never short-circuit the connection terminals on the bat-

tery or charger !

ceiver on. 2. Press the SQL key, then press the [] key until the SQL level is 00. 3. Turn up the POWER/VOLUME CONTROL knob un-

til the noise or audio from the speaker is at a comfortable level. 4. Select a channel that has no signal being received (no one is transmit-

ting on the channel) and where only noise is heard. 5. Press the SQL key, then press the [] key and stop immediately after the noise disappears. This condition is known as the Squelch Thresh-

old. If the squelch is set to a higher level, weak signals may not be received. 6. To change channels, press the [] or [] key. 7. The LCD and keypad are illuminated for 5 seconds when any key is pressed. The lamp automatically turns off in 5 seconds. 8. To lock the channel so that it is not accidentally changed, hold down the H/L key for about one second. This locks the [] and [] buttons and all the front panel controls except the H/L, PTT and SQL keys. The symbol will appear on the display to indicate that the keypad is locked. Hold down the H/L key for about one second to unlock the keys. The sym-

bol will disappear from the display. LMR (Land Mobile Radio) Channels The HX370S is capable of PC programming 40 LMR (Land Mobile Ra-

dio) channels by a dealer. Contact your dealer or Standard Horizon Product Support (800-767-

2450) for further details. Typical display of LMR operation. Page 16 HX370S 5.3 TRANSMISSION NOTE Never key the transceiver without an antenna connected, as this may cause damage to the transceiver. 1. Perform steps 1 through 7 of the RECEPTION discussion above. 2. Before transmitting, monitor the channel and make sure it is clear. THIS IS AN FCC REQUIREMENT!

3. For communications over short distances, press the H/L key until is displayed on the LCD. This indicates Low power (approximately 1 Watt). NOTE Transmitting on 1 Watt prolongs battery life. Low power (1 Watt) should be selected whenever possible. 4. If using Low power is not effective, select Medium power (2.5 Watts) or High power (5 Watts) by pressing the H/L key until

(High power) is dis-

played.

(Medium power) or 5. When receiving a signal, wait until the incoming signal stops before trans-

mitting. The transceiver cannot transmit and receive simultaneously. 6. Press the PTT (Push-To-Talk) switch to transmit. The TX indicator is displayed during transmission. 7. Speak slowly and clearly into the microphone. Hold the microphone about to 1 inch away from your mouth. 8. When the transmission is finished, release the PTT switch. 5.4 TRANSMIT TIME - OUT TIMER (TOT) While the PTT switch is held down, transmission time is limited to 5 minutes. This prevents prolonged (unintentional) transmissions. About 10 seconds before automatic transmitter shutdown, a warning beep sounds from the speaker. The transceiver automatically switches to the receiving mode, even if the PTT switch is held down. Before transmitting again, the PTT switch must first be released, then pressed again. This Time-Out Timer (TOT) pre-

vents a continuous transmission that would result from an accidentally stuck PTT switch. HX370S Page 17 5.5 USA, CANADIAN, AND INTERNATIONAL BANDS 1. To change the operating band (channel set) of the transceiver, hold down the 16/9 key and press the WX key. The band will change from USA, to International, and to Canadian with each press. USA appears on the LCD for the USA band, INTL appears for the International band, and CAN ap-

pears for the Canadian band. 2. 5.6 NOAA WEATHER CHANNELS 1. To receive a NOAA weather channel, press the WX key. The transceiver changes to the weather channel mode. This mode consists of a special pre-set memory bank containing the standard NOAA weather channels. 2. The transceiver will be set to the last-used NOAA weather channel. Press the [] or [] key to change to other weather channels. 3. To exit from the weather channel mode, press the WX key. The transceiver will revert to the channel you were using prior to switching to the weather chan-

nel mode. 5.6.1 NOAA WEATHER ALERT In the event of extreme weather disturbances such as storms and hurri-

canes, NOAA (National Oceanic and Atmospheric Administration) sends a weather alert consisting of a 1050 Hz tone, followed by weather reports on the weather channels. The transceiver is capable of receiving this alert if the following is performed:

1. Program your areas weather channels into the transceivers scan memory. Follow the same procedure as for regular channels under Sec-

tion 5.7. 2. Press the SCAN key to start the scan. 3. The memorized weather channels are scanned along with the regular memorized channels. Scanning will not stop, however, on the (continu-

ous) weather broadcast channels unless the weather alert tone is re-

ceived. 4. When an alert is received on a weather channel, scanning stops and the transceiver emits a beeping tone that will stay on for 5 minutes or until the user presses the WX key to listen to the Weather Alert. Page 18 HX370S 5.6.2 NOAA WEATHER ALERT TESTING In the event of a major storm or other appreciable weather condition requir-

ing vessels at sea or other bodies of water to be notified, the NOAA (Na-

tional Oceanographic and Atmospheric Administration) broadcasts a 1050 Hz tone that the HX370S can detect. (Refer to section 5.6.1 NOAA WEATER ALERT on how to use this feature.) This tone, when detected, will produce a loud beep from the radio speaker to signal that a weather alert is being broadcast. In order to test this system, the NOAA broadcasts the 1050 Hz tone every Wednesday, sometime between 11 AM and 1 PM. Any marine VHF radio that can detect the weather alert tone, may use this test to verify that this feature is functioning properly. NOTICE Take care not to damage your hearing when operating with the optional VC-24 VOX Headset or Earpiece. The NOAA Weather Alert Tone will be emitted at full volume, irrespective of the setting of the POWER/VOL-

UME CONTROL knob. HX370S Page 19 5.7 SCAN This transceiver provides a special Scanning Memory Bank which allows you to designate certain channels for inclusion in a loop which will be scanned at high speed. If an incoming signal is detected on one of the chan-

nels in the scanning loop, the radio will pause on that channel, allowing you to listen to the incoming transmission. 1. Select the desired channel to be included in the scanning loop using the

[] or [] key. 2. Press the MEM key to store the channel into the transceivers scanning memory. MEM will be dis-

played 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, press the MEM key again while the memorized channel is displayed. MEM will disap-

pear from the display. 5. All channels programmed remain in the transceivers scan memory even if the power is turned off. See section 5.20: RESETTING THE TRANSCEIVERS MICROPROCESSOR to clear all channels from the transceivers scan memory. 6. Press the SQL key, then press the [] or [] key until background noise is eliminated. 7. To start scanning, press the SCAN key. The scan proceeds from the lowest to the highest programmed channel number and stops on chan-

nels when a transmission is received. Scanning will resume when the squelch closes after the incoming signal disappears at the end of the transmission. 8. To stop the scan, press the SCAN, 16/9, or WX key. Page 20 HX370S 5.8 PROGRAMMABLE PRIORITY SCAN The priority scanning feature allows the radio to scan while also keeping watch on a particularly important priority channel. The following channels can be set as the priority channel: 16, 09, and Preset Channels 1 through 8

(Preset Channels are described in section 5.14). 1. To set the priority channel, hold down the 16/9 key and press the MEM key. The channel will change from 16 to 09 to Preset 1 to Preset 2 to Preset 3 to Preset 4 to Preset 5 to Preset 6 to Preset 7 to Preset 8 with each press of the MEM key. The displayed channel will be set as the priority channel when the 16/9 key is released. 2. For priority scanning, hold down the SCAN key during normal scanning. Scanning will proceed between the memorized channels and the priority channel. The priority channel will be scanned after each programmed channel. P is shown on the left side of the channel number during pri-

ority scanning. 3. As an example of priority scanning, let us say that channels 06, 07, and 08 are memorized in the transceivers scan memory. Priority scanning will proceed in the following sequence:

[CH06]  [Priority Channel]  [CH07]  [Priority Channel] 

[CH08]  [Priority Channel]  [CH06]  [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. Therefore, your priority watching of the designated chan-

nel is not compromised when the scanner has paused on an active channel. 5.9 DUAL WATCH The Dual Watch feature allows the radio to watch for a transmission on the priority channel and another selected Marine channel until a signal is re-

ceived. The priority channel is determined per the discussion in section 5.8 PROGRAMMABLE PRIORITY SCAN as described previously. 1. To start the Dual Watch feature, select a channel to be dual watched with the priority channel and press and hold in the SCAN key. The radio checks the priority channel for voice traffic every one second. A small DW icon will be shown blinking on the left of the display dur-

ing scanning. 2. To cancel the Dual Watch feature, press the SCAN key. HX370S Page 21 5.10 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 transceiver is on and set to CHANNEL 16. Then use the following proce-

dure:

1. Press the microphone push-to-talk switch and say Mayday, Mayday, Mayday. This is , , (your vessel's name). 2. Then repeat once: Mayday, (your vessel's 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 naviga-

tion 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 microphone button and listen. 10. If there is no answer, repeat the above procedure. If there is still no response, try another channel. 11. To recall the previously-selected channel, press the 16/9 key again. 5.11 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 ves-

sels. 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 intervals. 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 communications. Here, also, calling time should not exceed 30 seconds but may be repeated 3 times at 2-minute intervals. Page 22 HX370S 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 inter-

rupting 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, immediately request another channel by saying go to, the num-

ber 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 microphone's 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 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; see your Owner's Manual. 5.12 OPERATING ON CHANNEL 13 Channel 13 is used at docks, bridges and for maneuvering in port. Mes-

sages 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 key will change the power output from 1 Watt (

); if pressed again, 2.5 Watts

) will be selected. When the PTT switch is released, the transceiver will revert to Low power. Press the H/L key again if you need High power on a subsequent transmission.

) to 5 Watts (

5.13 OPERATING ON CHANNEL 67 When channel 67 is used for navigational bridge-to-bridge traffic between ships, High or Medium power may be used temporarily (in the USA band) by pressing the H/L key. When the PTT switch released, the transceiver will revert to low power.

Hold down the PRESET key, and press the [] or [] key (repeatedly, if necessary) until the desired channel number (from among the regular operating channels) is displayed. 2. With the desired channel number displayed, release the PRESET key. The 1 notation will appear on the LCD display for 1 second, indicating that the displayed channel is now saved in the Pre-

set Channel 1 position. Then the preset channel number will disappear and the display comes back to the normal channel display. Repeat steps 1 and 2 to program the desired channels into Preset Channels 1 ~ 8. To delete a Preset Channel, hold down the PRESET key and press the []

or [] key until the Preset Channel number to be deleted is displayed, then release the PRESET key. 5.14.2 Operation Pressing the PRESET key toggles between Preset Channel 1, 2, 3, 4, 5, 6, 7, 8 and the last selected regular channel. Preset Channel 1 is repre-

sented by 1 to the right of the channel number on the LCD for 1 second, and channel 2 is represented by 2, and so forth. Then the preset channel numberr will disappear and the display comes back to the normal channel display. Page 24 HX370S 5.15 SIMPLEX/DUPLEX CHANNEL USE All channels are factory-programmed in accordance with FCC (USA), In-

dustry Canada and International regulations. The mode of operation cannot be altered from simplex to duplex or vice-versa. Simplex or duplex mode is automatically activated, depending on the channel and whether the USA, International or Canadian operating band is selected. 5.16 ENABLING S.O.S STROBE OPERATION The S.O.S. STROBE feature utilizes the high-intensity strobe LED on the front of the HX370S as a visual distress beacon. When enabled, the LED blinks the internationally-recognized Morse Code S.O.S. message

( ) at a rate of 5 words per minute. This can be very useful in summoning help from rescuers who may not be able to communicate with you via radio. 1. Hold down the MEM key while turning the radio on to activate the emer-

gency S.O.S. Strobe. Once the radio comes on, the BUSY/TX LED will flash the Morse Code S.O.S. message repeatedly. 2. The S.O.S strobe will not operate if the squelch is turned off (Squelch must be set to threshold), the radio is receiving a transmission or trans-

mitting. 3. To disable the S.O.S. strobe function, turn the radio off and back on again. HX370S Page 25 5.17 VOICE SCRAMBLER UNIT The optional FVP-31 Voice Scrambler Unit permits secure voice communica-

If the data transfer is successful, the Destination transceiver will return to normal operation; Turn both transceivers off and disconnect the Clone cable. You can then turn the transceivers back on, and begin normal operation. Page 30 HX370S 5.20 RESETTING THE TRANSCEIVERS MICROPROCESSOR Resetting the microprocessor restores the initial, factory-supplied conditions in the transceiver. These are called the default conditions. To reset the microprocessor, first turn the transceiver off. Then, while pressing and hold-

ing in the WX and SCAN keys, turn the transceiver on. The default condi-

tions are:

No channel numbers are in scan memory. Channel 16 is the priority channel. Channel 16 will be selected when the transceiver is turned on. WX channel 01 will be recalled when the WX key is pressed. Preset Channels are unassigned. NOTE The above procedure also resets the microprocessor. Perform this pro-

cedure if an operational problem occurs which cannot be solved by nor-

mal operating procedures. HX370S Page 31 6. MAINTENANCE To receive warranty service, the purchaser must deliver the Product, trans-

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 Cana-

dian channel assignments whose counterparts in the International as-

signments are duplex channels. International channels do not use Al-

pha numbers. If you call the Coast Guard on Channel 16, they will some-

times ask you to go to channel 22 Alpha. This is a channel assigned to U.S.A, and Canadian Coast Guards for handling distress and other calls. If your radio is set for International operation you will go to Chan-

nel 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) con-

trol or combination of controls. Channel 22 (without an A is an Interna-

tional 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 communi-

cating with the bridge operators. Note that a limit of 1 Watt is specified for these channels. See page 23 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 trans-

mission. Duplex operation involves the use of one frequency for trans-

mitting and a separate frequency for receiving. On channels specified HX370S Page 33 as duplex on the charts, correct mode of operation is established auto-

matically 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 geographic regions. 6. Marine vessels equipped with VHF radios are required to monitor Channel 16.
