Whether this is your firstportable marine VHF transceiver, or if you have other STANDARD HORIZONequipment, the STANDARD HORIZON organization is committed to ensur-ing your enjoyment of this high-performance transceiver, which should pro-vide you with many years of satisfying communications even in the harshestof environments. STANDARD HORIZON technical support personnel standbehind every product we sell, and we invite you to contact us, should yourequire technical advice or assistance, at (800)767-2450.We appreciate your purchase of the HX370S, and encourage you to readthis manual thoroughly, so as to learn and understand the capabilities of theHX370S fully.Page 2ABOUT VHF MARINE RADIOThe radio frequencies used in the VHF marine band lie between 156and 158 MHz with some shore stations available between 161 and 163MHz. The marine VHF band provides communications over distancesthat are essentially “line of sight” (VHF signals do not travel well throughobjects such as buildings, hills or trees). Actual transmission range de-pends much more on antenna type, gain and height than on the poweroutput of the transmitter. The approximate distance a portable 5W radiomay communicate is about 5 miles in if there are no obstructions (build-ings, hills etc.) restricting line of sight transmission.ABOUT LMR CHANNELSThe HX370S is capable of PC programming 40 LMR (Land Mobile Ra-dio) channels by a dealer. The frequency range is 137 to 174MHz whichmay be setup for 25kHz (wide) or 12.5kHz (narrow) channel steppingwith CTCSS and DCS signaling. Contact your dealer or Standard HorizonProduct Support (800-767-2450) for further details.

The band will change from USA, toInternational, and to Canadian with each press.2. “USA” appears on the LCD for the USA band, “INTL”appears for the International band, and “CAN” ap-pears for the Canadian band.5.6 NOAA WEATHER CHANNELS1. To receive a NOAA weather channel, press the WX key. The transceiverchanges to the weather channel mode. This mode consists of a specialpre-set memory bank containing the standard NOAA weather channels.2. The transceiver will be set to the last-used NOAA weather channel. Pressthe [] or [] key to change to other weather channels.3. To exit from the weather channel mode, press theWX key. The transceiver will revert to the channelyou were using prior to switching to the weather chan-nel mode.5.6.1 NOAA WEATHER ALERTIn 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 onthe weather channels. The transceiver is capable of receiving this alert if thefollowing is performed:1. Program your area’s weather channels into the transceiver’s scanmemory. 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 regularmemorized 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 thetransceiver emits a beeping tone that will stay on for 5 minutes or untilthe user presses the WX key to listen to the Weather Alert.
HX370S Page 195.6.2 NOAA WEATHER ALERT TESTINGIn 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 1050Hz tone that the HX370S can detect. (Refer to section 5.6.1 “NOAA WEATERALERT” on how to use this feature.) This tone, when detected, will producea loud beep from the radio speaker to signal that a weather alert is beingbroadcast.In order to test this system, the NOAA broadcasts the 1050 Hz tone everyWednesday, sometime between 11 AM and 1 PM. Any marine VHF radiothat can detect the weather alert tone, may use this test to verify that thisfeature is functioning properly.NOTICETake care not to damage your hearing when operating with the optionalVC-24 VOX Headset or Earpiece. The NOAA Weather Alert Tone will beemitted at full volume, irrespective of the setting of the POWER/VOL-UME CONTROL knob.
HX370SPage 205.7 SCANThis transceiver provides a special “Scanning Memory Bank” which allowsyou to designate certain channels for inclusion in a “loop” which will bescanned 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 youto 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 thetransceiver’s 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 transceiver’s scan memory, press the MEMkey again while the memorized channel is displayed. “MEM” will disap-pear from the display.5. All channels programmed remain in the transceiver’s scan memory evenif the power is turned off. See section 5.20: “RESETTING THETRANSCEIVER’S MICROPROCESSOR” to clear all channels from thetransceiver’s scan memory.6. Press the SQL key, then press the [] or [] key until background noiseis eliminated.7. To start scanning, press the SCAN key. The scan proceeds from thelowest to the highest programmed channel number and stops on chan-nels when a transmission is received. Scanning will resume when thesquelch closes after the incoming signal disappears at the end of thetransmission.8. To stop the scan, press the SCAN, 16/9, or WX key.
HX370S Page 215.8 PROGRAMMABLE PRIORITY SCANThe priority scanning feature allows the radio to scan while also keepingwatch on a particularly important “priority channel.” The following channelscan 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 MEMkey. The channel will change from 16 to 09 to Preset 1 to Preset 2 toPreset 3 to Preset 4 to Preset 5 to Preset 6 to Preset 7 to Preset 8 witheach press of the MEM key. The displayed channel will be set as thepriority 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 prioritychannel. The priority channel will be scanned after each programmedchannel. “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, and08 are memorized in the transceiver’s scan memory. Priority scanningwill 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 programmedchannel, the transceiver will “dual watch” between this channel and thepriority 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 WATCHThe Dual Watch feature allows the radio to watch for a transmission on thepriority 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 watchedwith the priority channel and press and hold in theSCAN key. The radio checks the priority channel forvoice traffic every one second. A small “DW” iconwill be shown blinking on the left of the display dur-ing scanning.2.

HX370SPage 225.10 EMERGENCY (CHANNEL 16 USE)Channel 16 is known as the Hail and Distress Channel. An emergency maybe defined as a threat to life or property. In such instances, be sure thetransceiver 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, heartattack, 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 vessel’s description: length, design (power or sail), color andother distinguishing marks. The total transmission should not exceed 1minute.9. End the message by saying “OVER”. Release the microphone buttonand listen.10. If there is no answer, repeat the above procedure. If there is still noresponse, 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 channelmust 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 16resulting from its use as a hailing channel can be reduced significantly inU.S. waters by using Channel 9 as the initial contact (hailing) channel fornon-emergency communications. Here, also, calling time should not exceed30 seconds but may be repeated 3 times at 2-minute intervals.
HX370S Page 23Prior to making contact with another vessel, refer to the channel charts inthis manual, and select an appropriate channel for communications afterinitial contact. For example, Channels 68 and 69 of the U.S. VHF Charts aresome 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 initialcontact.When the hailing channel (16 or 9) is clear, state the name of the othervessel you wish to call and then “this is” followed by the name of yourvessel and your Station License (Call Sign). When the other vessel returnsyour call, immediately request another channel by saying “go to,” the num-ber of the other channel, and "over." Then switch to the new channel. Whenthe 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.” Notethat it is not necessary to state your Call Sign with each transmission, onlyat the beginning and end of the contact.Remember to return to Channel 16 when not using another channel. Someradios automatically monitor Channel 16 even when set to other channelsor when scanning; see your Owner's Manual.5.12 OPERATING ON CHANNEL 13Channel 13 is used at docks, bridges and for maneuvering in port. Mes-sages on this channel must concern navigation only, such as meeting andpassing in restricted waters. In emergencies and when approaching blindriver bends, High power is allowed. Pressing the H/L key will change thepower output from 1 Watt () to 5 Watts ( ); if pressed again, 2.5 Watts() will be selected. When the PTT switch is released, the transceiver willrevert to Low power. Press the H/L key again if you need High power on asubsequent transmission.5.13 OPERATING ON CHANNEL 67When channel 67 is used for navigational bridge-to-bridge traffic betweenships, High or Medium power may be used temporarily (in the USA band) bypressing the H/L key. When the PTT switch released, the transceiver willrevert to low power.

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 channelnumberr will disappear and the display comes back to the normal channeldisplay.
HX370S Page 255.15 SIMPLEX/DUPLEX CHANNEL USEAll channels are factory-programmed in accordance with FCC (USA), In-dustry Canada and International regulations. The mode of operation cannotbe altered from simplex to duplex or vice-versa. Simplex or duplex mode isautomatically activated, depending on the channel and whether the USA,International or Canadian operating band is selected.5.16 ENABLING S.O.S STROBE OPERATIONThe S.O.S. STROBE feature utilizes the high-intensity strobe LED on thefront of the HX370S as a visual distress beacon. When enabled, the LEDblinks the internationally-recognized Morse Code “S.O.S.” message(•••–––•••) at a rate of 5 words per minute. This can be very useful insummoning help from rescuers who may not be able to communicate withyou 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 willflash the Morse Code S.O.S. message repeatedly.2. The S.O.S strobe will not operate if the squelch is turned off (Squelchmust 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 onagain.

CHANNEL ASSIGNMENTSTables on the following columns list the VHF Marine Channel assignmentsfor 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 Guard’sVessel Traffic System.2. Alpha channel numbers, that is, channel numbers followed by the letterA (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 assignedto U.S.A, and Canadian Coast Guards for handling distress and othercalls. 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 theCoast Guard. To use Channel 22A, your radio must be set for USA orCanada 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 notindicated 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 bridgeoperators on intercoastal waterways and rivers. It is also used by marinevessels in the vicinity of these bridges for navigation and for communi-cating with the bridge operators. Note that a limit of 1 Watt is specifiedfor 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. Onlyone 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
