BASIC RADIO COMMUNICATION PROCEDURES
Distress or emergency calls may be made either manually or automatically. Sending distress calls automatically uses the Digital Selective Calling (DSC) functions of your transceiver and requires an operating and properly connected navigation receiver. The following procedures are for sending voice distress messages manually. Sending an automatic distress call is described in the DSC section of this manual. Using Channel 16 Channel 16 is the Calling and Distress channel. An emergency may be defined as a situation that threatens human life or property. In such situations, make sure your transceiver is turned On and set the channel selector to Channel 16. Then use the following procedure to make a distress call. The total transmission should not exceed 1 minute. 1. Press the microphone Push To Talk button. Speak slowly and clearly into the microphone: Mayday, Mayday, Mayday, this is your vessels name, your vessels name, your vessels name. 2. Then repeat once: Mayday, your vessels name. 3. Continue by reporting your position in latitude and longitude or by reporting your bearing (true or magnetic, specify which) and distance from a prominent or well known landmark, geographic feature or aid to navigation. 4. Explain the nature of your emergency (fire, sinking, collision, grounding, health condition, injury, etc.). 5. Report the kind of assistance you require (fire, medical aid, pumps, etc.). 6. State the number of people aboard and the condition of any injured. 7. Estimate the seaworthiness and condition of your vessel. 8. Describe your vessel: length, type, color and any distinguishing feature. 9. End the message by saying Over. Release the Push To Talk button and listen for a reply. 10. If there is no reply, repeat the above message procedure. If there is still no response, try another channel.

Calling Another Vessel Channel 16 may be used to establish initial contact with another vessel. However, its most important use is for voice emergency messages. Channel 16 must be monitored at all times except when engaged in actual communication on another channel. Channel 16 is monitored by international search and rescue (SAR) authorities, National Coast Guards and by other vessels. Use of Channel 16 for calling or hailing must be limited to initial contact only. Calling should not exceed 30 seconds and may be repeated 3 times at 2 minute intervals. Prior to making contact with another vessel, determine which channel will be used for continued communication after the initial contact. Channels 68 and 72 (see Channel Assignment tables) are two channels available for noncommercial (recreational) communication. Monitor the desired channel for traffic and, when clear, switch to Channel 16 to make initial contact. Listen for traffic on the Calling Channel (16). If clear, press the Push To Talk (PTT) button on the microphone. Speak the name of the vessel you are calling followed by this is and the name of your vessel and your call sign. Release the PTT and listen for a reply. When the other vessel returns your call, acknowledge the call with go to, the number of the new channel and over. Switch to the new channel and listen for traffic. If necessary, wait for traffic to clear, and then call the other vessel. As communication proceeds, end each transmission with over. When communication with the other vessel is completed, end the last transmission with your call sign and the word out. It is not necessary to end each transmission with your call sign, just give your call sign at the beginning and end of each contact. Remember to switch to Channel 16 when not actively communicating on another channel. Telephone Calls You may use your SX 35 DSC transceiver to make telephone calls to persons on shore. To do so requires the services of marine operators who operate on designated Public Correspondence channels. There are several channels designated for this type of traffic and to determine the channel being used in your area, ask someone with local knowledge, contact a Harbor Master or other marine authority.
Call the marine operator and identify yourself with your vessels name. Normally you contact a marine operator on their working channel rather than making initial contact on Channel 16. The marine operator will ask for your intentions and establish a payment method for the call (collect, credit card, etc.). When arrangements are complete, your radio communication will be patched into the telephone line. In conversing with a person on the phone it is important to use normal radio communication procedures. You should say over and release the PTT button at the end of each transmission. Both parties cannot speak simultaneously as on normal telephone calls. Usually there is a fee for marine operator services which is charged in addition to any other charges associated with the call. Prohibited Communication The following communications are prohibited by regulations and violators are subject to penalties. False distress or emergency messages (including false DSC distress). Messages to any vessel except in emergencies and radio tests. Messages to or from a vessel on land. Transmission while on land. Obscene, indecent, or profane language.

INSTALLATION

Transceiver Your SX 35 DSC Transceiver is designed to withstand the rigors of the marine environment. However, selecting a mounting location affording some protection from the elements will prolong the life of connectors, controls and the liquid crystal display (LCD). Select a location within easy reach and view of the operator and away from your vessels compass. Locate the microphone to avoid entanglement with steering or engine controls, both when in use and when stowed. Also, consider routing of antenna, power and NMEA interface cables. Mount the transceiver securely to a solid surface. Antenna Proper installation of a quality VHF antenna is very important to reliable radio communication. A good quality unity gain antenna is recommended for maximum range performance. In general, antennas should be located as high as practical and separated as much as possible from other antennas and structures. The minimum distance to other objects is 1 meter. Route the antenna cable away from other electronic equipment and do not bundle the antenna or power cable with other wiring, especially transducer cables for depth sounders and fish finders. For cables longer than 10 meters, RG8/U coaxial cable must be used. Mount the antenna and install the connector(s) in accordance with manufacturers instructions. Connect the antenna cable to the RF output connector on the rear panel of the transceiver. Power Connection CAUTION Reverse polarity connections can damage your transceiver The power cable for you transceiver must be connected to the ships main power buss. Use the 6.3 Amp in-line fuse provided. Connect the Red wire to the positive (+) terminal and the Black wire to the negative () terminal. Connect the barrel terminals on the power cable to the matching color wires and terminals extending from the rear panel of the transceiver.
NMEA Cable In order for the position reporting features of your SX 35 DSC transceiver to function, an operating GPS navigation receiver must be connected to your transceiver. The supplied data cable plugs into the 8 pin connector on the transceivers rear panel and the other end connects to the NMEA data output from your GPS navigation receiver. Your GPS must output the $GPRMC NMEA data sentence. Refer to your navigation receiver manual for information about its NMEA output settings and connections. External Speaker Connection Provision for connecting and external speaker is provided on the rear panel. Use an 8 Ohm speaker rated for at least 3 Watts and suitable for the environment at the chosen location. Rear Panel Connectors

Sending distress calls automatically uses the Digital Selective Calling (DSC) functions of your transceiver and requires an operating and properly connected navigation receiver. The following procedures are for sending voice distress messages manually. Sending an automatic distress call is described in the DSC section of this manual. Using Channel 16 Channel 16 is the Calling and Distress channel. An emergency may be defined as a situation that threatens human life or property. In such situations, make sure your transceiver is turned On and set the channel selector to Channel 16. Then use the following procedure to make a distress call. The total transmission should not exceed 1 minute. 1. Press the microphone Push To Talk button. Speak slowly and clearly into the microphone: Mayday, Mayday, Mayday, this is your vessels name, your vessels name, your vessels name. 2. Then repeat once: Mayday, your vessels name. 3. Continue by reporting your position in latitude and longitude or by reporting your bearing (true or magnetic, specify which) and distance from a prominent or well known landmark, geographic feature or aid to navigation. 4. Explain the nature of your emergency (fire, sinking, collision, grounding, health condition, injury, etc.). 5. Report the kind of assistance you require (fire, medical aid, pumps, etc.). 6. State the number of people aboard and the condition of any injured. 7. Estimate the seaworthiness and condition of your vessel. 8. Describe your vessel: length, type, color and any distinguishing feature. 9. End the message by saying Over. Release the Push To Talk button and listen for a reply. 10. If there is no reply, repeat the above message procedure. If there is still no response, try another channel.
Calling Another Vessel Channel 16 may be used to establish initial contact with another vessel. However, its most important use is for voice emergency messages. Channel 16 must be monitored at all times except when engaged in actual communication on another channel. Channel 16 is monitored by international search and rescue (SAR) authorities, National Coast Guards and by other vessels. Use of Channel 16 for calling or hailing must be limited to initial contact only. Calling should not exceed 30 seconds and may be repeated 3 times at 2 minute intervals. Prior to making contact with another vessel, determine which channel will be used for continued communication after the initial contact. Channels 68 and 72 (see Channel Assignment tables) are two channels available for noncommercial (recreational) communication. Monitor the desired channel for traffic and, when clear, switch to Channel 16 to make initial contact. Listen for traffic on the Calling Channel (16). If clear, press the Push To Talk (PTT) button on the microphone. Speak the name of the vessel you are calling followed by this is and the name of your vessel and your call sign. Release the PTT and listen for a reply. When the other vessel returns your call, acknowledge the call with go to, the number of the new channel and over. Switch to the new channel and listen for traffic. If necessary, wait for traffic to clear, and then call the other vessel. As communication proceeds, end each transmission with over. When communication with the other vessel is completed, end the last transmission with your call sign and the word out. It is not necessary to end each transmission with your call sign, just give your call sign at the beginning and end of each contact. Remember to switch to Channel 16 when not actively communicating on another channel. Telephone Calls You may use your SX 35 DSC transceiver to make telephone calls to persons on shore. To do so requires the services of marine operators who operate on designated Public Correspondence channels. There are several channels designated for this type of traffic and to determine the channel being used in your area, ask someone with local knowledge, contact a Harbor Master or other marine authority.

Call the marine operator and identify yourself with your vessels name. Normally you contact a marine operator on their working channel rather than making initial contact on Channel 16. The marine operator will ask for your intentions and establish a payment method for the call (collect, credit card, etc.). When arrangements are complete, your radio communication will be patched into the telephone line. In conversing with a person on the phone it is important to use normal radio communication procedures. You should say over and release the PTT button at the end of each transmission. Both parties cannot speak simultaneously as on normal telephone calls. Usually there is a fee for marine operator services which is charged in addition to any other charges associated with the call. Prohibited Communication The following communications are prohibited by regulations and violators are subject to penalties. False distress or emergency messages (including false DSC distress). Messages to any vessel except in emergencies and radio tests. Messages to or from a vessel on land. Transmission while on land. Obscene, indecent, or profane language.

INSTALLATION

Transceiver Your SX 35 DSC Transceiver is designed to withstand the rigors of the marine environment. However, selecting a mounting location affording some protection from the elements will prolong the life of connectors, controls and the liquid crystal display (LCD). Select a location within easy reach and view of the operator and away from your vessels compass. Locate the microphone to avoid entanglement with steering or engine controls, both when in use and when stowed. Also, consider routing of antenna, power and NMEA interface cables. Mount the transceiver securely to a solid surface. Antenna Proper installation of a quality VHF antenna is very important to reliable radio communication. A good quality unity gain antenna is recommended for maximum range performance. In general, antennas should be located as high as practical and separated as much as possible from other antennas and structures. The minimum distance to other objects is 1 meter. Route the antenna cable away from other electronic equipment and do not bundle the antenna or power cable with other wiring, especially transducer cables for depth sounders and fish finders. For cables longer than 10 meters, RG-8/U coaxial cable must be used. Mount the antenna and install the connector(s) in accordance with manufacturers instructions. Connect the antenna cable to the RF output connector on the rear panel of the transceiver. Power Connection CAUTION Reverse polarity connections can damage your transceiver The power cable for you transceiver must be connected to the ships main power buss. Use the 6.3 Amp in-line fuse provided. Connect the Red wire to the positive (+) terminal and the Black wire to the negative () terminal. Connect the barrel terminals on the power cable to the matching color wires and terminals extending from the rear panel of the transceiver.

NMEA Cable In order for the position reporting features of your SX 35 DSC transceiver to function, an operating GPS navigation receiver must be connected to your transceiver. The supplied data cable plugs into the 8 pin connector on the transceivers rear panel and the other end connects to the NMEA data output from your GPS navigation receiver. Your GPS must output the $GPRMC NMEA data sentence. Refer to your navigation receiver manual for information about its NMEA output settings and connections. External Speaker Connection Provision for connecting and external speaker is provided on the rear panel. Use an 8 Ohm speaker rated for at least 3 Watts and suitable for the environment at the chosen location. Rear Panel Connectors
Antenna Connector The transceiver is fitted with a type SO 239 female connector which mates with a PL 259 male connector supplied with VHF marine antennas.

OPERATING PROCEDURES

Primary Calling Channel VHF Channel 16 (156.8 MHz) is the Distress Safety and Primary Calling Channel. All vessels, not actively engaged in communication, are required to maintain a listening watch on Channel 16. Transmitting The transmitter is activated, for normal voice communications, by pressing the Push To Talk (PTT) button on the microphone. Always listen for moment on a channel before transmitting. If the channel is busy, do not transmit until the channel is clear. For DSC calling and Distress calls, the transmitter is activated automatically during the appropriate operating procedure. After DSC contact is established, proceed as in normal voice communication. Continuous transmitter operation is limited to five minutes and the transmitter will automatically stop. To establish normal voice communication: Press the 16 key to select the Primary Calling Channel. The Primary Calling Channel is 16. The Primary Calling Channel number appears in the upper left corner of the display. Listen on the Primary Calling Channel to make sure the channel is clear. Press the PTT button. Speak directly into the microphone in a normal tone of voice --clearly--distinctly. Say (name of vessel being called) THIS IS (your vessels name and call sign). Release the PTT button and listen for a reply. Once contact is made on the Primary Calling Channel, each vessel must switch to a working channel to continue conversation. Refer to the channel chart for proper usage. After communication is completed, each vessel must give its call sign or vessel name and switch to the Primary Calling Channel and resume listening watch.

Working Channel Recall Rather than using the SELECT knob or microphone keys to change channels, this feature allows quick switching between the last working channel and the current primary channel. To quickly switch between the last working channel and the Primary Calling Channel: Use the SELECT knob or microphone keys to select a working channel, such as channel 68. Press the 16 key momentarily. The current primary channel number appears in the channel number display. Press the 16 key again momentarily. The working channel number appears in the display. Each time the key is pressed, channel selection toggles between the primary channel and the working channel.
Transmitter Power Setting The transmitter has two power settings, 25 watts or 1 watt, which are indicated by HI or LO appearing in the upper line of the display. The normal power setting is HI for all channels where 25 watts is allowed. Use the 1 watt setting for communication with nearby vessels (bridge-to-bridge) or facilities (drawbridges). Press the HI/LO key to toggle transmitter power between 25 watts and 1 watt output. SPECIAL NOTE Channels 15 and 17 are restricted to 1 watt maximum power and will cause the error beep if the HI/LO key is pressed. Channel Scanning There are three channel scanning modes; Priority Scan, All Scan and Memory Scan. In the Priority Scan mode, Channel 16 is checked for activity every 2 seconds, even if, the scan is halted by traffic on a working channel. When scanning is halted by traffic, the scan pauses while the channel is active. Scanning resumes, after a brief delay when the channel is clear. If the PTT is pressed, in reply to a received signal, scanning is cancelled.
Priority Scan The Priority Scan function scans the Primary Calling Channel and the last selected working channel. To select Priority Scan: Press the SCAN key. PSCAN appears in the upper line of the display and the two scanned channel numbers appear alternately in the display.
