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 vessel’s name, your vessel’s name, your vessel’s name”.
2. Then repeat once: “Mayday, your vessel’s 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.

SX 35 DSC
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.
SX 35 DSC
9
Call the marine operator and identify yourself with your vessel’s 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.
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 ma- rine 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 vessel’s 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.

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 transceiver’s 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.
