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 con- nected 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 Di

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. Chan- nel 16 must be monitored at all times except when engaged in actual com- munication 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 ex

Call the marine operator and identify yourself with your vesselÕs 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

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 vesselÕs compass. Locate the microphone to avoid entanglement with steering or engine controls, both when in use and when stowed. Als

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 transceiverÕs rear panel and the other end connects to the NMEA data out- put from your GPS navigation receiver. Your GPS must output the $GPRMC NMEA data sentence. Refer to your navigation receiver manual for infor- mation about its NMEA output settings and c
