GPS Operation

DSC Monitor must be on for radio to receive calls

NOTE

DSC calls will NOT be received when the radio is receiving or sending out a transmission. During scanning, Ch. 70 is monitored on an allocated time-slot basis and DSC calls will be received.

Your radio is NMEA 0183 compatible, which means it can work with a GPS unit. To be certain your location is autom+atically transmitted during a distress call, make sure your GPS unit is on and operational at all times. The GPS data is sent through Ch. 70 to the coast guard and is the primary starting point of any search and rescue mission. If THE GPS ANNUNCIATOR is blinking, the GPS data is not valid.

H/L

The H/L key gives you control over the radio's wattage. The high-end is 25 Watts. The low-end is 1 Watt. If the LO ANNUNCIATOR is off, the radio will transmit at 25 Watts. Some channels do not accept transmissions or are restricted to a 1-Watt level. If you come across one of those chan- nels and you try to switch to 25W, you will hear a 3-tone error beep, meaning you either can not transmit on that channel or it only accepts transmissions at the 1W (Lo) level.

Memory Operation

Normally, the MEM ANNUNCIATOR appears on the display to alert the user the channel is stored in the memory channel list. The following figure shows Ch. 8 is stored in memory.
