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.
GPS Operation
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 L
O 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.
