Problem Things to Try
I can’t see any words on
the display.
Reset the radio back to the default brightness level: turn
off the radio; hold the CALL-MENU button and turn it
back on.
I’m not getting any GPS
data on my display.
Make sure your GPS receiver is correctly connected
(see Connecting to a GPS receiver, page 35).
Make sure your GPS receiver is working properly.
Make sure that your GPS receiver supports the NMEA
parameters described in NMEA Operation on page 50.
I’m not getting any hazard
alerts.
Make sure Weather Alert Watch is turned on.
Check to make sure the FIPS codes in your radio in-
clude your current location (see Using FIPS codes for
weather alerts on page 19).
I’m getting all the hazard
alerts, not just the ones for
my area.
Check to make sure the FIPS codes in your radio were
entered correctly (see Using FIPS codes for weather
alerts on page 19).
Sometimes the Weather Alert Watch may catch a
hazard alert in the middle of the broadcast and miss
which FIPS codes are affected. For your safety, the ra-
dio triggers the alert tone and switches to the weather
channel when this happens.
I can’t make Group DSC
calls.
Make sure the Group MMSI was entered correctly.
Where can I nd my ra-
dio’s serial number?
Look on the right side of the radio (the side with the
microphone cord), behind the mounting bracket.
The radio won’t let me en-
ter my User MMSI. What
do I do?
Contact customer service.
I keep hearing an alert tone
every few hours.
You are connected to a GPS but not receiving coordi-
nates. Check your GPS unit to be sure it is connected
properly. If the GPS is not functioning properly, discon-
nect it; the tones will stop.
Engine Noise Suppression
Interference from the noise generated by the electrical systems of engines is sometimes a
problem with radios. Your radio has been designed to be essentially impervious to ignition
noise and alternator noise. However, in some installations it may be necessary to take
measures to further reduce the effect of noise interference. Your radio’s DC battery wires,
antenna lead, and accessory cables should be routed away from the engine and engine
compartment, and from power cabling carrying high currents. In severe cases of noise
interference, it may be necessary to install a noise suppression kit. Contact the dealer where
you purchased the radio for more information.
