Problem
I can’t hear anything (no
volume) from the speaker.
I can transmit, but no one
can hear me.
The display flashes, and I
don’t know why.
I can’t read the display.
The display is too bright
at night.
I can’t see any words on
the display.
I’m not getting any GPS
data on my display.
I’m not getting any hazard
alerts.
I’m getting all the hazard
alerts, not just the ones for
my area.
I can’t make Group DSC
calls.
Where can I find my
radio’s serial number?
The radio won’t let me
enter my User MMSI.
What do I do?
things to try
Adjust the squelch level; it is probably too high.
Check your UIC channel settings (see Setting the UIC channel mode
(USA/CAN/INT) on page 8).
The display will flash if the radio is in a watch mode or in scan mode.
Try turning off scanning, Weather Alert Watch, or Triple/Dual Watch
(see page 16.)
Adjust the contrast and backlight brightness level (see page 18)
Adjust the backlight brightness level.
Turn off the radio; hold
CALL-MenU
button and turn it back on (see
page 18)
Reset the radio back to the default brightness level: turn off the radio;
hold the CALL-MenU button and turn it back on.
Make sure your GPS receiver is correctly connected (see Connecting
to a GPS receiver, page 32).
Make sure your GPS receiver is working properly. Make sure that your
GPS receiver supports the NMEA parameters described in NMEA
Operation on page 45.
Make sure Weather Alert Watch is turned on.
Check to make sure the FIPS codes in your radio include your current
location (see Using FIPS codes for weather alerts on page 17).
Check to make sure the FIPS codes in your radio were entered cor-
rectly (see Using FIPS codes for weather alerts on page 17). Some-
times 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 radio triggers the alert tone and switches to the weather
channel when this happens.
Make sure the Group MMSI was entered correctly.
Look on the right side of the radio (the side with the microphone cord),
behind the mounting bracket.
Contact customer service.
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 meas-
ures 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 compart-
ment, 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.
