Problem
Things to Try
I can’t read the display.
Adjust the contrast and backlight brightness level
(see page 23)
The display is too bright at
night.
Adjust the backlight brightness level.
Turn off the radio; hold menu key and turn it back
on (see page 23)
I can’t see any words on the
display.
Reset the radio back to the default brightness
level: turn off the radio; hold the menu key 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).
Make sure your GPS receiver is working properly.
Make sure that your GPS receiver supports the
NMEA parameters described in NMEA Operation
on page 67.
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
include your current location (see Using FIPS
codes for weather alerts on page 21).
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 21).
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 radio triggers the alert tone and switch-
es to the weather channel when this happens.
I can’t make Group DSC
calls.
Make sure the Group MMSI was entered cor-
rectly.
Where can I find my radio’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 enter
my User MMSI. What do I
do?
Contact customer service.
