Problem
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 ra-
dio's serial number?
The radio won't let me en-
ter my User MMSI. What
do I do?
I keep hearing an alert tone
every few hours.

Things to Try
Check your UIC channel settings (see Setting the UIC
channel mode (USA/CAN/INT) on page 5).
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 5).
Adjust the contrast and backlight brightness level (see
page 14).
Adjust the backlight brightness level.
Turn off the radio; hold CALL-MENU button and turn it
back on (see page 14).
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 29).
Make sure your GPS receiver is working properly.
Make sure that your GPS receiver supports the NMEA
parameters described in NMEA Operation on page 43.
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 13).
Check to make sure the FIPS codes in your radio were
entered correctly (see Using FIPS codes for weather
alerts on page 13).
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.
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.
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.
