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 31).

Make sure your GPS receiver is working properly.

Make sure that your GPS receiver supports the 

NMEA parameters described in NMEA Operation 

on page 46.

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 15).

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 15).

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 safe-

ty, the radio 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 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.

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.
