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.
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 24).
Make sure your GPS receiver is working properly.
Make sure that your GPS receiver supports the NMEA parameters described in NMEA
Operation on page 34.
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 10).
Check to make sure the FIPS codes in your radio were entered correctly (see Using
FIPS Codes for Weather Alerts on page 10).
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 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.
