LISTENING TO FM IN YOUR MARINE VEHICLE
The majority of FM broadcasts are music programs. Compared with AM signals,
FM signals have a wider dynamic range, are relatively immune to noise and
provide distortion-free reproduction.
FM programs are broadcast for local reception and may not be heard satisfactorily
at distant locations. To enjoy FM programs at their best, it is important that you
tune to a station that is broadcasting in your locality.
FM signals can reect from solid objects such as buildings or hills. If these
reected signals are received along with signals that are arriving directly from
the transmitter, they may mix together to produce what is known as ‘multipath
distortion. This distortion is heard as noise. Often, moving as little as 1 meter from
your position will correct this problem.
FM signals travel in straight lines. However, because the signals are reected from
or absorbed by large solid objects, a signal ‘shadow’ may be present behind the
object which may result in poor reception in that area.

INSTALLATION PRECAUTIONS
• If you are connecting your GR350BT radio for the rst time, or
have just reconnected your boat battery and you are experiencing
problems with the unit’s operation, we recommend you reset
the unit. The reset function is accessed through the Main MENU
