Engine Noise Suppression; Specifications; Radio Specifications - Uniden UM415BK Owner's Manual

Problem
The radio won't let me enter
my User MMSI. What do I
do?
Interference from the noise generated by the electrical systems of engines is sometimes a

engine noise suppression

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.
