Uniden UM425 VHF DSC 사용자 설명서

Interference from the noise generated by the electrical systems of engines 

is sometimes a problem with radios. The UM425 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. The UM425 radio 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.
