NOISE
Electrical noisepicked upbythepower cablecan beminimizedby

One
of the largestnoise
generators is theengine's wiring harneth that runs
from theenginetothe instrument

wirefor thetachometerwhichradiatesRF(radio frequency)energy. For
bestresults,keepthe

VHF radio antennacables radiateRE energyathigher power levels

tokeep theX-5's

antennacable.
Ifthereisnonoise—interference—ontheunitwhentheboatissitting

thena
