l evel is adequate,the backg r ound noise does not
p re s e nt a serious pro b l e m .Al s o,when ext re m e l y
l ow level signals are being re ce i ve d ,the tra n s ce i ve r
m ay be ope rated with vehicle engine turned off.

i te r ,in some installations ignition inte rfe re n c e may
be high enough to make good co m m u n i cat i o n s

radio technician for help in locating and co rre ct i n g
the source of seve re noise.
