1. The Vehicle antenna is cut off from the radio when
the power is s upplied to the F M modulator via S W1.
Power to the modulator must be switched off in
order to receive normal AM/FM reception.
2. The FM modulator is designed to accept “Line Level”
signals only. These “signals” require amplification to
drive headphones or speakers . (Inputting “Higher”
level audio signals (headphone, external speaker etc)
will override the radio and caus e unwanted noise.
R educing higher level inputs can be achieved through
the us e of special “attenuators” or line level reducers.)
3. S W2 is used to select the modulator frequency. The
radio must be turned to the s ame frequency that was
selected by S witch S W2.
