FM Modulator
Connections
and
Installation
Instructions
NOTE
1. The Vehicle antenna is cut off from the radio when
the power is supplied to the FM modulator via SW1.
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 cause unwanted noise.
Reducing higher level inputs can be achieved through
the use of special attenuators or line level reducers.)
3. SW2 is used to select the modulator frequency. The
radio must be turned to the same frequency that was
selected by Switch SW2.
