Power to the modulator must be switched off in

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.
R educing higher level inputs can be achieved through
the use of special “attenuators” or line level reducers.)
