level of the headphone output (2).
The color of the volume control knob
indicates the receiving frequency of
your receiver.

of the received signal:
LED lighting green: optimum field
strength.
LED lighting red: field strength is
zero (the transmitter is OFF or the
receiver has been set to a different

receiver is OFF, no batteries are in the
battery compartment, or the batteries
are dead.
AF LED: Indicates the received audio
level:
LED lighting green and flashing red
on peaks: optimum audio level.
