the receiver top panel provides a
fixed-level line output and an adjusta-

put.
The output jack is wired as follows:

headphone amplifier, do not con-
nect headphones with an imped-
ance lower than 16 Ω to the head-
phone output.

level of the headphone output (2).
The color of the volume control knob
indicates the receiving frequency of
your receiver.
RF LED: Indicates the field strength
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
channel than the transmitter) or the
received signal is muted because the
squelch is engaged.
LED does not light: power to the
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.
