18 On/Off Switch:
This slide switch provides three positions labeled
as follows:
ON:
Power to the transmitter is on.
MUTE:
The signal delivered by the microphone or instrument is
muted while power and the RF carrier frequency remain on.
This prevents the receiver from responding to interference from
other transmitters.
OFF:
Power to the transmitter is off.
19 Status LED:
Indicates battery status.
LED flashes momentarily upon switching ON and extinguishes:
batteries are OK.
LED lights constantly: batteries will be dead in about 50 minutes.

3-pin mini XLR connector with both mic and line
level pins that automatically match the connector pinout of the
recommended AKG microphones or optional MKG/L guitar cable.

for fixing the transmitter to your belt.
23 Battery Compartment Lid:

phone level (“MIC” position) or line level (“LINE” position).
25 GAIN:
This rotary pot matches the sensitivity of the transmitter’s
audio section to the level of the connected microphone or instru-
ment.
26 Carrier Frequency Label:
The label on the transmitter rear panel
indicates the carrier frequency, color code (receivers with the same
carrier frequency are marked with the same color), and approval
marks of your transmitter.

AKG microphones:
