OPERATING INSTRUCTIONS (cont’d.)
6) A small screwdriver is supplied with the transmitter. The screwdriver is used to adjust the audio gain
of the transmitter to match your microphone and your voice. The GAIN ADJUST is located on the
side of the transmitter as shown on page 3. The adjustment is made while observing the modulation
level lamps on the receiver control panel:
a) Speak at the voice level you will be using during actual operation.
b) While speaking, adjust the transmitter gain until the green modulation lamp on the receiver (may
be marked "-20") is lit or flickers and the red modulation lamp blinks only on the loudest words.
Raise and lower your voice while observing the lamps. The red lamp should blink only
occasionally.
NOTE
The modulation lamps on some receivers are marked or colored differently than just
described. Consult the operating manual for the receiver in use.
7) You may now adjust the receiver output level (wireless microphone or mic volume, level, or volume
attenuator) to the desired audio output level. Consult your receiver manual if you are not sure of the
location of these controls.
The GAIN ADJUST is used only to adjust for proper modulation level lamp indications. DO NOT use it
to adjust the audio output level of the receiver. Different voices and different microphones will usually
require readjustment of the transmitter gain control, so check the adjustment frequently. If several
different people will be using the transmitter, and there is not time to make the adjustment for each
individual, adjust it for the loudest voice.
