CONTROLS AND FUNCTIONS
EXTERNAL
“P” SWITCH – POWER ON/OFF
Audio Power
A slide switch which turns battery power on and off. The LED next to the switch lights up when the “P”
switch is turned on. This LED also serves as a battery condition indicator. The LED will glow brightly
when the battery is good and will dim as the battery condition deteriorates. The LED is at full brightness
with a new battery. When the battery voltage reaches 7 Volts, the LED will be completely dark. Note: this
LED will not light if the EXT LED switch is in the OFF position. On/Off On/Off
P A
“A” SWITCH – AUDIO ON/OFF
A slide switch which mutes the audio in the OFF position and allows the audio gain (modulation level) of the transmit­
ter to be adjusted without feedback from the sound system. This switch will do nothing if the EXTERNAL SWITCHES
switch is in the BYPASS position.
INTERNAL
FREQUENCY ADJUST SWITCHES
Two rotary switches adjust the center frequency of the carrier. The
switch closest to the windscreen is the fine adjustment, the other
one is the coarse adjustment. Each transmitter is factory aligned at
the center of its operating range. The default position of the fre­
quency select switches is in the center of the transmitter’s range.
The door is removed by pulling straight out with your fingernails.
MOD LEVEL LEDs
Frequency switches
located behind door.
These LEDs (loacted under the battery door) indicate the audio input level and are used
Mod Level
LEDs
when adjusting the transmitter AUDIO LEVEL (gain) control. As the audio level increases,
first one LED lights. The other LED lights as the audio level reaches maximum modulation.
The LEDs are located underneath the battery cover, next to the AUDIO LEVEL control and
are easily viewed when holding the transmitter in a normally used position.

AUDIO LEVEL CONTROL
This knob (also located underneath the battery door) is operated while speaking or singing into the transmitter to
adjust the audio gain of the transmitter for the correct amount of modulation. The LEDs located next to it indicate the
modulation level as the gain is adjusted. See page 6 for details on this very important adjustment.
EXTERNAL SWITCHES BYPASS
This concealed slide switch defeats the external switches on the bottom panel for applica-

tions where it is best that the user not be able to operate the power and mute switches. The

OFF
This slide switch defeats the battery status LED on the bottom panel for applications where
the LED may be distracting. With this switch in the right-hand position, the power will
remain on and the transmitter operating, even though the power LED is off. The external
LED is disabled when this switch handle is moved toward the bottom of the unit.
