the switch on the MS111 once to activate the microphone, press the switch again to mute
the microphone.
ASSIGNMENT SWITCH
The assignment switch is used to reverse the operation of the active switch. The MS111
ships from the factory set such that the microphone is on when the switch is in the UP
position and the mic is off when the switch is in the DOWN position. You can reverse this
if you wish so that the microphone is off when the switch is in the Up position and on when
the switch is in the DOWN position. To reverse the switch, nd the internal switch on the
right side of the MS111 as you are looking at it from the top. Simply move the internal
switch to the next position to reverse the operation of the active switch.
MOMENTARY OR LATCHING SWITCH OPTION
The active switch may be set to either latch the microphone in the On or Off position, or the
active switch may be changed so it functions as a Momentary switch. When functioning as
a Momentary switch the microphone is off only as long as you hold down the active switch.

following:
