INPUT JACK
The input on the M185 accommodates virtually every lavalier, hand-held or shotgun microphone
available. Use a Switchcraft TA5F connector on the cord. See the separate sheet titled "M185 Input
Jack Configuration" regarding the correct connections for various microphones, and other
sources.
ON/MUTE/OFF SWITCH
Turns the battery power on and off. The center position is an "audio mute" which should be used when
setting the MIC LEVEL control to turn off the sound from the microphone during this adjustment. When
turning the transmitter on, pause for a moment in the MUTE position to prevent a turn-on surge from
occurring (a "thump" sound) in the audio.
POWER ON/OFF LED
Glows brightly when battery is good. A weak or dim lamp means that the battery is weak, and has
about an hour of operation left (maybe a little more). If the lamp fails to light, the battery should be
replaced. The power lamp should light up in both the "mute" and "on" positions of the POWER/MUTE
SWITCH.
The POWER LED is connected to a precision battery test circuit that continuously monitors battery
voltage. The LED is at full brightness with a new 9 Volt alkaline battery. As the battery voltage drops
during use, the LED brightness will also decrease. After 12 to 15 hours the battery voltage will be
about 7 Volts and the LED will be completely out.
