TROUBLESHOOTING
II. No audio present.
a. Using a DC Voltmeter, check the voltage across terminal “A” and “C” (”A” positive; “C” ground) of the Mic 3-Pin
Terminal Block[12]. It should read 12V. The microphone requires 12Vdc to work.
1) Check connections to the microphone.
b. Remove the wire connected to the “B” terminal of the Mic 3-Pin Terminal Block. Using an AC meter (set to
lowest voltage range), check the presence of audio from the microphone. Place the meter leads between wire
removed (positive) and terminal “C” (ground). Generate some loud noise close to the remote microphone
while observing the meter reading. If audio is present, the meter reading will start to fluctuate. If there is no
movement, the remote microphone is defective. Call factory for assistance.
Factory assistance is available between 8:30 AM to 4:00 PM Pacific time. Call (818) 994-6498.
