For optimum receiving please follow these instructions:
•
Maintain a line-of-sight between the transmitter and receiver antennas, if possible. Avoid placing
transmitter and receiver where metal or other dense materials may be present.
•
Avoid placing the receiver near computers or other RF generating equipment.
Adjust the signal output level via the Volume-control.
If the receiver is no longer used, please turn the Volume-control to 0 and switch the device off.
IMPORTANT: Every wireless microphone installation is a unique situation, and can present a variety of
problems. Never attempt a live performance without first conducting a test of the system in the performing
area. If major changes (additional wireless systems or intercoms, relocation of scenery, etc.) have been
made since the last test, check the wireless system again - as close to performance time as possible.

PROBLEM:
No power.
No sound; receiver RF-
LED does not flash.
No receiver sound;
receiver RF-LED flashes.
Received signal is noisy
or contains extraneous
sounds with transmitter
on.
Noise from receiver with
transmitter off.
Momentary loss of sound
as transmitter is moved
around performing area.
The Squelch-control is factory preset at the 12 o'clock position for optimum
performance. No further adjustment is normally required. However, it is possible
to adjust the squelch control to emphasize either signal quality or system range.
To raise the squelch threshold, rotate the control clockwise. This causes the
receiver to demand a higher quality signal (less noise before muting), but it
reduces the operating range. To lower the squelch threshold, rotate the control
counterclockwise. This allows a lower quality signal through (more noise before
Check the connection cable of the power unit and any extension-cables.
Make sure POWER switches on transmitter and receiver are on.
Check transmitter Power-LED to ensure that battery is providing power.
Replace battery if necessary.
Check receiver squelch setting.
Make sure that the receiver is in the line of sight of the transmitter. If
necessary, reduce the distance between transmitter and receiver.
Turn up the receiver audio output LEVEL control.
Check for proper connection between receiver and microphone mixer.
Talk into the microphone and observe the receiver RF-LED. If it flashes, the
problem is elsewhere in the sound system.
Check transmitter Power-LED to ensure that battery is providing power.
Remove local sources of RF interference, such as lighting equipment .
Two transmitters may be operating on the same frequency. Locate and turn
one off.
Signal may be too weak. If possible, move receiver closer to the transmitter.
Adjust receiver Squelch-control.
Adjust receiver Squelch-control.
Remove local sources of RF interference, such as lighting equipment.
Reposition the receiver.
Reposition receiver and perform another test and observe the RF-LED. If
audio drop-outs persist, mark these dead spots in the performing area and avoid
them during the performance.
