Receiver volume adjustement for the guitarist UHF.
1. Plug your instrument directly in the guitar/ bass amp. Set volume and tone controls on both the
instrument and amplifier for a clean signal with the desired tone and volume. Do not change
these setting for the rest of the volume adjustement.
2. Unplug instrument from the amplifier input and plug into the transmitter. Plug the receiver into the
amplifier input.
3. Adjust the receiver volume control until sound quality matches that achieved in step 1.
Transmitter audio gain adjustement.
The audio gain control has been factory set at the mid-range position for optimum perfeormance in most
applications. Ajustment may be nescesary for low output guitars.
 To increase the gain, rotate the transmitter gain control clockwise with a screwdriver .
 To reduce gain, rotate the transmitter gain control counterclockwise with a screwdriver.
To set the audio gain back to factory preset, rotate the transmitter audio gain control to the mid position.
Adjusting the squelch threshold.
Interference due to other transmission links can be eliminated as follows:
 Switch off the transmitter. The receiver should no longer receive a signal.
 If the receiver still receives a signal, use the squelch control (9) to increase the squelch threshold
so that the signal will no longer be received. If the signal cannot be eliminated in this wasy, set the
transmitter and the receiver to a different channel.
 Switch on the transmitter again and check if the receiver receives the transmitter signal.
Note:
If the squelch threshold is adjusted to high, the transmission range will be reduced. Therefore
always adjust the squelch control to the lowest possible setting.
Tips for achieving maximum performance.
 Make sure you can always see a receiver antenna from the transmitter position.
 Keep the distance from transmitter to receiver antenna as short as possible.
 Point the receiver antennas away from each other at 45 degrees angle from vertical position.
 Avoid placing the receiver antennas near metal surfaces and obstructions.
 Replace battery as soon as low battery LED lights.
 If stacking or rack mounting receivers in a multiple system setup. Do not allow antennas to cross.

Perform a walk-through before performance or presentation. If dead spots are found, adjust the
location of the receiver. If dead spots remain, mark the dead spots and avoid them.
