Inserting/replacing the battery
We recommend powering the microphone by a two 1,5V penlight alkali batteries.
 Turn the battery compartment cover counterclockwise and remove the cover.
 Insert the batteries as. Please observe correct polarity when inserting the batteries.
 Place the battery cover and gently turn the cover clockwise until the battery compartment is
closed.
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 (8) 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.
