OPERATION
Turn off the system first, turn down the receivers volume to the minimum and then turn on the receiver, CPU initializes, the LCD
screen begins to display and the system reverts to the last shutdown's state!
If the system is turned on look at the transmitter and receiver's frequency.Then the receiver display shows RF signal level value,
the antenna status will display antenna A or B. Adjust the volume to the desired level.
Volume adjustment
Adjust the receiver's volume to the 12 o'clock position, then adjust the volume of the amplifier or mixer to a desired level. If the
receiver volume has been adjusted too loud the amplifier will produce a saturated distortion which will blow the amplifier or/and
the loudspeaker(s)!
Best acoustics:
1. You should always see the receiver antenna from your transmitter location.
2. The distance between transmitter and receiver should be as short as possible.
3. If the receiver has two antennas, they should be adjusted 45° with a vertical line.
4. Keep the antennas away from metal surfaces and shelter.
5. Let the antennas not contact or cross each other.
6. Before using the system during the presence of public do a test to find out where the "dead spots" are. Avoid these
spots when operational

SOLUTION
Slide transmitter POWER ON/OFF
switch to ON position. Make sure battery
is inserted properly, observing battery (+
/ -). If battery is inserted properly,
replace with fresh battery.
Slide transmitter MUTE/ON switch to
ON position.
Make sure AC adapter is securely
plugged into electrical outlet and into DC
input connector.
Make sure AC electrical outlet works
and supplies proper voltage.
Turn up receiver volume control.
Confirm that the output connections
from the receiver to the external
equipment are secure.
Adjust transmitter gain level to
compessary.
Adjust receiver volume as necessary.
Replace transmitter battery
Identify potential sources of
interferences (other RF-sources) and
turn off, remove or use a wireless
system operating on a different
frequency.
Reposition receiver and perform walk-
through test again. If audio dropouts
persist, mark "dead" spots and avoid
them during performance.
