Some tips to improve the performance of the system
The transmitter and antenna should be kept in the relative position of accessibility of the
straight line
Don’t put the receiver close to the metal surface or near any digital device (such as CD play-
ers, computer, etc.)
Try to place the receiver in height of 1.5 meters from the ground and the position of a dis-
tance of 1 meter away from the wall

Solutions
No sound or
weak voice
The transmitter’s display is
set off
Turn on the transmitter power. Confirm that the +/- marks on
the battery match with the head joint of the transmitter.
Insert new battery.
Receiver’s display is set off
Confirm whether a head of the AC power adapter is plugged
into the power outlet, and whether the other end is inserted
into the DC power supply socket on the rear panel of the re-
ceiver. Check whether the AC power outlet is normal and
confirm whether the power supply voltage is normal.
The display screen of the re-
ceiver shows that there is no
RF signal
Rise the receiver’s volume control. Check the cable connec-
tion between the receiver and the amplifier or mixer.
The display screen of the re-
ceiver shows that there is no
RF signal. The transmitter
and receiver power indica-
tors light.
Elongate vertically the receiver’s antenna.
Move the receiver away from side of the metal objects.
Check if there are obstacles between the transmitter and the
receiver.
Move the transmitter closer to the receiver.
Check whether the receiver and transmitter are using the
same frequency.
Remove the interference source nearby (such as CD players,
computers, digital devices, earplugs monitoring system, etc.)
