Wireless System Trouble Shooting 

If   you   happen   to   encounter   any   problems   while   using   your   wireless   system,   it’s   recommended   that   this
trouble shooting section is checked to see if a solution can be found. If none of the suggested solutions
included below solve your particular problem, please contact your local retailer for further advice.

This trouble shooting section includes all of the most common possible issues and is not a complete list of
every  possible  fault,   defect,  and  their  subsequent  solution. This  section  is generally  focussed  on  solving
problems regarding the use of wireless systems. It may be that some of the included problems, causes, and
solutions do not apply to your situation since product specifications can differ.

Problem

Common cause

Solution

Transmitter is not switching 
on

Power socket not active

Check that the mains power socket is 
active, especially if it is (for example) a 
power block with a switch or a power 
switching system fitted with power sockets.

Power supply is not securely 
connected

Check that the power supply is securely 
connected to the receiver and that the plug 
is securely connected to an active mains 
power supply socket.

Power button has not been 
pressed

Make sure that the power button of the 
transmitter has been pressed.

Receiver is not switching on  No batteries

Check that batteries have been installed in 
the battery compartment.

Batteries incorrectly installed 

It might be that the batteries have been 
installed the wrong way around. Always 
ensure that the batteries are installed so 
that the polarity (+/-) matches the polarity 
indicated in the compartment.

Batteries empty/low

Replace the batteries with new, high-quality 
batteries.

No sound

Volume is too low

Turn the transmitter volume up and check 
that the audio signal strength indicator is 
active. 

Mixer channel is muted or 
incorrectly set

Check the basic PA mixer controls like the 
mute switch, master volume level, trim or 
gain level, master volume, EQ control 
settings etc. 

Transmitter is not linked to 
receiver

Make sure that the receiver is actively 
coupled with the transmitter by following the
instructions included in this manual.

Signal interference or drop-
out

Transmitter position is not 
optimum

Where possible, always ensure that the 
transmitter is positioned so it can achieve 
the best possible ‘line of sight’ of the 
bodypack receiver. 

Transmitter is placed too far 
away from receiver

If the receiver is more than 10 metres away 
from the transmitter, this can cause a break 
in the signal since the signal from the 
transmitter can no longer reach the receiver.
Check the Hi and Lo Power indicator and 
change to Hi to strengthen the signal 
transmission.
