Troubleshooting
There is too 
much bass.
The microphone connected to 
the transmitter produces 
excessive bass because the 
frequency response of the 
transmitter extends into the low 
20-Hz range.
Use the low-cut filter to cut the 
bass.
The power 
does not turn 
off even though 
the power 
switch is turned 
to OFF.
The power switch is locked.
Turn off the POWER SW LOCK 
function.
Wireless 
remote control 
is not possible.
Pairing has not been established 
between the transmitter and 
receiver.
Carry out pairing (see page 26).
The receiver is too far from the 
transmitter for communication to 
occur.
Check the wireless remote control 
condition level. If it is low, 
decrease the distance between 
the transmitter and the receiver.
The transmitter that was paired 
with the receiver has been 
paired with another receiver.
On the receiver, carry out pairing 
again with the transmitter that you 
want to control.
The USB 
keyboard does 
not work.
You are using a USB keyboard 
that is not compatible with the 
transmitter.
Check the conditions for using a 
USB keyboard with the transmitter 
(see page 30).
The display is 
too dark.
The display brightness is set to 
low.
Adjust the brightness of the display 
(see page 35).
