26 Troubleshooting
Meanings
The microphone connected to
the transmitter produces
excessive bass because the
frequency response of the
transmitter extends into the low
20-Hz range.
The POWER switch is locked.
Pairing has not been established
between the transmitter and
receiver.
The receiver is too far from the
transmitter for communication to
occur.
The transmitter that was paired
with the receiver has been
paired with another receiver.
You are using a USB keyboard
that is not compatible with the
transmitter.
The display brightness is set to
low.
Remedy
Use the low-cut filter to cut the
bass (see page 20).
Turn off the POWER SW LOCK
function (see page 21).
Carry out pairing (see page 12).
Check the wireless remote control
condition level. If it is low,
decrease the distance between
the transmitter and the receiver
(see page 9).
On the receiver, carry out pairing
again with the transmitter that you
want to control.
Check the conditions for using a
USB keyboard with the transmitter
(see page 16).
Adjust the brightness of the display
(see page 22).
