The AF/PEAK indicator is lit in
red.
The audio input of the transmitter has
exceeded the peak level.
Change the audio input attenuator of the
transmitter so that the input level does not exceed
the peak. The wireless remote function can be
used to change the setting from the receiver (see
page 30) .
The battery indication is flashing. The batteries of the transmitter will run
out of power soon.
Replace the batteries of the transmitter.
The number of lit indications of the
QL meter has reduced.
The signal input level of the antenna
has become low or the quality of the
reception signal has become low
because of interfering radio waves
(interference).
(1) If the RF indicator is lit in red or off, the signal
input to the antenna may be insufficient.
• Check the transmission power setting of
the transmitter.
• Check the receiving antenna, each device
between the receiver, cable connections,
and settings.
• Reduce the distance between which the
transmitter and receiving antenna are
used.
(2) If the number of lit indications of the QL meter
has reduced even though the RF indicator is
lit green, there may be interference.
• Check whether there is a problem with the
operation channel plan.
• Check whether another external signal is in
use.
The RF indicator is lit in orange. The signal input level of the antenna is
80 dB
µ
or higher.
Multi-channel synchronous operation may be
affected. Try one of the following.
• Try using the transmitter located away from the
antenna.
• Increase the ANT ATT a/b setting value of the
receiver. If the ANT ATT a/b setting value is
increased, be sure to also check the
transmission distance limit between the
transmitter and receiver.
The RF indicator is lit in red or off. The signal input level of the antenna is
barely enough for reception or
reception is not possible.
• Check the transmission power setting of the
transmitter.
• Check the receiving antenna, each device
between the receiver, cable connections, and
settings.
• Reduce the distance between which the
transmitter and receiving antenna are used.
The key icon is flashing on the
audio input level meter.
The encrypted transmission settings on
the transmitter and receiver do no
match.
Set the encrypted transmission settings on the
transmitter and receiver so that they match (see
page 26) .
“EXT” flashes on the digital output
sync indication.
The output signal from the DIGITAL
OUT connector is not synchronized to
the external synchronization word
clock.
• Check whether the synchronization signal input
is connected properly.
• Check whether the synchronization signal
conforms to the specifications of the receiver.
