Troubleshooting
If you have any problem, use the following checklist before asking for repairs. If the problem persists, contact your Sony
service representative.
Symptom
Cause
Solution
The unit does not turn
on.
The
3
and
#
polarity orientation of the batteries is
incorrect.
Insert the batteries with the correct polarity
orientation.
The batteries are getting low.
Replace the batteries with new ones.
The battery terminals are dirty.
Clean the
3
and
#
terminals with a cotton swab.
Batteries are not inserted despite PWR SOURCE
being set to BATT ONLY.
Insert batteries, or change the PWR SOURCE
setting.
There is no sound.
The channel setting on the transmitter is different
from that on the receiver.
Use the same channel setting on both the
transmitter and receiver.
The compander mode setting on the transmitter is
different from that on the receiver.
Use the same compander mode setting on both
the transmitter and receiver.
The sound is
distorted.
The channel setting on the transmitter is different
from that on the receiver.
Use the same channel setting on both the
transmitter and receiver.
The sound is weak.
The supplied cables and connected device are not
connected properly.
Refer to the operating instructions of the
connected device, and perform proper
connections.
There is sound
interruption or noise.
Two or more transmitters are set to the same
channel.
Two or more transmitters cannot be used on the
same channel. Refer to the frequency list stored
on the supplied CD-ROM, and reconfigure the
channel on each transmitter.
The transmitters are not set to the channels within
the same channel group.
The channel plan is set so that no signal
interference occurs when two or more transmitters
are used simultaneously. Set each transmitter to a
different channel within the same channel group.
Adjacent channels are being used.
Use the channels separated by at least two
channels (250 kHz).
Jamming radio waves are being received.
Set the channel on the receiver to a channel for
which the RF indicator does not light, or use the
Clear Channel Scan function to switch to a
channel without interference. Then, set the
transmitter to the same channel as the receiver.
If using two or more transmitters, change to a
channel group that is not affected.
The RF indicator on
the receiver lights up
even when the
transmitter is off.
Jamming radio waves are being received.
Set the channel on the receiver to a channel for
which the RF indicator does not light, or use the
Clear Channel Scan function to switch to a
channel without interference. Then, set the
transmitter to the same channel as the receiver.
If using two or more transmitters, change to a
channel group that is not affected.
The transmitter
channel cannot be set
with infrared
transmission.
The infrared receptor on the transmitter is too far
from the infrared transmission port on the receiver.
Reduce the distance between the infrared receptor
on the transmitter and the infrared transmission
port on the receiver to within about 20 cm (8 in.).
Interference from infrared communications
between other devices or from direct sunlight is
present.
The transmitting distance is reduced when
interference from strong sunlight, for example, is
present. Place the transmitter and receiver as
close to each other as possible.
