Troubleshooting

If you encounter a problem using this transmitter, use the following checklist to find a solution. For any problems with the 
receiver or adapter, refer to the operating instructions supplied with the respective device. If the problem persists, consult 
your Sony dealer.

Symptom

Meanings

Remedy

The transmitter does not 
turn on.

The batteries are inserted backwards in the 
battery compartment.

Reinsert the batteries with the correct orientation 

(see page 5)

.

The batteries are exhausted.

Replace the batteries with new ones.

The power is repeatedly 
turned ON/OFF (screen 
turns on/off) even when 
the POWER switch is 
ON.

The batteries are exhausted.

Replace the batteries with new ones.

The batteries drain 
quickly.

Manganese batteries are being used.

Use alkaline batteries.

The transmitter is being used under cold 
conditions.

The batteries drain quickly under cold conditions.

Interruptions in the 
reception occurs.

The transmitter is too far from the receiver.

Decrease the distance to the receiver and check 
the reception. 

The transmission power setting is set to “L”.

Increase the transmission power 

(see page 12)

.

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 setting of the encrypted transmission 
function on the receiver is different from that on 
the transmitter.

Confirm that the setting of the encrypted 
transmission function is the same on both the 
transmitter and the receiver 

(see page 8)

.

The audio codec mode settings on the receiver 
and transmitter do not match.

Configure the same audio codec mode setting for 
both the receiver and transmitter 

(see page 12)

.

The sound is weak. 

The audio input level of the transmitter is set to 
LINE or the attenuation level is too high. 

If a microphone is connected to the transmitter, set 
the audio input to MIC 

(see page 12)

. While 

monitoring the audio input level meter, set the 
attenuator to an appropriate level.

There is distortion in the 
sound. 

The attenuator is set too low for the audio input 
level of the transmitter. 

While monitoring the audio input level meter, set 
the attenuator to a level that does not produce 
distortion.

The bass is weak.

The frequency of the low-cut filter is set too 
high.

While monitoring the sound, decrease the low-cut 
filter frequency to a level that produces the proper 
sound quality 

(see page 10)

.

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 

(see page 10)

.

The power does not turn 
off even though the 
POWER switch is turned 
to OFF.

The POWER switch is locked.

Turn off the LOCK function 

(see page 11)

.

Wireless remote control 
is not possible.

Pairing has not been established between the 
transmitter and receiver.

Carry out pairing 

(see page 7)

.

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 

(see page 5)

.

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 display is too dark.

The display brightness is set to low.

Adjust the brightness of the displa

(see page 13)

.

The RF output power 
cannot be configured.

The maximum RF output power function may be 
set to limit the RF output power.

Check and adjust the setting.
