Notes on receiving  
performance  
This system utilizes very high frequency signals in the  
800 MHz band so the receiving performance may  
deteriorate due to the surroundings. The following  
examples illustrate conditions that may reduce the  
reception range or cause interference.  
Inside a building with walls containing steel beams.  
An area with many steel file cabinets, etc.  
An area with many electrical appliances capable of  
generating electromagnetic fields.  
The transmitter is placed on a metal instrument.  
An area facing a roadway.  
This process reduces noise picked up during  
transmission.  
Do not use rechargeable battery other than the  
supplied one.  
To recharge the headphone battery after use  
Place the headphones on the transmitter after use.  
Since the built-in timer recognizes when charging is  
complete, there is no need to remove the headphones  
from the transmitter after charging.  
Be sure to bring the headphones and the transmitter to  
the Sony dealer when requiring repair work.

About the charging method of the system  
This system employs a contactless charge method that  
requires no terminals by the electromagnetic induction.  
Sending RF signals from the transmitter  
The transmitter starts sending RF signals  
automatically when it detects an audio signal from the  
connected equipment.  
Do not expose batteries or apparatus with battery  
installed to excessive heat such as sunshine fire or the  
like.  
Polarity of the plug  
Notes  
If it does not detect an audio signal for more than  
about 4 minutes, the transmitter will stop sending RF  
signals, and the POWER/CHG indicator will turn off.  
When the transmitter receives an audio signal again, it  
starts sending the RF signals, and the POWER/CHG  
indicator will light up green again.  
If the audio signal is very weak, the transmitter does  
not send RF signals. If the transmitter is connected to a  
headphone jack, make sure the volume of the  
equipment connected is set to 5 - 6 or higher.  
You may not hear the beginning of the sound from the  
headphones until the transmitter starts sending the RF  
signals after detecting an audio signal.
