NOTE:
You should then be able to move around freely from one room to another without
any interference. If interference does occur (interruptions in the signal), press
the "Auto Scan" button once to find a better reception channel.
A For better stereo reception, stay approximately seven meters away from
the transmitter when you press the "Auto Scan" button.
B If it is impossible to find a satisfactory frequency, change the setting on
your transmitter, then press the "Auto Scan" button on the headphones to
find the corresponding channel.
To both protect the transmitter and save power, the transmitter automatically
switches off after approximately one minute if the signal that it receives from the
audio source is too weak for proper reception. If however the signal returns to an
acceptable level, then the transmitter automatically switches back on.
CHARGING THE BATTERIES
1. Place the On/Off switch on the receiver headphones in the Off position.
2. To recharge the headphone batteries, place the headphones on the
transmitter, taking care to ensure that the charge contacts touch the
transmitter's charge prongs.
3. The charge process starts automatically and the green indicator light comes
on. Be sure to charge new batteries for 24 hours before using them for the
first time in the headphones.
WARNING:
Never attempt to recharge conventional dry cells.
Never use another type of battery or non-rechargeable batteries to replace the
rechargeable (LR03/AAA) batteries supplied. When the headphones are not in
use, move the switch to the OFF position to avoid damaging the batteries.
The batteries must always be fully charged before use. An initial 24 hour charge
is required to guarantee an acceptable service life for the rechargeable batteries.
Always ensure that the headphones are switched to the Off position while the
batteries are charging.
IMPORTANT:
This unit can be operated with rechargeable batteries only. When replacing the
batteries or when disposing of the unit, always comply with applicable laws
relating to the disposal of batteries. Please place them in a proper disposal
container to ensure that they are eliminated safely and in an
environmentally-friendly way. Thank you.
REPLACING BATTERIES
Rechargeable batteries have a long service life. If it is however necessary to
replace them, proceed as described below:
Only use rechargeable batteries of the type specified under the “Technical
specifications” heading.
The rechargeable batteries supplied with the headphones must absolutely not
be taken apart, disposed of in an open fire or short circuited.
Carefully remove the cloth padding
around the left and right headphones.
