Powering the Transmitter Cradle Off
You may power the transmitter cradle off whenever it is not needed. When powered off, it will not
transmit any RF signals but the headphones battery will still be charged.
1. Slide the On/Off switch (12) on the transmitter cradle to the “OFF” position. The send
indicator (17) on the transmitter goes out.
You may optionally power the transmitter cradle using conventional batteries. For more
information see page 69 – “Powering the Transmitter Cradle Using Batteries”.
Synchronising the Headphones and Transmitter Cradle
After powering the headphones and the transmitter cradle on, both devices should synchronise
automatically. This process may take a while (sometimes more than 1 minute), but normally you
just have to be patient.
Under unfavourable circumstances, however, the audio signal may be subject to interference. This
may happen if you are using a baby phone or a wireless keyboard and mouse set nearby. In this
case you can synchronise the devices manually to locate an interference-free channel.
1. Power the transmitter cradle on by sliding the On/Off switch (12) on the transmitter cradle to
the “ON” position.
2. Power on the connected audio source and start playback. The send indicator (17) on the
transmitter cradle should light up green.
3. Slide the mode selection switch (6) of your headphones to the “WL” position.
4. Power the wireless headphones on by pressing the On/Off button (9) once.
5. Press and hold the synchronisation button (3) of the headphones and the synchronisation
button (13) of the transmitter cradle for at least 1 second.
The RF reception indicator on the headphones (2) and the send indicator on the transmitter
cradle (17) start blinking. As soon as both devices have synchronised, both indicators will
light up green.
6. If necessary, repeat step 5 if you are not satisfied with the reception quality or you still have
interference from other devices.
Synchronising the transmitter cradle and the headphones can take a while. If
there are many wireless devices nearby using the 2.4 GHz RF technology, the
transmitter cradle and headphones first have to find a free communications
frequency. Any frequencies that are already occupied by other devices will
not be used. This is also known as “WLAN Skipping and Hopping”.
