• Charging begins automatically; the Charge LED CHARGE
(2) on the transmitter turns green as soon as the charging
contacts of the transmitter and headphones are connected.
The device now switches automatically to standby mode.
• When charging is complete, the green Charge LED (2) goes
out.
8.0 Operation
8.1 Receiving an external audio source
Switching on the transmitter
• Switch on the playback device (TV or audio component)
that your transmitter is connected to, and initially set the
volume to about 30–40% of the maximum volume to avoid
damaging your hearing during setup.
• Press and hold the Power button (11) for one second to
switch on the transmitter. The Power status LED (11) begins
to light up blue. The INPUT status LED (10) begins to flash
blue (Auxiliary Input display).
• The INPUT status LED (10) is constantly lit blue as soon as
an audio signal is received.
• If no audio signal is received, the transmitter automatically
switches to standby mode after about 5 minutes. The Power
status LED (11) is lit red.
• Alternatively, you can later use the Power button (23) on
the remote control. Note here that the transmitter must be in
standby mode. The Power status LED (11) is lit red.
Switching on the headphones/receiver
Warning – Volume
• Using this product limits your perception of ambient
noise. For this reason, do not operate any vehicles or
machines while using this product.
• Always keep the volume at a reasonable
level. Loud volumes, even over short
periods, can cause hearing loss.
• Switch on the headphones by pressing and holding the Pow-
er button (19) for about 2 seconds. The Power status LED
(Fig. 6) lights up red, and then changes to green as soon
as there is a signal connection between the transmitter and
headphones. If no audio signal is detected, the LED stays red.
Note on pairing transmitter and receiver
• Should the LED stay red, you will need to pair the transmit-
ter and receiver. To do so, switch the transmitter completely
off using the Power button (11) and the Power button
(19) of the headphones. No LED is lit on the transmitter or
headphones. Now press the Power button (19) on the
headphones and keep it pressed until the Power status
LED flashes green (about 5 seconds). Press the Power
button (11) on the transmitter within the next 15 seconds.
An acoustic signal will sound to confirm successful pairing.
• After successful pairing, the playback device (for example,
TV) should now be audible through the earpads.
• Adjust the headband and put the headphones on.
• Set the desired volume using the volume control (18) on
the headphones.
Note
To get the best possible playback (and to avoid unwanted
noise of the playback device), initially reduce the volume of
the headphones (18) and set the volume of the playback
device (for example, TV) to about 70–80%. Then adjust the
volume (18) on the headphones to suit your needs. This
is important for analogue input selection in particular (for
example, headphone output of the TV).
• If the charge level of the headphone batteries is low, the
Power status LED (Fig. 6) on the headphones will flash red.
Five minutes before automatic switch-off, a warning tone will
also sound: one tone per minute for four minutes and two
tones in the last minute. The headphones then switch off
automatically.
Note
• In the case of interference or poor reception, the head-
phone sound is muted and the LED is lit red.
• These headphones can also be used as standard wired
headphones. For this purpose, connect the headphone
output socket of your playback device to the 3.5 mm
stereo jack socket on the headphones (20) using an an-
alogue audio cable (package content #31). Please ob-
serve the technical specifications for the audio/headphone
output in the operating instructions of your playback
device; or, if anything is unclear, consult an expert.
• If you place the headphones onto the charging contacts
(1) during operation, the headphones switch off (Power
status LED turns red) and the transmitter goes into standby
mode (Power status LED (11) is lit red). At the same time,
the wireless connection is interrupted and the headphones
go into charging mode (CHARGE LED is lit green).
• As soon as an audio signal is detected again (and the
headphones are removed from the charging contacts), the
transmitter automatically switches back on and the Power
status LED (11) is lit blue; the Power status LED on the
headphones is lit green (Fig. 6).
