3.2 Replacement Ear Pads
To mount the supplied, more solid
replacement ear pads, refer to fig. 9:
1. Remove the ear pads (9) from the
speaker capsules.
2. Press the replacement ear pads (10)
onto the speaker capsules as shown
in fig. 9.
4 Placing the Transmitter
Refer to fig. 1.
The T 122 IR transmitter uses infrared
waves to transmit the audio signal to the
receiver in the K 122 IR headphones.
Infrared waves propagate in the same
way as visible light and cannot penetrate
walls or doors. Therefore, place the
transmitter where you can see it from all
over the room.
5 Connecting the Transmitter
Check that the AC mains volt-
age stated on the AC adapter is
identical with the AC mains
voltage in your area. Operating the AC
adapter off a different AC mains volt-
age may damage the unit.
Refer to fig. 2 A: audio source with head-
phone output ("

nector (A ... SCART adapter).
" or "PHONES");
BALANCE K 122 IR
1. Before connecting the transmitter to
your audio source (TV set, radio, hi-fi
system, etc.), switch power to the
audio source off.
2. Connect the transmitter to your audio
source using the supplied AK 2 con-
necting cable (white = left-hand chan-
nel, red = right-hand channel).
3. Plug the cable on the supplied AC
adapter into the DC 12 V jack on the
transmitter rear panel.
4. Plug the AC adapter into a convenient
power outlet.
The six infrared radiators on the trans-
mitter front panel will be lit.
6 Charging Battery Packs
Before you can use the headphones, you
will need to charge the battery pack
inside the headphones. We recommend
charging the supplied replacement bat-
tery pack at the same time.
Refer to fig. 3.
1. Place the headphones (1) on the
transmitter (2).
2. Insert the supplied replacement bat-
tery pack (3) into one of the charging
slots in the transmitter side panels.
The charging process will start auto-
matically. The appropriate indicator
LED(s) (4a or 4b for the replacement
battery packs, 4c for the battery pack
inside the headphones) will be lit red.
The two battery packs will be fully
charged in approx. four hours. The
indicator LEDs (4) will remain lit.
You can leave the headphones on the
transmitter and the battery packs
inside the charging slots without risk-
ing to overcharge the batteries.
