1. Remove the ear pad from the left-hand earphone.
2. Remove the old batteries.
3. Insert the new batteries into the battery compartment (4). Make sure to align the
batteries with the polarity marks inside the battery compartment.
4. Replace the ear pad on the earphone aligning the four pins on the ear pad with the
matching openings in the earphone base plate.
1. Operating switches on or connecting the transmitter to your audio source may cause
clicks which at high volume settings may affect your hearing. Therefore, be sure to set
the
VOLUME control (6) on the headphones to minimum before switching between
different sources (tuner, turntable, CD player, etc.) or connecting the transmitter.
2. Listening over headphones at high volume levels, particularly over extended periods of
time, may damage your hearing.
3. Your K 105 UHF is a radio frequency device that conforms to the strict European and
FCC standards. For physical reasons that have nothing to do with the quality of the
product, extremely strong interference sources may affect reception. In order to maintain
interference-free listening pleasure, do not operate your K 105 UHF in the close vicinity
of radio equipment, cellular telephones, or directly above TV or computer monitor picture
tubes. The supplied connecting cable is long enough to allow the transmitter to be plac-
ed at a safe distance from interference sources.
Interference caused by other users of the 914 or 864 MHz LPD band are beyond AKG’s
control.
We recommend to clean the transmitter and headphones surfaces using a soft cloth
moistened with water.
