Check that the AC voltage stated on the supplied AC adapter is identical to the AC voltage avail-
able where you will use your system. Using the AC adapter with a different AC voltage may cause
damage to the unit.

Your HEARO 888 DIGITAL is a radio frequency device that conforms to the strict European and FCC stan-
dards. For physical reasons that are not related to the quality of the product, extremely strong interfer-
ence sources may affect reception. In order to maintain interference-free listening pleasure, do not oper-
ate your HEARO 888 DIGITAL in the close vicinity of radio equipment, cellular telephones, or directly
above TV or computer monitor picture tubes. The supplied connecting cables are long enough to allow
the transmitter to be placed at a safe distance from interference sources.
Reflections off metal surfaces may reduce the range of your transmitter. Therefore, be sure to place the
transmitter at least 8 inches (20 cm) away from any kind of metal surface.
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 on the head-
phones to minimum before switching between different sources (tuner, turntable, CD player, etc.) or con-
necting the transmitter.
Listening over headphones at high volume levels, particularly over extended periods of time, may dam-
age your hearing.
Interference caused by other users of the same LPD band is beyond AKG's control.
In order to ensure the longest possible service life for the rechargeable batteries, we deliver them
uncharged. Therefore, charge the supplied batteries before first operating your headphones system.
The supplied batteries have been inserted into the headphones for your convenience.
If you operate the headphones on dry batteries, never try to recharge these batteries. This would
cause serious damage to your headphones. Dispose of dead batteries conforming to local waste
disposal rules.
1. Use the OFF/ON switch (1) to switch the headphones off. (As long as the headphones are ON, the bat-
teries will not be charged.)
When the power is off, the Status LED (2) will be dark.
