1. Do not spill any liquids on the charger. This may cause short circuits and contaminate
the charging contacts.
2. If any liquid penetrates into the charging receptacle, disconnect the charger from power
immediately and have the charger checked by AKG service personnel.
3. Never use the charger to charge dry batteries. The charger will detect dry batteries and
automatically deactivate the charging function.
4. Use the charger in dry rooms only.
5. The charger may be opened, serviced, and repaired by authorized personnel only. The
charger contains no user-serviceable parts.
6. Place the charger at least 1 inch away from walls or other equipment to ensure adequate
heat dissipation from the charger. If the charger overheats, the charging cycle will be
stopped immediately.
7. Before connecting the charger to power, check that the AC mains voltage stated on the
included power supply is identical to the AC mains voltage available where you will use
the charger.
8. Do not operate the charger with any power supply other than the included local power
supply or the optional PSU 4000 central power supply from AKG with an output voltage
of 12 VDC. Using a power supply with an AC output and/or a different output voltage may
cause serious damage to the charger.
9. If you will not use the charger for a long period of time, disconnect the charger from
power. To prevent unwanted discharging, be sure to remove the transmitter(s)/receiver(s)
and/or BP 4000 Battery Pack(s) from the charger every time you disconnect the charger
from power.

fiers, etc. and do not expose it to direct sunlight, excessive dust, moisture, rain, me-
chanical vibrations, or shock.
11. Clean the charger with a moistened (not wet) cloth only. Be sure to disconnect the
charger from power before cleaning the charger! Never use caustic or scouring clean-
ers or cleaning agents containing alcohol or solvents since these may damage the
enamel and plastic parts.
12. Use the charger for the applications described in this manual only. AKG cannot accept
any liability for damages resulting from improper handling or misuse.
1. The charger will draw a low current even when the charging mode is off. To save energy,
disconnect the charger from power if you will not use the charger for a long period of
time. To prevent unwanted discharging, be sure to remove the transmitter(s)/receiver(s)
and/or BP 4000 Battery Pack(s) from the charger every time you disconnect the charger
from power.

of all components in accordance with local waste disposal rules.

use a collection/recycling system provided for that purpose and observe local legislation
relating to waste disposal and recycling.
