5. The charger may be opened, serviced, and repaired by authorized personnel only. The charger con-
tains no user-serviceable parts.
6. Place the charger at least 1 inch away from walls or other equipment to ensure adequate heat dissi-
pation 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 AC adapter with an output
voltage of 5 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 pre-
vent unwanted discharging, be sure to remove the transmitter(s) from the charger every time you dis-
connect the charger from power.
10.Do not place the charger near heat sources such as radiators, heating ducts, or amplifiers, etc. and
do not expose it to direct sunlight, excessive dust, moisture, rain, mechanical 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 cleaners or cleaning agents containing
alcohol or solvents since these may damage the enamel and plastic parts.

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) from the charger every time you disconnect the
charger from power.
2. Be sure to dispose of used batteries as required by local waste disposal rules. Never throw batteries
into a fire (risk of explosion) or garbage can.
3. When scrapping the charger, separate the case, circuit boards, and cables, and dispose of all com-

1 CU 400 charger
Check that the packaging contains all of the items listed above. Should anything be missing, please con-
tact your AKG dealer.
The CU 400 has been designed specifically for use with the WMS 400 system.
The charger provides two charging slots specially shaped to accept the HT 400/PT 400 transmitters. The
charging slots operate completely independently so you can charge two rechargeable batteries simulta-
neously. You do not need to remove the battery from the transmitter for charging.
Designed specifically for use with the WMS 400 transmitters, the CU 400 charger
• monitors battery voltages and temperatures during charging;
• generates a flag signaling the end of the charging cycle upon reaching maximum capacity;
• monitors all required safety parameters and will stop the charging cycle if one or more safety para-
meters are out of range.
The charger checks the battery inside the transmitter and will automatically deactivate the charging func-
tion if it detects a dry battery.
There is one STATUS LED in front of each charging slot.
These tricolor (red/orange/green) LEDs indicate the current operating status of the charger.
The DC 5V jack on the rear panel accepts the DC cable on the included AC adapter.
1 AC adapter (if checked on the
packaging)
