Recovery Cycle - AKG CU 4000 User Instructions

Partially discharging the BP 4000 many times may reduce its capacity (memory effect) or
affect the accuracy of the remaining-capacity display.
The recovery cycle performed by the CU 4000 charger reduces the memory effect and re-
stores the accuracy of the remaining-capacity display.
After approx. every 16 partial-discharge cycles, the device display will indicate "Err.Acc" and
"--.-" instead of the hour display. (The remaining battery capacity will only be indicated by
the bar graph.) Once you insert the device into the charger, the RECOVER LED will start
flashing orange.
These messages request you to start a recovery cycle as soon as possible. The charger will
not perform a recovery cycle before you have pressed the RECOVER key for at least 3 sec-
onds.
• In most cases, the "Err.Acc" or "Rec.Acc" message in the device display is only a re-
quest to perform a recovery cycle rather than an error message!
• However, if the "Err.Acc" message comes up again when you power the device up
after a successful recovery cycle (the RECOVER LED will not flash orange on inserting
the device), there may be a communication problem between the device and the
BP 4000. In this case, please contact your nearest AKG Service Center.
