Appendix 2: Error Codes
You may see the following error codes displayed on the LCD screen
during charger operation.
Err1
: Battery Fault. This generally indicates a reverse polarity. This
issue may be resolved by flipping the polarity switch. This is
accompanied by continuous beeps.
Err2
: Insufficient Input voltage. Make sure that the input voltage is
high enough to charge your battery pack if you are using DC power
sources other than the supplied AC adapter. Refer to the table
below for minimal input voltage levels:

Err3
:
High Temperature.
At the end of the charge, you might also
see the
Err3
symbol. This symbol indicates that the charger has
properly terminated the charge because the battery pack has
reached a preset temperature. This is the equivalence of a full
charge. This does not indicate an overcharge and usually does not
indicate a problem with the battery pack.
Note: If you are charging 1
to 2 battery cells, the probability for Err3 to occur is higher.
Err5:
Battery pack detected during power on. This does not
indicate a problem, but merely informs the user that a battery pack
is connected when the charger powered up. It is recommended to
disconnect any battery pack prior to powering the charger.
