DIAGNOSTICS
The charger is equipped with a diagnostic system that automatically checks
the battery pack each time a pack is inserted into the charger.
If no problems are found, the charger will automatically switch to “Fast
Charge” mode as described in NORMAL CHARGING. If a problem is found, it
will be indicated by the charger indicator lights (see Fig. 12), as follows:
• If the green light (A) flashes slowly after battery pack is inserted in charger,
the battery pack temperature is either too high or too low for charging. If left
alone, the charger will continue to monitor the battery pack temperature and
will begin charging when the temperature reaches an acceptable level.
• If the red light (B) flashes continuously, the battery pack has failed (pack is
not chargeable and requires replacement).
