7.9.4 Troubleshooting
7.9.4.1 Excessive Charge Duration
The charger is equipped with a recalibration function–a function that fully
discharges and then fully recharges the battery. This process is necessary to
recalibrate the battery capacity gauge internal to the battery. The charger attempts
recalibration when:
• the battery capacity is at less than 30%, and
• the battery has undergone more than 40 partial charge cycles since the last
full discharge.
The recalibration function extends the charge time by up to 2 hours.
7.9.4.2 Indicator Flashing Red
If the indicator flashes red:
• Remove all batteries and disconnect the mains power cable.
• Wait at least 20 seconds, and then plug the cable in again.
If any of the charge well LEDs continue to flash red, the charger is defective and
requires service. If all indicators are flashing red, there is a power supply problem
and the charger requires service.
7.9.4.3 Power LED Does Not Light Up
• Remove all batteries, and unplug the charger.
• Connect another device to the mains outlet to ensure there is power.
• Remove the IEC mains power cable from the charger, and check it for damage.
• Reconnect the mains cable in the charger and mains outlet.
If the power LED still does not light up:
• Unplug the mains cable, and check the fuse at the rear of the charger.
If the fuse appears to be intact, the charger requires service.
7.9.4.4 Indicator Does Not Light When Battery Installed
• Remove the battery, and clean the contacts on the battery and the
charge well.
• Reinstall the battery, and check that it is fully seated in the charger well.
• Inspect the charge well contacts for damage (are they bent, flattened,
twisted or broken).
