7.9.4 Troubleshooting

7.9.4.1Excessive 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.

7.9.4.2Indicator 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.

7.9.4.3Power 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.

7.9.4.4Indicator 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).
