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 slot 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.

• Remove all batteries, and unplug the charger.

• Connect another device to the mains outlet to ensure there is power.

• 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.

• Inspect the charge slot contacts for damage (are they bent, flattened, twisted or bro-

ken).

• Try inserting a battery that you know to be working in the charger slot.
