Q.No.78: The clock-calendar is reset when I replace the batteries.
Ansi COOLPIX 990, 950, 910 (900s), 900 j
The clock-calendar and the memory element in which camera settings are stored are powered by a separate internal battery.
After AA batteries have been inserted in the camera or the optional AC adapter connected, this battery will charge in about ten hours.
Once fully charged, the battery is capable of providing about three days of back-up power when the AA batteries are not inserted or the optional AC adapter not connected.
(In the case of the COOLPIX 900 and 910 [900s], charging begins after the camera has been turned on and then off.)

Charging ends automatically after ten hours, with the result that if the camera is left unused for a long period, the clock-calendar will be reset even when the main batteries are left in the camera.
Charging will begin again when the main batteries are reinserted or the AC adapter unplugged and the reconnected.

After charging the battery by leaving the main batteries in place or the AC adapter connected for ten hours, reinsert the main batteries or unplug and reconnect the AC adapter and charge the battery again.
If the clock-calendar is still reset after this procedure, this may indicate a camera malfunction.
