Battery indicator < How to read the battery indicator > When the battery is completely charged Charging is needed. When the battery needs charging, it is impossible to start recording or editing. When the battery is completely discharged, the whole battery indicator will flash. Recharge the battery or replace the alkaline battery with a new one. When the battery has run completely out, "BATT EMPTY" (main unit) and "Lo BATT" (remote control unit) will appear. Then, the power will be disconnected automatically. Notes: When using the unit with an alkaline battery or a rechargeable battery, the battery indicator will not display correctly the remaining capacity for approximately 20 seconds after the power has been turned on. When the AC adaptor included with this unit or a separately available car adaptor is used, the battery indicator will not be shown. The number of bars shown in the battery indicator may increase or decrease, depending on the operation being performed. This is normal. When the rechargeable battery and the alkaline battery are used at the same time, the rechargeable battery is used first, and then the alkaline battery. Since the battery indicator shows the remaining amount of the particular battery being used, the number of bars will increase when the unit switches to the alkaline battery.
