Battery life and battery replacement
The unit can operate with alkaline batteries or with nickel-metal-hydride (NiMH) rechargeable batte-
ries. Depending on the capacity and condition of the batteries, the unit can operate upto 8 days on a
set of batteries based on usage of 30 minutes a day.
• When the battery low indicator (orange) flashes, the batteries should
be replaced. Replace both batteries with new ones.
• The (optional) AC adapter does not function as a battery charger;
rechargeable batteries must be charged in an external battery charger.
• Remove batteries if the unit is not in use for long periods. Failure to do
so could result in damage due to battery leakage.
• Batteries should be treated as chemical waste; disposal should be
done at your retail store or at appropiate collection locations.
