Removable Batteries

The device comes with two removable battery packs. It can operate from either or both of these batteries as well as directly from the AC adapter.

The remaining battery life can be checked both on the device, using the power manager, as well as with the power meter located on the battery itself. The power meter is activated by pressing the Power Test button. The number of LED lights indicates the power level of the battery pack.

Battery Charging

When the device is connected to an AC adapter, any inserted batteries will automatically begin to recharge. While the batteries are charging, the Battery Charge icon on the Indicator panel will be active after 6–12 seconds. When the batteries are fully charged, the Battery Chargeicon will turn off.

Note: When not in use for a month or more, fully charge the battery prior to storing.

When RSWA is turned off, a fully discharged battery will take about 3 hours to recharge. If RSWA is turned on and is not in suspend mode, it will take about 4–5 hours to recharge the battery.

When to Replace the Battery

Over time, the batteries' capacity gradually decreases. It is recommended that the batteries be replaced when they begin to store significantly less charge. Only use replacement batteries approved by Tessonics. The use of unapproved batteries may cause damage to the device and void the warranty.

Warning: Danger of explosion if battery is incorrectly replaced. Dispose of used batteries according to the manufacturer’s instructions.
