4 Getting started
4.1 Internal battery
The device can be powered either by the internal rechargeable battery (more than 12 hours with
continuous operation) or via the mains adaptor.
During charging, the LED glows red. It will turn green as soon as the battery is fully charged.
When the battery is fully charged, the voltage is approx. 4.25 V. The voltage is shown in window M07.
The battery is nearly flat when the voltage falls below 3 V. The device also indicates the remaining
battery life which is determined internally via the voltage. The indication of the remaining battery life is
just a rough guide value.
