Charging time

An empty battery is fully charged after about 2 hours. Charging is only possible within a temperature range of +5 °C to +40 °C. If the temperature rises/falls 5 °C above/below this, the charge symbol flashes a warn- ing. The mains voltage specified on the power supply unit must not be exceeded (Operating time, p. 98).

Charge icon not visible

If the battery has been discharged fully the charge icon is not immediately visible when the power supply unit is plugged in. It will appear after up to two hours. In this case the battery is fully charged after 3-4 hours.

Only use the power supply unit provided! Display while in service

Charge level display during operation (empty-full):

a d g

A beep sounds when the battery is nearly empty. The charge level of the battery is only displayed correctly after an uninterrupted charging/dis- charging cycle. You should therefore

not remove the battery unnecessarily and where possible not terminate the charging process early.

Additional information

The power supply unit heats up when used for long periods. This is normal and not dangerous.

If the battery is removed for longer than 30 seconds, the clock must be reset.
