ies or 3 x 1.5 V type AAA batteries the
correct way round.

10 hours when the device is switched

Note
Preparing the device for first use
• Before the first use, the batteries should
be fully charged. The charging process
lasts for approx. 10 hours. The device
offers an operation period of approx.
16 / 22 hours after this.
• You will get the maximum capacity from
your battery if you charge it at least once
every 6 months. To do this, disconnect
the device from the mains and run the
battery down through normal use. Then
fully charge the battery up again.
• The maximum battery capacity can only
be reached after it has been charged
several times and is dependent on many
factors (battery state, ambient tempera-
ture, means and frequency of charging
etc.).
Note
Observe the battery level indicator in the dis-
play and replace the batteries in good time.
