20 Using the Battery Pack
Changing the battery pack
Switch the ARGUS off and disconnect the plug-in power supply. Afterwards, loosen the
thumbscrew to release the battery pack.
Battery pack handling
The ARGUS may only be operated with the included battery pack. Connecting any
other voltage supply to the battery pack contacts will damage the ARGUS.
Automatic recharging of the battery pack when the ARGUS is switched off
The ARGUS automatically recharges the battery pack (often shortened to "accu" for
accumulator), if the ARGUS is connected to the plug-in power supply and is switched off
and the battery pack voltage is too low. While charging, the ARGUS displays the message
“Charge accu”. If you press and hold the power switch, the ARGUS will switch off before
the accumulators are recharged. The ARGUS remains on after fully recharging the battery
pack.

The supplied battery pack may only be charged in the ARGUS.

Recharge the battery pack fully at least once a month (even if the ARGUS is not used
for a longer period of time).

If the lithium-ion battery pack is stored, it should first be charged to between 40 and
60 % of its capacity. If the lithium-ion battery pack is stored for a longer period of time,
