6 Device maintenance and cleaning
6.1 Safety during maintenance
NOTICE!
Risk of material damage during maintenance!
A short-circuit or damage to the electronics of
the device is possible during maintenance if the
following instructions are not observed:
– Only allow Customer Service to perform
work on the device’s electronics.
– Before performing any work for maintenance
or cleaning, disconnect the USB cable from
the PC or tablet computer.
– Keep moisture away from live parts.
6.2 Replacing the rechargeable batteries (ChronoMaster Air only)
When the runtime of the rechargeable batteries decreases,
this is due to ageing of the rechargeable batteries that are
installed. The ChronoMaster Air features a design that allows
the operator to replace the rechargeable batteries.
Ensure that the rechargeable batteries are
replaced correctly!
– Do not replace rechargeable batteries with
primary batteries (non-rechargeable bat-
teries).
–
Do not replace individual rechargeable bat-
teries, but rather all 4 rechargeable batteries
at once.
–
Use rechargeable batteries of type “Eneloop”
in size AAA (HR03) – they can be ordered
from the company Witschi AG.
