2.2 Battery Handling
Lithium-Ion rechargeable batteries require routine maintenance and care in their use and
handling. Do not leave batteries unused for extended periods of time, either in the product or
in storage. When a battery has been unused for 3 months, check the charge status and charge
or dispose of the battery as appropriate.
Please especially consider the following points for storing the device:
Charge the battery more than 50% of capacity before storage.
Charge the battery more than 50% of capacity at least once every three months.
Store the battery at temperatures between 5 °C and 20 °C (41 °F and 68 °F).
The battery self-discharges during storage. Higher temperatures (above 20 °C or
68 °F) reduce the battery storage life.
If you start instrument after over-
discharge or you didn’t use it for a long time, the instrument
may take several minutes to start up (even if fans are active). The integrated PC will start
operation not before battery charge level will reach nominal operating conditions.
Position
Function
Right
Start (push switch)
Middle
ON after start or standby
(returns to this position after push)
Left
OFF (MAX. power saving mode, useful for
long term device storage)
If you will not use the instrument for longer time, always switch the Power button
to OFF (bottom position). This enables the maximal power saving mode and will
protect your battery of being over-discharged. Over-discharge of Li-Ion batteries
has huge influence on their lifetime.
