Operation of the PVPM
-12-
●
The device will power off automatically, if the battery voltage becomes too low. Recharge the battery before
you use the device again. Caution: charging is only allowed in the temperature range between 0°C and
40°C. If the battery temperature is outside this range, charging will not proceed.
●
If the battery voltage becomes lower and the device estimates an operation time left of less than 30 minutes,
the LED „State of charge“ will blink red.
●
The battery then should be charged within short time or the device should be powered externally.
