Power packs/batteries

EN
Two alkaline batteries have a higher charging voltage when full (at least 3.1 V) than 2 NiMH power packs (at least
2.6 V). The battery indicator in the recorder will therefore also display a higher voltage.
Insert these batteries into the battery compartment in the same way as the power packs (pay attention to polarity).
After the 24-hour measurement cycle, remove the batteries and dispose of them.
Remember that batteries are hazardous waste and must therefore be disposed of separately.
