Warning:
• Observe the correct polarity when placing the batteries.
• Only use 1.5 V AA batteries or 1.2 V AA rechargeable batteries of the same type and
charge condition.
Under typical operating conditions the delivered Alkaline cells run for approx. 10 hours. In case of
frequent battery usage, we recommend the use of rechargeable batteries for environment protection.
The use of backlight, RS232 or the network cuts the battery runtime short. When using these features, use
batteries with large capacity (>2000 mAh).
Changing batteries
To open the lid of the battery compartment, stick a screwdriver into the mould and press the lid down,
away from the housing.
Observe the correct polarity when placing the new batteries (see sign in battery compartment).
Charging batteries
Remove rechargeable batteries from the instrument for charging them.
