Do not leave fl at batteries in the measuring
device. Even batteries protected against
leaking can corrode and thus release che-
micals which may be detrimental to your health or
which may damage the appliance.
To prevent leakage, remove the batteries if the device is
not used for longer periods of time.
Leaking or damaged batteries may cause alkali burns
if in contact with skin. It is therefore advisable to use
suitable protective gloves.
Make sure that the batteries are not short-circuited. Do
not throw batteries into the fi re.
Batteries should not be recharged. Danger of explosion.
