Changing batteries
If "BAT" appears in the display, a service life of a few hours remains
depending on the operating mode.
Open the battery cover on the front of the instrument.
Take out the empty battery and replace it with a new one. Please only
use batteries of the type: 9V E-block (PP3). Do not use rechargeable
batteries!
Please ensure that the battery is inserted the right way round
(correct polarity) and always use high-quality batteries.
B - 12
Do not throw used batteries into the domestic waste, fire or water,
but dispose of them professionally in accordance with the relevant
legal requirements.
Care
Clean the instrument as necessary with a soft damp cloth that
is lint-free. Ensure that no moisture penetrates into the housing.
Do not use any sprays, solvents, cleaning agents containing
alcohol or abrasives: instead use only clean water to moisten
the cloth.
