Exchanging the buffer battery

CAUTION
There is a risk of explosion if unsuitable batteries are used. Only use
leakproof alkaline manganese batteries.
If you leave the photometer switched on during the exchange or
insert the new batteries within a minute after taking out the old
ones, the date and time are retained in the photometer.

The power consumption of the clock is very low. The lifetime of high quality
batteries is at least 5 years.
Dispose of the batteries at a suitable facility according to local legal require-
ments. It is illegal to dispose of the batteries with household refuse.
Within the European Union, the batteries are removed at a specialized treat-
ment center at the instrument's end of life. The instruments are taken to one
of those specialized treatment centers via the recycling system set up for this
purpose.
