5.2 Exchanging the buffer battery
CAUTION
There is a risk of explosion if unsuitable batteries are used. Only use
leakproof alkaline manganese batteries.
Battery service life The power consumption of the clock is very low. The lifetime of high quality
batteries is at least 5 years.
Disposal of
batteries
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.
5.3 Cleaning
Especially after a cell has broken or after a reagent accident, the photometer
should immediately be cleaned (see also section 6.1 A
CTIONS IN THE CASE OF
A BROKEN CELL
).
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.
1 Turn the photometer upside down
and place it on a soft surface.
2 Open the lid of the battery com-
partment (1).
3 Remove the old batteries from the
battery compartment.
4 Insert the four new batteries in the
battery compartment. Make sure
that the poles of the batteries are
in the correct position.
The ± signs on the batteries must
correspond to the ± signs in the
battery compartment.
5 Close the lid of the battery com-
partment.
