6: Care and Maintenance: Batteries
To ensure optimum performance, follow these simple instructions:
6.1 Cleaning the Instrument
Simply wipe over with a LIGHTLY DAMPENED cloth.
Do not use chemical solvents, abrasives or excess water to
clean this instrument: these could damage the case material,
and possibly the various internal sensors
6.2 Changing the Batteries
The standard power supply unit used with the 500 [and unless
otherwise specified at the time of ordering] is two AA cells. These
should give enough power for at least 750 breath tests, depending on
the conditions of use.
When the low power warning screen appears it is recommended that
you change these batteries as soon as possible. When so doing
please remember the following:
Change both batteries together; and
Ensure that each is fitted with its positive end UPwards
