TIP
: For best results, always use a quality brand of Alkaline battery
and replace as soon as the batteries become low (see section
2.5
).
WARNING
: Do not mix batteries of different technologies, or
use recharged alkaline batteries as these are prone to overcharging
and leaking, which may cause permanent unit damage and
malfunction.
The batteries are fitted by unclipping the battery cover on the back
of the unit, and inserting both batteries with their positive terminals
pointing towards the top of the unit.
