Battery change indicator
Batteries almost discharged
When the batteries are approximately
75% used, the battery symbol will flash a
few times as soon as the instrument is
switched on (if at least one of the batter-
ies still has some charge). Although the
instrument will continue to measure
reliably, you should obtain replacement
batteries.
Batteries discharged – replacements
required
When the batteries are discharged, the
battery symbol will appear, unblinking, as
soon as the instrument is switched on.
You cannot take any additional measure-
ments and must replace the batteries.
1. Open the battery compartment on the
bottom of the instrument.
2. Replace all the batteries – ensure they
are correctly connected, as shown on
the symbols in the compartment.
3. The memory retains all values although
date and time (and possibly also set
alarm times) must be reset – the year
number will flash automatically after the
batteries are replaced.
4. To set date and time, follow the procedure
described in Section 4.2.
Note: Use four new, Long-Life 1.5 V AA
batteries. Do not use batteries beyond
their expiration date. If the monitor is not
going to be used for a prolonged period, the
batteries should be removed.
Rechargeable batteries are not
recommended.
