5.9. 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
batteries 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 measurements and must replace the
batteries.
1. Open the battery compartment on the bottom of
the instrument.
2. Replace all of the batteries at the same time –
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.
