5.10. Battery charge indicator
Batteries almost discharged
When the batteries are approximately 75% used, the battery symbol
will flash as soon as the instrument is switched on. 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 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 possi-
bly 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.
