4.9. 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. 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 3.2.
Note:
Use four new AAA 1.5 V 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.
We do not recommend using rechargeable
batteries.
