5.9. Battery change 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 as soon as the instrument is switched on.
You cannot take any additional measurements and must
replace the batteries.
1. Open the battery compartment at the back of the instrument
by pushing inward at the two arrows and pulling it out.
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
must be reset - the year number therefore flashes auto-
matically after the batteries are replaced.
4. To set date and time, follow the procedure described in
Section 4.2.
Note:
Use four new, longlife 1.5V 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 for use
with this device.
