6. 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 (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 at the bottom of the instrument.
2. Replace all of the batteries at the same time – ensure they are
installed correctly, as shown on the symbols in the compartment.
3. The memory retains all values although date and time must be reset –
the year number will flash automatically after batteries are replaced.
4. To set date and time, follow the procedure described in Section 4.2.
Note:
• Use two new, Long-Life 1.5 V AAA batteries.
• Do not use batteries beyond their expiration date.
• If the monitor is not going to be used for a prolonged period, the bat-
teries should be removed.
• We do not recommend using rechargeable batteries.
