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
(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
flash as soon as the instrument is switched on. You cannot
take any further measurements and must replace the batter-
ies.
1. Open the battery compartment at the back of the instrument by pushing
inward at the two arrows and pulling it out.
2. Replace the batteries – 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 therefore flashes automatically
after the batteries are replaced.
4. To set date and time, follow the procedure described in Section 4.2.
Which batteries and which procedure?
Use four new, longlife 1.5V AA batteries. Do not use batteries beyond their expi-
ration date. If the monitor is not going to be used for a prolonged period the bat-
teries should be removed.
Using rechargeable batteries
You can also operate this instrument using rechargeable batteries.
• Please use only type "NiMH" reusable batteries!
• If the battery symbol ( ) appears, the batteries must be removed and
recharged! They must not remain inside the instrument, as they may become
damaged through total discharge even when switched off. The batteries must
NOT be discharged in the blood pressure monitor! If you do not intend to use
the instrument for a week or more, always remove the rechargeable batter-
ies!
• Recharge these batteries using an external charger and follow manufacturer’s
instructions carefully.
