5.10. Battery Charge Indicator
Batteries almost discharged
When the batteries are approximately 75% used the battery sym-
bol will flash as soon as the instrument is switched on (if at least
one of the batteries still has some charge). Although the instru-
ment will continue to measure reliably, you should obtain re-
placement 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 batteries.
The battery compartment is located on the back side of
the device (see illustration).
a) Remove cover from the bottom plate, as illustrated.
b) Insert the batteries (4 x size AA ). Always use AA long
life batteries or alkaline 1.5v batteries.
c) 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.
d) 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 expira-
tion date. If the monitor is not going to be used for a prolonged period the batter-
ies should be removed.
Using rechargeable batteries
You can also operate this instrument using rechargeable batteries.
• Only use "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 in-
strument for a week or more, always remove the rechargeable batteries!
• Recharge these batteries using an external charger and follow manufacturer’s
instructions carefully.
