5.8. 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 con-
tinue 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 batteries.
1. Open the battery compartment at the back of the instrument by pushing inwards 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 bat-
teries 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 expiration
date. If the monitor is not going to be used for a prolongued period the batteries 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 dam-
aged through total discharge even when switched off. The batteries must NOT be dis-
charged in the blood pressure monitor! If you do not intend to use the instrument for a
week or more, always remove the rechargeable batteries!
• Recharge these batteries in an external charger and follow manufacturer’s instructions
carefully.
