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 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 measure-
ments and must replace the batteries.
1. Open the battery compartment at the back of the instrument.
2. Replace the batteries – ensure they are inserted 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.
Which batteries and which procedure?
Use two new, longlife 1.5V AAA batteries. Do not use batteries beyond
their expiration date. If the monitor is not going to be used for a pro-
longed 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
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 batteries!
• Recharge these batteries using an external charger and follow manu-
facturer’s instructions carefully.
