6. Battery Indicator and Battery change
Low battery
When the batteries are approximately ¾ empty the battery symbol AN
will flash as soon as the device is switched on (partly filled battery
displayed). Although the device will continue to measure reliably, you
should obtain replacement batteries.
Flat battery – replacement
When the batteries are flat, the battery symbol AN will flash as soon
as the device is switched on (flat battery displayed). You cannot
take any further measurements and must replace the batteries.
1. Open the battery compartment 5 on the bottom of the device.
2. Replace the batteries – ensure correct polarity as shown by the
symbols in the compartment.
Which batteries and which procedure?
Use 4 new, long-life 1.5 V, size AA alkaline batteries.
Do not use batteries beyond their date of expiry.
Remove batteries if the device is not going to be used for a
prolonged period.
Using rechargeable batteries
You can also operate this device using rechargeable batteries.
Only use «NiMH» type reusable batteries.
Batteries must be removed and recharged when the flat
battery symbol appears. They should not remain inside the
device as they may become damaged (total discharge as a
result of low use of the device, even when switched off).
Always remove the rechargeable batteries if you do not
intend to use the device for a week or more.
Batteries cannot be charged in the blood pressure monitor.
Recharge batteries in an external charger and observe the
information regarding charging, care and durability.
7. Using a Mains Adapter
You can operate this device using the Microlife mains adapter
(DC 6V, 600 mA).
Only use the Microlife mains adapter available as an original
accessory appropriate for your supply voltage.
Ensure that neither the mains adapter nor the cable are
damaged.
