8. Error Messages
If an error occurs during the measurement, the measurement is
interrupted and an error message, e.g. «Err 3», is displayed.
Use 4 new, long-life 1.5 V, size AAA 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.
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.
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.
