Flat battery - replacement
When the batteries are flat, the battery symbol AO 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 3 by pulling off the cap.
2. Replace the batteries – ensure correct polarity as shown by the
symbols in the compartment.
3. To set date and time, follow the procedure described in Section
«2. Using the device for the first time».
The memory retains all values although date and time must be
reset – the year number therefore flashes automatically after
the batteries are replaced.
Which batteries and which procedure?
Use 2 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.
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
Thuasne BP W1 Basic
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.
