During the connection, the device is completely controlled 
by the computer.
7. Data Memory
This device automatically stores the last 200 measurement values.
Viewing the stored values
Press the M-button 2briefly, when the device is switched off. The 
display first shows «M» AS and then a value, e.g. «M 17». This 
means that there are 17 values in the memory. The device then 
switches to the last stored result.
Pressing the M-button again displays the previous value. Pressing 
the M-button repeatedly enables you to move from one stored 
value to another.
Memory full
Pay attention that the maximum memory capacity of 200 
memories is not exceeded. 
When the 200 memory is full, 
the oldest value is automatically overwritten with the 
201st value.
 Values should be evaluated by a doctor before 
the memory capacity is reached – otherwise data will be lost.
Clearing all values
If you are sure that you want to permanently remove all stored 
values, hold down the M-button (the device must have been 
switched off beforehand) until «CL» appears and then release the 
button. To permanently clear the memory, press the M-button 
while «CL» is flashing. Individual values cannot be cleared.
8. Battery Indicator and Battery change
Low battery
When the batteries are approximately ¾ empty the battery symbol 
AR
 
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 AR 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 AT at the back of the device.
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 3.».
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 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.
9. 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.
1. Plug the adapter cable into the mains adapter socket 8in the 
blood pressure monitor.
2. Plug the adapter plug into the wall socket.
When the mains adapter is connected, no battery current is 
consumed.
10. Error Messages
If an error occurs during the measurement, the measurement is 
interrupted and an error message, e.g. «ERR 3», is displayed.
Error Description Potential cause and remedy
«ERR 1» Signal too 
weak
The pulse signals on the cuff are too 
weak. Re-position the cuffand repeat the 
measurement.*
«ERR 2» Error signal During the measurement, error signals 
were detected by the cuff, caused for 
instance by movement or muscle 
tension. Repeat the measurement, 
keeping your arm still.
