5. Data Memory
At the end of each measurement, this instrument automatically
stores the result.
Viewing the stored values
Press the M-button
AO
briefly, when the instrument is switched off.
The display first shows 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
When the memory has stored 30 results, the memory is full.
From this point onwards, a new measured value is stored
by
overwriting the oldest value
.
Clearing all values
All memory data are cleared when batteries are taken out
of the instrument.
6. Battery Indicator and Battery change
Low battery
When the batteries are approximately ¾ empty the battery symbol
AK
will flash as soon as the instrument is switched on (partly filled
battery displayed). Although the instrument will continue to
measure reliably, you should obtain replacement batteries.
Flat battery – replacement
When the batteries are flat, the battery symbol
AK
will flash as soon
as the instrument is switched on (flat battery displayed). You cannot
take any further measurements and must replace the batteries.
1. Open the battery compartment
4
at the back of the instrument.
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 1.5V, size AA batteries.
Do not use batteries beyond their date of expiry.
Remove batteries if the instrument is not going to be used
for a prolonged period.
Using rechargeable batteries
You can also operate this instrument 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
instrument as they may become damaged (total discharge as
a result of low use of the instrument, even when switched off).
Always remove the rechargeable batteries if you do not
intend to use the instrument 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. Error Messages
If an error occurs during the measurement, the measurement is
interrupted and an error message, e.g. «
ERR 3
», is displayed.
* Please consult your doctor, if this or any other problem occurs
repeatedly.
If you think the results are unusual, please read through the
information in «Section 1.» carefully.
Error
Description Potential cause and remedy
«
ERR 1
» Signal too
weak
The pulse signals on the cuff are too weak.
Re-position the cuff and 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.
«
ERR 3
» No pressure
in the cuff
An adequate pressure cannot be generated
in the cuff. A leak may have occurred.
Check that the cuff is correctly connected
and is not too loose. Replace the batteries if
necessary. Repeat the measurement.
«
ERR 5
» Abnormal
result
The measuring signals are inaccurate and
no result can therefore be displayed. Read
through the checklist for performing reliable
measurements and then repeat the
measurement.*
«
HI
»
Pulse or
cuff pres-
sure too
high
The pressure in the cuff is too high (over
300 mmHg) OR the pulse is too high (over
200 beats per minute). Relax for 5 minutes
and repeat the measurement.*
«
LO
»
Pulse too
low
The pulse is too low (less than 40 beats per
minute). Repeat the measurement.*
