Instruction Manual

(red) range. The classification corresponds to the 4 ranges in the
table as defined by the international guidelines (ESH, ESC, JSH), as
described in «Section 1.».
6. Data Memory
At the end of each measurement, this device automatically stores the
result, including date and time.
Viewing the stored values
Press the M-button 5 briefly, when the device is switched off. The
display first shows «
M » AL 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 60 memo-
ries is not exceeded.
When the 60 memory is full, the oldest
value is automatically overwritten with the 61st 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.
How not to store a reading
As soon as the reading is displayed press and hold the ON/OFF
button 1 until «M» AL is flashing. Confirm to delete the reading by
pressing the M-button 5.
7. Battery Indicator and Battery change
Low battery
When the batteries are approximately ¾ empty the battery symbol AO
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 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.».

The memory retains all values although date and time must be
reset – the year number therefore flashes automatically after
the batteries are replaced.
