Preparation for the Test
1. Push the battery cover (on the back of the device) downwards
and open it (1A). Install the 2 AAA batteries (delivered together
with the device) in the battery compartment while taking note
of the battery polarity (1B). Close the battery cover again.
2. Insert a mouthpiece into the slot on the left front side of the
breathalyzer. Ensure whether it is securely fitted. It is highly
recommended to use a new mouthpiece for every test for
sanitary reasons.
Conducting the Measurement
1. Push the power button on the front of the device, then you
hear one beep tone and shortly will see the number of tests
performed with the device (Note: This number is only shown
as long as you press the power button and if you press and
hold down the power button for more than 5 seconds, the
device will be turned off). If you don`t press it anymore then
you hear another beep tone and see “WAIT” on the display,
additionally a countdown starts.
2. Wait until the end of the countdown you hear 2 beep tones and
then you see “BLOW” blinking on the display. Additionally, you
see 3 horizontal lines on the left side of the display.
3. As soon as you see “BLOW” on the display start blowing steadily
into the mouthpiece for 4 seconds, the device will beep cons-
tantly during the test.
Tip: Blow like you would whistle without a tone (but without a
break).
