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 sani-
tary 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 stea-
dily into the mouthpiece for 4 seconds, the device will beep
constantly during the test.
Tip: Blow like you would whistle without a tone (but without a
break).
