Operation
· Press the 'ON' key once to turn on the device. When the machine
is powered on, 'ALCO' will be shown on the LCD display. Press
the 'OK' key. The sensor preheating will be activated. 'PH' will
flash three times and begin to count down (from 'PH99' to 'PH90-
00'). 'READY' & "BLOW" will flash alternately with beep tones
when the machine is ready to take a breath sample.
Note: the device will count down for 30 seconds. Please take a
test within this time.
· When ready to take a test, the user should blow continuously
through the mouthpiece for about 5-7 seconds. Stop blowing
once you hear a 'beep' tone. If the sampling is successful, 'Anly"
will flash upon the display, indicating an analysis of the sample
is underway. A reading will then display upon the screen.
If the blowing time is too short, the airflow from the user is too
soft or is interrupted, 'ERR' will be shown on the LCD. (indicating
an error) The user may press the 'OK' key for a new test. Test
results are displayed on the LCD within 10 seconds.
