Warnings Display
How to Change Batteries
If the result is higher than 0.050% BAC, the
breathalyser will display “WARN” and sound
an audible alert.
If the result is above 0.400% BAC, “Hot” signal
is displayed along with alarm sound.
If you have tested over 500 times, CAL will
show up on the display screen for 3 seconds
before warming up for a test. Please send the
breathalyser back for calibration.
The battery voltage is too low to perform a
test. The device will turn off automatically
after showing this signal. Please replace with
new 1.5V alkaline batteries.
The breath sample was not strong enough for
a measurement. Please power on the unit
again and make sure the breath is strong and
steady during sampling.
When the ambient temperature is out of the
working temperature range (5°C~ 40°C) the
unit shows “OUT” and then turns off. Keep and
use the unit within the recommended
temperature range.
The breathalyser’s LCD Backlight will turn red when any of these
errors occur.
Apply a small amount of pressure on the battery cover
located on the back of the unit.
Push down and away from the unit to release the cover.
Replace with new alkaline batteries in the proper
positive(+) and negative(-) positions as indicated. Then,
replace the battery cover.
