Sensor Module Replacement
Please take the following steps to install a new
sensor module. (VERY IMPORTANT: The
device MUST BE TURNED OFF in order to
avoid IMMEDIATE DAMAGE to the sensor.) Open the easy-
replace sensor panel.
You will see the
sensor module.
Remove the module by
pulling it straight
back.
Insert a new sensor
module in the
original position.
Make sure the new
sensor module is
firmly secured.
Close the easy-
replace sensor panel.
Ready for testing!
Warnings
a. WAIT AT LEAST 20 MINUTES AFTER EATING OR DRINKING BEFORE TESTING. A
breathaly er examines “lung air” samples, not “mouth air” to calculate alcohol content. Any
“contaminants” in the mouth, including alcohol, food, smoke, or even excess saliva, may
interfere with testing. This includes alcohol-based mouthwash or similar products. This is the
most common cause o improper use and incorrect results.
b. Avoid testing in high wind or enclosed spaces. Poor ventilation may also lengthen the time
required for warm up between tests.
c. Do not blow smoke, saliva or other contaminants into the mouthpiece, as the sensor may
become damaged.
d. Do NOT use the Premium as a tool to drink and drive.
e. Keep out of extreme temperatures and out of the reach of children.
f. To maintain accuracy, the sensor module inside the Premium must be replaced every 200 tests
or at least once yearly (whichever comes first). Large numbers of "high positive" (high
alcohol) readings may require replacing the module much sooner than normally expected.
g. WARNING DISPLAY “Flow”: If you see “Flow” in the display, the breath sample was not
strong or long enough for measurement. As soon as you start blowing into the device, you
will hear a long beep indicating how long you should blow.
h. WARNING DISPLAY “Cal”: If you see “Cal” in the display, the Premium needs a new sensor
module. I the cumulative test counter reaches 300 tests, the Premium will display Cal
automatically. Please purchase and install a new sensor module.
i. WARNING DISPLAY “Bat”: If you see “Bat” in the display, the battery power is low. Please
replace the batteries.
