FUEL CELLS
Fuel cells are highly durable sensors that are ca-
pable of providing accurate breath alcohol results
for years. There are however, a few precautions
you should take to make certain that these devices
perform for the longest period of time possible.
Use the device. Fuel cells like moisture. It is a good
idea to take tests periodically to provide needed
moisture to the fuel cell, especially in dry climates.
You do not need alcohol, just breath.
Avoid cigarette smoke. Make certain no one is
permitted to blow cigarette smoke into the unit.
This can damage the fuel cell quickly.
CLEANING
Use of a mild disinfectant cleaner and a soft cloth
on the outside of the case is recommended period-
ically to keep your unit clean. Do not use alcohol to
clean the unit.
BATTERIES

about 160 hours of “on” time which can equate to
as many as 6000 to 8000 tests. It is recommended
you use high-quality alkaline batteries with your
unit.
