• The normal warm-up countdown is from
6-to-0. However, if it has been more than 1
hour since the last operation, the unit begins
a 14-to-0 warm-up countdown.
• The sensor must be warmed up properly to
report accurate readings. Therefore, always
disregard the results following the initial
14-to-0 warm-up countdown.
• The “SAT” (saturation) message feature
prevents the unit from displaying inaccurate
%BAC readings in the case of sensor
saturation by contaminating agents. For
example, saturation often occurs when
excessive alcohol moisture is deposited on
the sensor from multiple consecutive uses, or
by the accumulation of air contaminants on
the sensor after a long period of inoperability,
such as upon rst use. In such instances, the
unit requires additional warm-up cycles to
properly recondition the sensor.
• If the low battery indicator ashes then
remains on during use, replace the batteries.
• The AlcAlert Breath Alcohol Detector Model
BT5500 includes a backlight. The backlight
turns on and off automatically.
• Always blow into the unit in a consistent
manner. Different blowing conditions may
produce different results.
• Your unit is more accurate when your true
blood alcohol concentration is between 0.02
%BAC and 0.08 %BAC and less accurate
as your blood alcohol concentration is over
0.08 %BAC.

Each individual’s body responds to the
consumption of alcohol differently.
Consequently, a person’s ability to drive safely
may be impaired at a point well below the legal
blood alcohol limit.
The AlcAlert Breath Alcohol Detector should
be used only to give an indication of the
possible presence of alcohol in the blood. You
should not rely upon it as the sole basis to
determine intoxication or whether it is safe to
drive a vehicle, operate equipment, or engage
in dangerous activities.
PNI Corporation does not recommend drinking
and driving. If you are going to drink alcohol,
always have a non-drinking designated driver.
Do not drink and drive!
