INTRODUCTION
The PAS V Alcohol Screening System combines: a) high-intensity, 3-Mode LED flashlight
with b) a dynamic sampling system and c) a miniature alcohol sensor. It "sniffs" ambient air,
the breath, open containers, or enclosed spaces for the presence of alcohol, functioning as a
non-intrusive "extension of the operator's nose. "
The PAS V is used to check alcohol presence/absence with or without a subject's direct
participation. When used without the subject's direct participation it's known as passive
sampling, as opposed to active testing where the subject blows directly into a mouthpiece or
the intake port.
The passive alcohol sensor was developed from prototype sensing devices that had been
produced to specifications proposed by the Insurance Institute for Highway Safety.
The PAS V is designed specifically for use by law enforcement, correctional institutions, and
security personnel. It can be operated with one hand, leaving the other completely free. The
instrument is easy to use and has been designed to withstand the physical conditions
experienced in operational situations. It is resistant to adverse weather conditions and
mechanical shocks. Despite its rugged construction and appearance, the PAS V is no heavier
than an equivalent flashlight. It is well-balanced and comfortable to use for several hours at a
time.
The device has been extensively tested by police in the United States under field conditions.
During these trials carried out by traffic patrols at random checkpoints, use of the instrument
led to an increased number of arrests for Driving While Intoxicated, with the added advantage
of reducing the number of false arrests over conventional sobriety tests.
Further information regarding this precision instrument or its use in screening subjects for the
presence of alcohol can be obtained by calling 1-800-660-SNIF
(1-800-660-7643).
HOW THE PAS V WORKS
When you use the PAS V, a small, silent pump draws an air sample through a fuel cell
(electrochemical), which generates a small electrical current in the presence of alcohol vapor.
This current is amplified electronically and used to drive a multicolored bar-graph display.
The number of bars lit in the display indicates the presence of alcohol in the air sample.
A NiMH rechargeable battery (no memory) powers the PAS V. Battery life per charge depends
on the mode of light beam being used. Operating on High Power will provide 65 minutes of
continuous use per charge while operating on Low will provide 190 minutes. An integrated fast
charger is provided so that the unit can be ready for use at all times. The charger can be
plugged into either 12-volt automotive power or 110 vac @ 60 Hz. power source. The AC/DC
Charging System has been introduced to make in-vehicle charging more convenient, while
securing the device in the vehicle.
We want you to get the best possible results from your PAS V. Please take the time to study
this manual and to practice using the instrument before depending on it under real-life
conditions.

INITIAL CHARGING
When you receive your PAS V and check the system, the battery may already be
fully charged. Check the low battery indicator. If it is not flashing, the initializing
has already been performed at the factory. You may proceed to use the PAS.
After receiving your PAS V with the AC/DC Charging System, it is important to
follow these steps for getting an initial full charge into the battery.
[1] Apply Power
Insert the battery button-end first. Plug the AC power adapter into a 110-volt AC
electrical outlet. Connect the adapter to the hole in the base of the charger
cradle. Or, to use the auto adapter, follow the same steps except you will plug
the cigar plug into the vehicle outlet. When connected to power, the YELLOW
LED on the charger cradle should come ON to indicate that power is reaching the
cradle input connector. The GREEN LED will be OFF.
[2] Apply Charge
Snap the flashlight into the charger cradle. Make sure it is seated correctly. Now
the GREEN LED should come ON and remain on throughout the charge cycle. IF
the YELLOW LED begins blinking, there is something wrong with the power
source. See section on Fault Conditions.
[3] Full Charge
A fully charged condition may take up to 3.5 hours. When the battery charge
cycle is complete, the GREEN LED will begin BLINKING/FLASHING. This
indicates a trickle charge level has been achieved. It is recommended by the
manufacturer that the unit now be “Reset”. To reset the charger and gain up to
20-35 minutes MORE charge, simply remove the PAS V off of the charging
cradle for a few seconds and then replace. When the GREEN LED begins to
blink again, an additional 20-35 minutes of charge should be gained.
NOTE: If the GREEN LED starts to flash prior to 3.5 hours (in about 15 minutes),
you may only have a partial charge. This condition will result in a shorter than
expected discharge period and the low battery indication on the display will begin
to flash. In this event, restart (reset) the charging procedure and wait until the
green light begins to flash. A fully charged condition should result.

5
Fault Condition
If the Flashlight Switch is left in the “ON” position when placed into the
charger/cradle, the YELLOW LED on the charger will begin to blink after a short
period. You may not be aware the Flashlight Switch has been left in the “ON”
position because the battery may be drained to a level that cannot power the
flashlight lamp. If this condition is observed, press the Flashlight switch to turn it
off and after a short time (depending on battery condition) the YELLOW LED
should stop blinking and begin charging.
Also, when the Flashlight switch is turned off, the RED Low Battery indicator on
the Sensor display will begin to blink, indicating the Flashlight Switch is in the
correct position for charging. This RED Low Battery light will go off after some
battery charging has occurred.
A fully charged battery will last approximately 190 minutes on Low;
65 minutes on High
IT IS RECOMMENDED THAT THE UNIT BE LEFT IN THE
CHARGER/CRADLE WHEN NOT IN USE.
CAUTION! Do not allow the metal case of the flashlight to come into contact
with metal when charging. Such contact may create an electrical short causing
serious damage to the charging system although a “slo-blo” fuse is integrated
into the system to prevent such damage. If the fuse blows, replacements are
available from the manufacturer. Only a 1.5 amp slo-blo fuse should be used.
CAUTION! Occasionally inspect the battery cover wrapping for tears or
punctures as they may cause serious electrical damage to the product.
NOTE: The timing of the low battery indicator on the flashlight usually lasts
approximately 10 minutes before the battery is totally dead.
AVOID A DEAD BATTERY CONDITION; OTHERWISE THE BATTERY
MAY HAVE TO BE REPLACED.

LED FLASHLIGHT OPERATION
Flashlight Control Switch (LED Bulb)
➢Press and Release the flashlight switch (you will hear a “click”) at the top
of the front of the tube. Bulb turns “ON” in “HIGH” mode.
(CAUTION: Bulb will get VERY HOT in “HIGH” Mode – do not touch)
➢Gently tap the same switch to put the flashlight in “LOW” mode. Battery will
last up to 190 minutes in this mode.
➢Gently tap the switch again to put the flashlight in “STROBE” mode.
➢Press and Release the flashlight switch fully (you will hear a “click”) while in
any mode to turn off the bulb. If bulb is off for more than 3 seconds, the
next time the bulb is turned “ON” – it will default to “HIGH” mode.
Bulb Replacement
You will need to replace the flashlight lamp module when it burns out.
Replacement modules (including easy-to-follow instructions) are available from
PAS Systems International.

SAMPLING
It is important to practice these procedures so that they are second nature
when you use the PAS V under field conditions!
STEP 1: FLASHLIGHT ON
For best performance, turn the flashlight on a minute or so before
you plan to use the PAS V Sensor. This activates the fuel cell
heater and ensures that the unit responds quickly to alcohol.
The orange HTR lamp will cycle on and off as the thermostat
regulates the fuel cell temperature. Turning on the flashlight is most
important at low temperatures (see page 10).
STEP 2: BATTERY CHECK
Check that the low-battery (BAT) lamp is not flashing. If it is,
the batteries should be recharged before using the PAS V Sensor.
STEP 3: ZERO CHECK
If you are unsure whether the fuel cell has recovered from the
previous sample, check a sample of alcohol-free air (air blank) and
verify that no bars light up in the display; observe for about 5 to 10
seconds. If bars do light up, wait a minute, then try again. In severe
cases refer to the section on Overload Recovery on page 13 of the
PAS V Instruction Manual.
STEP 4: INTO POSITION
For optimum results, the inlet port on the right side of the PAS V
should be 5-7 inches from the subject’s mouth, and directly in front
of it. Readings may be lower if it is held too far away or off to one
side.
The officer can approach the vehicle in the normal way, using the
flashlight to illuminate the driver and the drivers' hands. Standing in
the safest possible position just behind the center post, the officer
can have the driver roll down the window and turn toward him. In this
location, the officer is in good position to collect a sample with the
PAS. The intake port is on the right-hand side of the flashlight toward
the face and mouth of the subject, allowing easy visibility of the
display.

8
STEP 5: SUBJECT SAMPLING
Encourage conversation to ensure the subject is exhaling when the
PAS V takes a sample.
Summary: Distance: Less than 10 inches (5-7 inches optimal)
Direction: Point intake port at mouth
Talking: Make sure subject is speaking.
REMEMBER "DDT"
Under certain circumstances, if the subject is willing, you may have the subject
take a deep breath and blow slowly and directly toward the sensor’s intake port
while sampling. This will confirm the presence (or absence) of alcohol. Do NOT
hold closer than 4 inches, and do NOT allow the subject to blow in hard bursts.
STEP 6: START SAMPLING
To take a sample, press the PAS Sensor control button and release
it immediately. The GREEN sensor indicator will come on to show
that the sensor is on. The yellow PMP indicator will also turn on for
the 5 seconds that the pump is running and taking the sample. While
the pump is running it is important to keep the subject talking for the 5
seconds. Therefore ask questions that require lengthier answers than
yes or no.
Once the pump has stopped running, it is no longer necessary
to hold the flashlight in position.
STEP 7: PEAK READING
The air pump draws air through the fuel cell for about 5 seconds. If
there is alcohol present the bars in the main display will start lighting
up, with a peak reading in about 2-10 seconds.
STEP 8: PAS V OFF
After noting the peak reading, press the sensor control button again
and release it immediately. The Sensor and main display will turn
off, and the fuel cell will recover. The microcontroller will
automatically turn off the sensor after about 45 seconds and reset for
the next sample.

9
STEP 9: FLASHLIGHT OFF
Turn the flashlight off whenever you are ready to do so.
After detecting alcohol, the fuel cell may need a minute or so to
recover. The recovery time increases with high concentrations of
alcohol and with low operating temperatures (see page 10).
No recovery is needed if no alcohol was detected.
STEP 10: RECORD RESULTS
You may want to record your results into a suitable log or by use
of your body camera. Record the number of bars on the graph that
light up. If no bars on the graph light up, record "Negative for
Detectable Levels of Breath Alcohol”.
Remember: Five (5) Easy Steps for Successful Testing
1. Distance: Position 5-7 inches
2. Direction: Aim Intake Port at mouth
3. Talking: Subject speaks
4. Tap: Sample Pump Light on Light off
5. Read: 5 - 20 seconds
Interpreting the Display
The PAS V is intended for use as a screening device to detect alcohol in or
around a person without the person’s direct or active participation. Because of
the passive nature of the device, it is not possible to obtain precise readings
of breath alcohol levels (deep lung BrAC). The subject might be exhaling out of
the corner of his mouth, or his breath might be deflected by drafts or other
variables in the environment.
Accurate measurements can only be obtained with an evidential quality
instrument, where the subject blows into a mouthpiece. The purpose of the
PAS V is to alert you that alcohol is present and may help you to quickly decide
whether to utilize other field sobriety tests or to use an evidential breath tester in
individual cases.

10
If the PAS V is used in still air at the optimum distance of 5-7 inches from the
subject's mouth, the chart below will give you an approximate indication of the
subject's breath alcohol concentration (BrAC). Roughly, the readings can be
interpreted as follows:
Approximate
BrAC (%)
NOTE: In some situations it is not practical to get the PAS V as close as 5-7
inches from the subject's mouth. The PAS can be used at greater distances, but
readings will be lower. As a rule of thumb, one less bar will light up for every 2
inches beyond the optimum 5-7 inches. Using the PAS V at distances greater
than 10 inches is not recommended for breath-alcohol sampling, because of the
effect of drafts.
Low Temperature Operation
At low temperatures, fuel cells take longer to reach their peak readings of alcohol
level. They also take longer to recover from each positive sample before you can
take another. To overcome this problem, your PAS V includes a thermostatically
controlled heater that maintains a fuel cell temperature of 104◦F (40◦C).
Since the PAS V is normally used at night, the heater comes on automatically
whenever you turn on the flashlight. The fuel cell reaches its operating
temperature within a few minutes, although the exact time obviously depends on
how cold it was to start with. The orange

The sensitivity of the fuel cell is not affected much by temperature. A cold unit
will work just fine, it's simply slower to respond and recover. You don't have to
wait for the fuel cell to warm up.
OTHER APPLICATIONS
Alcohol in Enclosed Spaces
The PAS V is sensitive enough to detect background levels of alcohol in
enclosed spaces such as vehicles and rooms. This is useful for detecting
drinking by minors in cars or at social gatherings, without sampling each
individual's breath.
To detect alcohol in an enclosed space, run the PAS sensor to sample air drawn
from anywhere in the space. Just make sure you don't sample fresh air from an
open door or window.
Crash Victims
If a crash victim is unconscious, it can be important to know whether he or she
has been drinking. This will often determine the best course of treatment. Even if
the victim is conscious, it is important to know whether alcohol might have
contributed to the accident. This will influence the course of any investigation.
Any crash victim who is breathing can be checked with the PAS. An
unconscious subject might be exhaling from the nose instead of the mouth, but
the procedure is the same. You only need a few seconds to take the breath
sample, and you can move away while the PAS V display is reaching its peak
level.
Open Beverage Containers/ Spiked
With open container law, the PAS V is invaluable in determining whether a
beverage container has alcohol in it. This is easily done by sampling the air
above the container.
W
Wa ar rn ni in ng g! !
The air over an alcoholic drink, even a beer, has much more alcohol in
it than a drinker's breath. It is therefore easy to overload the PAS V when
checking beverage containers. Overloading should be avoided whenever
possible, because it takes the fuel cell longer to recover, and its performance will
gradually deteriorate.
To check a container for alcohol, angle the intake port away from the container
opening to dilute the sample. If your first reading is inconclusive, you can always
take another one with less dilution.

12
The PAS V readings should not be taken as an accurate indication of the
strength of the drink. However, with a little experience you should be able to
distinguish between beer, wine, and spirits. Take the time to practice on various
drinks and develop an operating style that avoids overloading the instrument.
CAUTION! Be aware that certain citrus-based beverages, flavored waters, and
some Starbucks coffees have been reported to give a positive reaction when
sampled with a Passive Alcohol Sensor.
For Example: Citrus-Based beverages such as Mountain Dew, Mello Yello,
Code Red, etc., may give positive readings. It’s not clear if these beverages are
in fact fermenting and producing low levels of alcohol, or if certain ingredients are
reacting chemically with the fuel cell in some way to provide a positive reading.
To minimize confusion, always retest subjects (individuals) about 15
minutes after an initial positive reading to verify true alcohol presence and
not the result of residual mouth alcohol from these types of beverages.
However, individuals may “spike” these drinks to cover up their actual
alcohol consumption. Wait 15 minutes and retest the subject (following
sampling instructions on page 7) to verify if they are abusing alcohol.
Further, always conduct an “air blank” between samplings to ensure the fuel cell
sensor is clear of any residual alcohol carried over from the prior sample. “Air
Blanks” are done by simply activating the pump and processing a sample of
alcohol-free ambient air. Observe the display for approximately five to ten
seconds after the sample pump has stopped. If no bars light up you may
assume the sensor is free of any carry-over and you may proceed with sampling
the next subject (individual).
Secondary Investigative Light (On back of device)
To use the Secondary Investigative Light, turn on the PAS V main Flashlight
switch. This will also turn on the Seconday Investigative light on the back of the
flashlight body.
Option1: Green Horizontal Gaze Nystagmus Test (HGN) Light
The HGN test is one of three field sobriety tests developed by the National
Highway Traffic Safety Administration (NHTSA). For more information on
administering the HGN Test can be found at nhtsa.dot.gov
Option 2: Blue Ultraviolet (UV) Light
Hold the UV light several inches above any item or surface to illuminate any UV-
sensitive object or residue.
*CAUTION –Do NOT shine the Ultraviolet (UV) light directly into eyes.

13
CLEARING OVERLOADS
If your PAS is overloaded, it will take a few minutes to recover.
1. Turn on the flashlight to activate the fuel cell heater. This speeds recovery.
2. Turn off the PAS Sensor. This also speeds recovery.
3. After 5 minutes, check the unit with an alcohol-free air sample. If within
approximately 20 seconds, bars still light up in the display, repeat steps 2 and
3 as necessary until the overload has been completely cleared.
4. Your unit is now ready for use.
COMMON QUESTIONS
Q. What if the PAS V detects alcohol, but seems to be giving low
readings?
A. This problem is usually caused by using the PAS V too far from the
subject's mouth, or with the inlet port off to one side (inaccurate
positioning). It can also be caused by a blocked inlet or outlet port,
perhaps by your own fingers. Your unit might need recalibrating.
Q. Why does the display light up several bars with no alcohol present?
A. This can be due to background levels of alcohol vapor in the air, but it is
more likely that the fuel cell has not recovered from the previous positive
reading. If the problem persists when you check a sample of fresh air,
follow the procedure for clearing overloads (see above). Also, frequently
switching the sensor on without a brief waiting period of a few seconds
between switching may result in bars lighting up.
Q. Why does my PAS V appear to be too sensitive?
A. You might be using the instrument to close to the subject's mouth, or it
might need to be recalibrated. Certain mouth washes or freshly applied
perfume or cologne may give high readings temporarily. Alcohol from
these sources dissipates rapidly. Also, always allow the sensor fuel cell to
rest a few seconds between sampling to clear itself of any residual
electrical activity.

14
Q. Why won’t the flashlight come on?
A. If the blue LGT indicator comes on, but the flashlight does not, you have a
burned out lamp module. Otherwise, you might have flat batteries.
Q. Why is the red LED lamp flashing?
A. The batteries are discharged and could give a false reading. Charge them
before using the unit.
Q. Why is my battery discharging so quickly?
A. Be sure to follow the Reset procedure when recharging the battery. To
reset the charge, and gain up to 20-35 minutes more charge, simply
remove the PAS V off of the charging cradle for a few seconds and then
replace. When the GREEN LED begins to blink, an additional 20-35
minutes of charge should be gained.
Q. What if the orange HTR indicator is ALWAYS on when the flashlight is
on?
A. If the HTR indicator fails to cycle on and off as the thermostat regulates the
fuel cell temperature, you may have a defective thermostat. Please return
your PAS V for service.
Q. What if I dropped my PAS V on the ground?
A. The instrument is probably just fine. If it doesn't work, the batteries might
have been crushed by their own weight. Check for this before assuming
that the PAS V needs repair.
Q. What if there seems to be something wrong with my unit?
A. Call PAS Systems International for assistance. Do not attempt to repair the
PAS V yourself. There are no user serviceable parts inside, and you will
void the warranty. Please refer to Service section on page 17.

15
DOS AND DON’TS
In cold weather, turn on the flashlight (and fuel cell heater) before using the PAS
V Sensor. This reduces the response time.
Hold the unit with the inlet port 5-7 inches from the subject's mouth.
Keep the subject speaking when sampling.
Keep your fingers away from the inlet and outlet ports.
Turn off the PAS when not in use.
Treat your PAS V with the respect deserved by any precision instrument. Protect
it from temperature extremes (don't leave it on your dash in the midday sun).
Remove the battery pack if the unit is not going to be used for more than a
month.
Use only the rechargeable battery pack obtained from PAS Systems
International. These are industrial grade batteries with much higher capacity and
longer life than the consumer grade equivalents.
Have the calibration of your unit checked once a year, or whenever it seems to
be losing sensitivity.
Take strong samples from right over an alcoholic beverage. The fuel cell takes a
long time to recover, and frequent overloads will damage it.
Sample raw cigarette smoke. This rapidly damages the fuel cell.
Allow liquids to enter the inlet or outlet ports.
Allow the metal case of the flashlight to come into contact with metal parts of the
vehicle when charging.
Use the PAS V where it is exposed to high winds that can blow the breath
sample away from the inlet port. At the side of a busy road, subjects should be
checked in their vehicles whenever possible.
Subject the PAS V to abuse such as excessive shocks.
Attempt to dismantle the unit. This will void the warranty.
Clean the unit or case with chemical solvents. You might damage the fuel cell
permanently.
