1.0System Description
1.1System Overview
Checkpoint's C/PT IX deactivation system dramatically cuts inventory shrinkage
losses from customer shoplifting and employee pilferage when used in conjunction
with a Checkpoint electronic article merchandising system. Although not foolproof,
C/PT IX can reduce losses in retail stores so effectively that the savings will quickly
exceed the system's cost. This manual describes how to install, tune, and test the
C/PT IX system.
A complete C/PT IX system consists of one chassis, one or two pads or scanner
antennas and targets attached to protected inventory. The pad rests on the top of the
checkout counter where tagged merchandise can pass over it. The chassis is usually
mounted under or inside the checkout counter. Clerks deactivate these targets at
checkout. If someone should try to exit through the sensing system with an active
target, an alarm sounds. The manager can then intercept and verify the item has been
properly purchased.
March 9, 2000
FCC ID: D04CP1900
1.1.1How the System Works
One chassis can drive up to two pads or up to two scanner/deactivators or a
combination of both. A random pulsed-RF signal is generated by the chassis.
This signal is sent through a cable or cables connected to one or two pads
creating a RF field above the pad(s). When a Checkpoint target enters the
field, it responds to the chassis' signal by resonating and emitting a signal of its
own. Depends on its operating modes, the chassis either picks up the target's
signal, and amplifies the subsequent pulses to destroy or deactivate the target,
or operates in the high power mode to destroy or deactivate the target all the
time.
1.1.2System Effectiveness
It is possible to subvert the C/PT IX system. For example, targeted
merchandise can be deactivated by customers, then concealed. Customers
could also remove targets from protected merchandise. Customers can learn
these and other tricks to evade security measures.
Most theft loss arises from impulsive shoplifters, who sense an opportunity to
steal and spontaneously act to take advantage of it. C/PT IX, in conjunction
with a sensing system, acts effectively to discourage these casual shoplifters,

•
a recessed power switch,
•
an access hole to the internal volume control,
•
a green LED (

The standard C/PT IX chassis operates on 90 - 264 VAC 50/60Hz /15 VDC supply
with a current rating of over 1.0 A. The C/PT IX uses a resettable fuse. To reset this
fuse, turn off power, wait 1 minute and turn on power.
1.4Remote Unit
When the C/PT IX is configured in IV or VI mode, a remote unit is needed.
On the remote unit’s face are:
•
a recessed power switch,
•
a green LED that lights when power is on,
•
a sonalert that beeps when a live tag is detected by the C/PT IX.

1.5Antenna
The C/PT IX chassis can be used with a variety of antenna configurations.
Checkpoint or some scanner manufacturers produce these antennas.
1.6Target
The C/PT IX system is compatible with all 8.2 MHz deactivatable tags. In addition,
the C/PT IX will alarm when a non-deactivatable tag is placed in its field, but it will
not deactivate the tag. Occasionally, non-deactivatable paper tags ( those with lower
than average breakdown voltage ) will be deactivated, especially when placed near a
corner of the pad where field strength is greatest. The CSE should be aware of this
rare event.

3.2.1Pad Connection
March 9, 2000
FCC ID: D04CP1900
C/PT IX can drive one or two pads or scanner/deactivators. The cable length
for the pad is 8 feet.
(Don’t alter the cable length under any circumstance)
Place each pad in position on its counter. The maximum distance between the
two pads that are connected to a single chassis is 12 feet. The best performance
can be achieved if the pad cable run straight out of the pad for at least 6”
(15 cm) before it changes direction. See Figure 3.2.1. If the direct pad-chassis
route takes the cable back under the pad, beneath the counter top, it’s best to
route the cable along the center of the pad. See Figure 3.2.1. Ensure that
deactivation remains as transparent to the checkout process as possible. Connect
the pads cables to either

3.3Slaving Connection
Whether or not the C/PT IX should be slaved to other EAS systems or deactivation
systems depends on the environment of the site, the layout of the system, and the
settings of the system. Refer to Table 8.1 as a guideline for the minimum distances
required between the various EAS systems and the C/PT IX. If you are not sure,
temporarily plug in and turn on the C/PT IX, attach the oscilloscope probe to the
appropriate test point of the EAS systems receivers as you test for poor detection and
phantoms.
NOTE:The C/PT IX doesn’t have MASTER SLAVE OUTPUT.
It cannot be slaved to each other unless a master source such as
an EAS system or fiber master exists.

C/PT IX Tune Up and Test Procedure
If you haven’t already done so, follow the standard procedure to tune the sensing system to
Checkpoint’s specifications
6.1Center Frequency and Deviation Verify
Since the C/PT IX uses pulse-listen technology, it’s difficult to measure the center
frequency and the deviation using regular tools. Also, since the C/PT IX uses DDS
(Direct Digital Synthesis), the frequency band can not be adjusted. Use dip meter and
the ear phone to verify the center frequency and the deviation. You should
hear the clicking sound with your earphone from 7.6 –8.7 MHz when you sweep the
frequency using the dip meter. See Figure 8.1.
6.2
IV Mode
Follow step 5.2 to configure the chassis
March 9, 2000
FCC ID: D04CP1900
BEFORE
tuning the deactivators.
Detection Field Adjustment
When in IV mode, the detection field should be adjusted properly to achieve
the best performance.
6.3V Mode
Follow step 5.3 to configure the chassis. Test the deactivation height using live 410
tags. The deactivation height should be comparable to the numbers listed in Table
8.2. If the deactivation height is worse than expected, go to Appendix A for the
detailed tuning.
To insure that tags will be detected before they are deactivated adjust R11 to
its minimum setting which is approximately 0.7 VDC. See Figure 8.1.
Sensitivity adjustment
When in IV mode, the sensitivity of the receiver should be adjusted properly
to achieve the best performance.
Adjust GAIN (R4) all the way clockwise (maximum) to achieve better
detection. If phantoms occur, adjust GAIN (R4) counterclockwise slightly
until the phantoms stop.
Test the detection height using standard 410 test tag. The detection height
should be comparable to the numbers listed in Table 8.2. If the detection
height is less than expected, go to Appendix A for the detailed tuning.

listed in Table 8.2. If the deactivation height is worse than expected, go to Appendix
A for the detailed tuning. Test the detection height using standard 410 test tag, it
should be at least 6” or higher if a pad is used.
6.5Interlock Turn-On Time Adjustment
When the interlock function is used, adjust INT TIME (R98) clockwise to increase
the interlock Turn-On time from 0.2 - 10 seconds in LO mode (SW3-3 OFF) and 1min
– 10 min in HI mode (SW3-3 ON). See Figure 8.1.
7.0
After The Installation
Wait until after installation and tuning to show the customer personnel how the deactivator
operates. Ensure that site management is present and let them designate which site
employees will attend. If you have just installed a sensing system and deactivators, explain
the sensing system operation first, then follow with the deactivator operations, as follows:
March 9, 2000
FCC ID: D04CP1900
7.1Turning the Deactivator On and Off
The deactivator should be turned off when not in use to prevent unauthorized
personnel from deactivating tags.
Show the operation of the power switch, and point out the green light on the chassis,
which shows that the power is on. If the sensing system control module is Model N or
later, mention that a key is required to activate the system. If the sensing system is
the master in a slaved configuration, indicate that it must be on before the
deactivators will function.
7.2
How the Deactivator Works
Show how the deactivator operation is similar to the sensing system in that both
systems transmit radio signals which cause tags to respond with their own radio
signals when they come into range. Explain that each system's receiver recognizes the
tag signal then verifies it. Then explain that the difference between the two is what
each does with the verified tag signal. The sensing system alarms loudly upon tag
verification. The deactivator alarms softly at the chassis and disables the tag. When
deactivation is immediate, there will be no audible alarm.
7.3When the Tag Doesn't Deactivate
Explain that tags vary in length of time required to deactivate. Some tags deactivate
instantly, while others take longer. It may be that a very few wouldn't deactivate
automatically. If this should occur, just place a Thank You label over the tag.
Mention that any hard tags, hang tags, or non-deactivatable stickers also will not
deactivate automatically. Clerks must either remove these tags, or mask them with a

COUNTERPOINT IX
Thank You label. For these tags, the deactivator acts as a point of sale detector. It
continues to alarm softly until the tag is removed or masked.
7.4When the Sensing System Alarms
Employees should follow their management's standard procedure for handling sensing
system alarms, just as if there were no deactivators in the store. If there is no
standard procedure, make a mental note to encourage management to set one. Wait
until after you conclude the training meeting to avoid embarrassing management in
front of the employees.
7.5Testing the Deactivator
Employees should turn on the deactivator before use and turn off the deactivator
when unattended. An employee verifies power by viewing the green light on the
chassis. Beyond checking the power on switch, there isn't much need to test the
deactivator's function because it will be immediately apparent should a unit fail to
disable tags.
Show employees how to test for deactivation in case site management should want to
test a unit. In IV and VI modes, use a hard tag, hang tag or non-deactivatable sticker.
Hold it about 18" (46 cm) above each deactivator pad and bring it down slowly to the
pad's surface. Point out alarm occurs at about 10.5" (27 cm) height. Take a
deactivatable sticker and move it down in the same manner. Observe the signal stops
as the tag gets closer. Try to alarm the deactivator again with the same tag to verify
that it has been disabled. Make sure that this activity doesn't alarm any other
deactivator or sensing system. In V mode, use DV1000 and live 410 tags to test the
system.

7.6Operational Problems
Give site management the telephone numbers used for calling Checkpoint service
about equipment problems. Detail how to avoid potential problems by keeping
permanent tags and stickers and also metal objects away from the deactivator pads.
7.7Tagging
Show how deactivatable stickers can now be hidden in protected merchandise.
Remind the customer that metal and foil objects usually can't be protected by pressure
sensitive tags. Detail that all procedures for tagging merchandise covered in the
User's Guide apply also to deactivatable tags. Detail the necessity of maintaining a
tagging system, use of merchandise value or theft activity to decide which
merchandise to tag, and the need for following an established procedure when the
sensing system alarms.

COUNTERPOINT IX
Appendix AFine Tuning
DIP switch settings in Table 5.1 and Performance Matrix in Table 8.4 are based on the tests
performed in the lab under following conditions:
1.Use of 6 feet, #18 cables for the scanners
2.Use of 8 feet, #18 cables for the pads
3Free of any interfering RF systems in an open environment
4.Use of standard 410 test tag in V mode testing
5.Use of standard 410 tags in IV mode testing
In actual installation, these settings may be changed for proper performance of the C/PT IX due to
environmental variations. If you are not able to tune the C/PT IX following the normal tuning
procedure detailed in previous chapters, refer to this chapter for fine tunings.
A.1Detailed Tuning in IV Mode
To fine tune the C/PT IX in IV mode, change switches SW1 and SW2 so that the average
amplitude of the AC signal at ANT (TP2) is both maximized and as flat as possible. Start
with SW1 and SW2 all off and turn on the DIP switches two at a time beginning at position
(1). The following is an example of tuning 12 x 12 pad.

If the C/PT IX phantoms, check the sensitivity as follows:
Scope Settings:
Ch1:Voltage:100mv/divTriggered on Ch1
Time:200us/div
Test point: LISTEN (TP4)
Maximized Intensity
Ensure the peak amplitude of the AC signal without the tag at LISTEN (TP4) is below 0.5Vp-p as
shown in A1.4.

A1.4 AC Signal at LISTEN (TP4)
Readjust SW1 and SW2 if the signal at LISTEN (TP4) is over 0.5Vp-p.
A.2Detailed Tuning in V Mode
Follow step A.1 to fine tune SW1 and SW2 without checking sensitivity.
A.3Detailed Tuning in VI Mode
Follow step A.1 to fine tune the C/PT IX in VI mode for deactivation. If phantoms occur, reduce
the sensitivity by adjusting GAIN (R4) counterclockwise all the way.
