DUAL ANTENNA SCANMAX PRO DEACTIVATOR CONTROLLER 

8200-0365-01, REV. 1A 

INSTALLATION AND SERVICE GUIDE 

10 of 12

 

Use this procedure only when the following occurs: 
•  Unit is not deactivating labels 
•  Unit false fires 
•  Deactivation height is very low 

Equipment required: EAS non-deactivateable 
label, laptop with minimum Window 98 SE, service 
configurator, RS232 programming cable (standard 
Ultra•Max CE cable). 

Be sure you have completed basic troubleshooting 
before using this procedure. If troubleshooting is 
still necessary, turn on the controller and connect 
the RS232 cable to your serial port and the POS 
1/SERV port of the controller. 

Note: As indicated in basic troubleshooting, a solid 
red light on the status indicator is non-repairable at 
the customer site. Return the unit to the service 
center for repair. 

Note: If swapping out the controller for a new one, 
no set-up is required. Simply plug in all cables and 
turn the unit on. Inform the customer that the unit is 
“advance replaceable” and that a service call is not 
necessary. 

If basic troubleshooting has been completed and 
the green LED is still blinking: 

1.  See if a non-deactivateable label (hard tag) is 

within 30.5cm (12 in) of the antenna. 

2.  On the set-up screen for the antenna being 

tested, disable Hard Tag Check and ensure 
Detect Only is not enabled. 

3.  Unplug the DC power supply from the ac outlet 

and then plug it back in. If deactivation occurs, 
there is a non-deactivateable label or hard tag 
within the deactivation area preventing normal 
operation. Remove the label or hard tag. 
Note: If the label causing the problem cannot 
be found, swap the controller with one from an 
adjacent register. If the problem continues, 
something within the checkout area responds 
to the detection field like a label and the Hard 
Tag Check mode must remain disabled for 
operation. If the unit still does not deactivate, 
return it for service. 

1.  Re-sync the controller by pressing the Re-Sync 

button on the configurator. Be sure 
AUTOSYNC is enabled. If false firing  
stops, troubleshooting is complete. 

2.  Remove the antenna and rotate it horizontally 

and vertically until deactivation stops. Rotate 
the antenna again until deactivation begins. 
This is the direction of interference. 

3.  Reposition equipment that may be causing 

interference such as card readers and 
displays. Typically, most POS equipment 
should be 30.5cm (12in) from the antenna. 

4.  If false firing stops, troubleshooting is 

complete. If false firing continues, do the 
following: 

 

On the setup screen make sure that 
Detection Compensation is set to 0. If false 
firing continues, go to the next bullet. 

 

On the diagnostics screen of the 
configurator, look at the noise levels. If 
possible, rotate the antenna until the noise 
is minimized. 

 

Adjust the threshold level on the 
configurator down one-step-at-a-time until 
false deactivation stops. Set the threshold 
one step higher. Troubleshooting is 
complete. If false deactivation  
continues go to next step. 

It is possible that the metal counter or mounting 
bracket is affecting the detection field. 
On the configurator, while holding a tag above the 
center of pad, adjust Detection Compensation 
negative until firing occurs only when tag is at or 
below the deactivation height set on the 
configurator. 

On the configurator adjust the Detection 
Compensation negative. If false deactivation stops 
and the deactivation height is OK, troubleshooting 
is complete. If not, return the controller for service.
