DVB Conditional Access System (CAS) 
Option 
This following Appendix describes the procedure for inserting a DVB Conditional Access (CA) Module and Smart Card 
(SC) into an SFX----B series receiver, and the related Web GUI operation. You will need to be certain that your model 
of receiver can accommodate the appropriate type of CA Module and/or SC, depending on the DVB CAS being used 
in your network. 
Pre-installation Procedure 
Prior to inserting a CA Module and/or SC into the slot on the rear panel of your receiver; please take note of the 
following precautions: 
•  Do not bend or twist the card. 
•  Keep the card out of direct sunlight or other heat sources. 
•  Do not remove/insert the card repeatedly into the slot. 
•  Clean the card only with a soft dry tissue. Do not use liquids or detergents to clean the card. 
•  Record the card number for future reference in case the card is damaged or lost. If the card is damaged or 
lost, contact your service provider for a replacement. 
•  Use caution when inserting the CA Module and/or SC. The size of the slot opening is quite small. Ensure 
that the CA Module or SC has been aligned correctly with the connector inside the receiver. 
Inserting the CA Module 
There is one slot on the rear panel of a SFX----B series receiver that provides a location to insert a DVB Common 
Interface compliant CA Module and Smart Card combination.  To access this opening, you must remove the rear panel 
option plate, by unscrewing the 3 Philips type screws, as shown in Figure D- 1.
