How do I properly insert a CI+ CAM module into the TV?

Look on the CAM for the correct insertion method to avoid damage. While looking at the back of the TV with the front of the CAM facing toward you, gently insert the CAM into the PCMCIA CARD SLOT and push it in as far as it will go. Leave it in the slot permanently. It may take a few minutes to activate after switching on the TV.
