The adapter (CI module) for the HD card (to receive the private HD channels: Sat1, Pro7, RTL ...) flat screen TV was a Samsung UE55D6200TSXZG 138 cm (55 inches) 3D LED backlight -TV (Full HD, HD ready with 3D, 200Hz CMR, DVB-T / C / S2, CI +) black purchased, as the CI module was not part of the supplied TV-accessory, but there was a HD card already available , For TV was only an extra-to-install bracket in the accessory case, which was simply clicked into the rear wall. The HD card is similar to a bank card for a card reader in the CI module ("right side up" - otherwise it will not work). The CI module fitted in the Samsung-mount and worked right away after the TV had the CI module mounted (on-screen message). Since the image quality of HD channels concerned, if it is transmitted in HD. However, the unit or the HD card, or television always needs a little adjustment time of about 5 seconds until the station is visible. Maybe you can at initial purchase and the jointly offered with the HD card CI module use (priced only slightly cheaper). After one year, then the HD card needs to be replaced. Recommended to buy!
