Please read the following safety instructions carefully to avoid damage to persons or the product during use. Also obey the instructions in your PC manual.
Please provide the manual to people who carry out an upgrade or upgrade (also in case of resale).
Important safety instructions
- Installation requires knowledge with PC systems and may only be carried out by experienced users and trained staff.
- Never allow children to play with electrical appliances. They can not recognize hazards.
Disconnect your PC from the power supply before doing any work, and then wait a few minutes for all components to cool down before performing any work. There is a risk of electric shock when connecting to the power supply, which can be fatal.
- The power plug must be accessible in order to allow disconnection from the power supply in case of danger.
- Never bridge connections in the system or the power supply fuse, as there is a risk of electric shock.
Hazard information to work on your PC
- Do not plug or unplug any cables when the PC is switched on (not even the antenna cable).
- You should statically discharge prior to any work, for example by touching a grounded object.
- Use only components and cables in perfect original condition. Defective devices and cables must be replaced.

Please consider the following advice, once a problem regarding your card occurs. Please access our knowledge base for more information and assistance at: http://support.digital-devices.de/
Basic prerequisites / testing for errors
Turn off the PC and disconnect the power cord before carrying out any checks.
Now perform the following checks:
- Are all cables and connectors properly connected?
- Is the card firmly plugged into the PCIe slot?
- If the card is not recognized by the system, please try another PCI Express slot. Since some motherboards don't recognize cards plugged into a PCIe X16 slot properly. Utilizing the X4 or X1 slot should be considered.
- Make sure using original equipment only. Do not interchange cables from different devices, even though they appear identical. They may differ in pin configuration.
- Does the antenna provide adequate antenna power?
- Make sure to implement a minimum distance of one meter to high-frequency and magnetic interference sources (TV set, mobile phone, speaker boxes, etc.).
- Turn the PC back on and carry out the following checks:
- Does the card show up in the device manager or in case of a Windows PC in the Digital Devices control Center?
- Inside BIOS, "PCI Express overclocking" should be set to 100 and not into "auto" mode.
- Does the DD Control Center or your application display a signal?
- Does the problem occur in one application only? Try it out in Digital Devices TV as well.
- Is the installed driver up-to-date? Does the problem still occur when a different one is used?
- Did you install the required codecs for playback on your system? Disable DXVA if block graphics occur with HD stations.
DVB-C specific tests
Is a signal detectable at the connector and is the signal unencrypted? Many provider utilize basic encryption, which makes a CI module with CAM mandatory for many stations.
- Can you watch the channels with other devices?
- Can you watch the television program of public broadcasters, which tend to be transmitted without encryption.
