There are several small ventilation holes on the top of the specimen. There is also a power indicator on the case, several antenna jacks.

In order for the set-top box of this manufacturer to be able to fully function, it must be connect and configure... First you need to connect the antenna cable, because the receiver will decode and process the signals that are received by the antenna and transmitted from it to the TV. After that, you should make a connection to the screen. Further technology depends on the specific model of consoles, since they differ from each other in some important design features.

For connecting model CDT-1711SB, in which several outputs are provided at once, it is desirable to have an HDMI connector on the TV. If it has only RSA inputs, then you will have to additionally use special "tulips", two of which will serve to transmit audio signals, and one more will be needed to transmit the image.

If you decide connect a TV set-top box CDT-100 with the provided HDMI output, which provides the highest quality image on the TV, then the best option would be to connect to equipment that has a similar connector. In such cases, it will be possible to use only the appropriate cable - most often it is included with the device, but it can also be purchased separately at any electronics store.

If the TV only has an RSA input, then you will have to additionally buy a signal converter. It is through it that the TV set-top box is connected. Sometimes this model is connected using an antenna input.

After that, the prefix follows tune... To do this, check if the connection is correct. On the TV, a mode is selected for display, which must correspond to the type of connection, that is, HDMI, SCART, AV. When you turn it on for the first time, an auto search for TV channels is done.

In order for such an autosearch to be performed, the country and language should be specified in the settings window (will open automatically). And also there you need to select the "open channel" function.

The receiver will scan the frequency range, and then will be able to store all those channels that were found. The settings menu will then close automatically.

Such set-top boxes also provide for manual channel search.... Most often it is required in cases where the connection points are located too far from the TV tower.

To perform manual tuning, you first need to use an interactive map (CETV) to find out the exact frequency of operation of such television in the region. After that, the menu of the device is opened and the section "Search for TV channels" is found, there they press the option "Manual search" and indicate the value of the frequency band.

The receiver will scan this frequency later. It will detect all available channels and then save them.
