How to use

Plug the unit into a 230 V AC mains outlet and turn it on; use the on-screen menu to scan for available DVB-T2 channels. Adjust antenna position for optimal signal strength and use the LED display and on-screen information to confirm channel reception. For audio, ensure the TV or receiver is configured to accept Dolby Digital Plus streams if available from the broadcast.

Recommendations

Place the antenna as high and as free from obstructions as possible to improve terrestrial signal reception. If reception is weak, try repositioning the antenna or using a higher-gain external antenna. Keep the set-top box ventilated and avoid covering the vents to maintain normal operating temperature. If the TV does not automatically switch to the best audio format, check TV audio settings to enable passthrough or compatible decoding for Dolby Digital Plus.
