5. Operating Instructions
5.1 Channel Navigation
Use the CH+ and CH- buttons on the remote control or the front panel to change channels. Alternatively, use the numeric keypad on the remote to directly enter a channel number.
5.2 Recording (PVR Function)
The DIGIQUEST Twin Tuner REC features a dual independent tuner, allowing you to record two channels simultaneously, even if they belong to different multiplexes (MUX), without requiring a second antenna cable. The tuners work autonomously to provide maximum recording flexibility.
- Initiate Recording: While watching a program, press the REC button on the remote control to start recording.
- Record and Watch: You can watch another channel or a saved recording while a program is being recorded. To view a recording already in progress (started a few minutes ago), simply press the BLUE (INFO) button on the remote control.
- USB Device Recommendation: For stable recording, use USB 2.0 or 3.0 devices formatted in FAT32 or NTFS. You can format directly from the 'HDD' menu of the decoder for optimal compatibility. The decoder automatically analyzes the USB drive upon connection and will alert you if the write speed is too low or if there are issues.
5.3 Timeshift (Live Pause)
The Timeshift function allows you to pause a live program and resume it whenever you want. You can also rewind to re-watch a recently aired scene.
- Activate Timeshift: Press the PAUSE button during live TV to pause the program.
- Resume/Fast Forward/Rewind: Use the playback controls (Play, Fast Forward, Rewind) on the remote to manage the paused content.
5.4 Media Playback
The decoder supports playback of various media formats (video, audio, images) from a connected USB device.
- Access Media Player: Navigate to the 'Media Player' option in the main menu.
- Browse Files: Select your USB device and browse through your stored files.
- Supported Formats: WAV, WMA for audio; common video and image formats are also supported.
6. Troubleshooting
If you encounter issues with your DIGIQUEST Twin Tuner REC Decoder, please refer to the following common solutions:
