4.4 Initial Channel Scan
- Turn on your television and select the correct input source (e.g., S-Video, AV, HDMI) corresponding to your connection.
- Press the POWER button on the converter box or remote control to turn on the unit.
- The first time you power on the unit, an initial setup wizard may appear. Follow the on-screen prompts to select your language and country.
- Initiate an automatic channel scan. This process will search for available digital channels in your area. This may take several minutes.
- Once the scan is complete, the converter box will tune to the first available channel.
5. Operating Instructions
5.1 Power On/Off
Press the POWER button on the front panel of the converter box or on the remote control to turn the unit on or off.
5.2 Channel Selection
- Use the CH+ and CH- buttons on the remote control to navigate through channels sequentially.
- Enter the desired channel number directly using the numeric keypad on the remote control.
5.3 Volume Control
Adjust the volume using the VOL+ and VOL- buttons on the remote control. Note that the primary volume control may still be on your television.
5.4 Menu Navigation

5.5 Analog Pass-Through Feature
The DT250A allows you to watch both digital and analog channels. If you have an analog antenna connected to the ANT OUT port (or if the converter box is off), your television can receive analog signals directly. When the converter box is on, it processes digital signals. Consult your TV's input settings to switch between the converter box output and direct analog antenna input if you wish to view analog channels directly through your TV.
6. Maintenance
- Cleaning: Ensure the unit is powered off and unplugged. Wipe the exterior surfaces with a soft, dry, lint-free cloth. Do not use abrasive cleaners, waxes, or solvents.
- Storage: If storing the unit for an extended period, disconnect it from power and store it in a cool, dry place away from direct sunlight and extreme temperatures.
