Checking the Digital-Signal Strength Unlike analog channels, which can vary in reception quality from "snowy" to clear, digital (HDTV) channels have either perfect reception quality or you will not receive them at all. So, unlike analog channels, you cannot fine tune a digital channel. You can, however, adjust your antenna to improve the reception of available digital channels. Clear Scrambled Channel 1 Press the MENU button to display the menu. Press the ▲ or ▼ button to select Channel, then press the ENTER button. Fine Tune Signal Strength ► Channel 2 Press the ▲ or ▼ button to select Signal Strength, then press the ENTER button. If the signal strength meter indicates that the signal is weak, physically adjust your antenna to increase the signal strength.
