Signal Strength (Digital)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.If the signal strength meter indicates that the signal is weak, physically adjust yourantenna to increase the signal strength. Continue to adjust the antenna until you findthe best position with the strongest signal.Software UpgradeSamsung may offer upgrades for your TV’s firmware in the future.
