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.
LNA (Low Noise Amplifier)
If the TV is operating in a weak-signal area, sometimes the LNA function can improve the reception (a low-noise preamplifier boosts the
incoming signal).
1. Press the MENU button to display the menu.
Press the or buttons to select "Channel", then press the ENTER
2. Press the or buttons to select "Signal Strength", then press the ENTER
If the signal strength meter indicates that the signal is weak, physically adjust
your antenna to increase the signal strength.
Continue to adjust the antenna until you find the best position with the strongest signal.
