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.
1
Press the MENU button. Press the or button to select “Channel”,
then press the ENTER button.
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.
Continue to adjust the antenna until you find the best position with the
strongest signal.
Select “Return” by pressing the or button, then press the ENTER
button to return to the previous menu. Press the EXIT button to exit.
Digital
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. Press the or button to select “Channel”,
then press the ENTER button.
2
Press the or button to select “LNA”, then press the ENTER button.
3
Press the or button to select “Off” or “On”, then press the
ENTER button.
Select “Return” by pressing the or button, then press the ENTER
button to return to the previous menu. Press the EXIT button to exit.
The LNA setting must be made separately for each channel.
If the picture is noisy with the LNA set to On, select Off.
