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 to display the menu.
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.
Press the EXIT button to exit.
You can also press the ENTER button to select OK then press the EXIT button
to exit the menu.
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 ▼ 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.
Press the
EXIT button to exit.
➢ LNA functions only when antenna is set to Air.
(See “Selecting the Antenna” on page 38)
➢ If the picture is noisy with the LNA set to On, select Off.
➢ The LNA setting must be made separately for each channel.
