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.
Press the ▲ or ▼ button to select Signal Strength, then press the ENTER button.
2 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.
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.
Press the ▲ or ▼ button to select LNA, then press the ENTER button.
2 Press the ▲ or ▼ button to select Off or On, then press the ENTER button.
Press the EXIT button to exit.
➢ If the picture is noisy with the LNA set to On, select Off.
➢ The LNA setting must be made separately for each channel.
