• (digital channels only)
Unlike analogue 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
analogue 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 your antenna to
increase the signal strength. Continue to adjust the antenna until you find the best position
with the strongest signal.
Software Upgrade •
Insert a USB drive containing the firmware upgrade downloaded from samsung.com into the TV.
Please be careful not to disconnect the power or remove the USB drive while upgrades are being
applied. The TV will turn off and turn on automatically after completing the firmware upgrade.
Please check the firmware version after the upgrades are complete (the new version will have a
higher number than the older version).
When software is upgraded, video and audio settings you have made will return to their default
(factory) settings. We recommend you write down your settings so that you can easily reset them
after the upgrade.
