16 Chapter 2 Installing the LCD TV
This reminder is provided to call the CATV system installer’s attention to Article 820-40 of the
National Electrical Code (NEC) that provides guidelines for proper grounding and, in particular,
specifies that the cable ground shall be connected to the grounding system of the building
accurately, or as close to the point of cable entry as possible. Use of this TV for other than
private viewing of programs broadcasted on UHF, VHF or transmitted by cable companies for
the use of the general public may require authorization from the broadcast/cable company, and/
or program owner.

Cable TV (CATV) Connection
■ The RF switch (not included) is required to provide two inputs (A and B). Setting
the RF switch to position A allows viewing of all unscrambled channels by using
the TV channel keys.
■ Setting the RF switch to position B allows viewing of all scrambled channels via
the converter/descrambler by using the converter channel keys.
■ A 75-ohm coaxial cable connector is built into the set for easy hookup.
When connecting the 75-ohm coaxial cable to the set, connect the 75-
ohm cable into the ANT. terminal.
■ Some cable TV companies offer premium pay channels. Since the
signals of these premium pay channels are scrambled, a cable TV
converter/descrambler is generally provided to the subscriber by the
cable TV company.
This converter/descrambler is necessary for normal viewing of scrambled channels.
(Set your TV to channel 3 or 4, typically one of these channels is used. If this is unknown,
consult your cable TV company.)
For more specific instructions on installing cable TV, consult your cable TV company.
One possible method of connecting the coverter/descrambler provided by your cable TV
company is shown in the diagram below.
