Connecting to TV or Cable TV
1. Confirm your display is equipped with a TV tuner. You can
tell by looking at the connection jacks located on the back of
the display. If there is a threaded-screw type of connector
(called the RF connector), then you have a TV tuner. If you
do not see this type of connector, then you do not have a TV
tuner installed.
2. Connect the RF cable from the antenna or cable socket to
the RF connector labeled as “ANT” on the back of the dis-
play.
Notes:
You can still receive TV or Cable TV reception without the
TV tuner if you have a VCR with a built-in TV tuner con-
nected to the back of the display. See instructions included
in your VCR for instructions on how to attach a VCR to this
display.
Important Safety Instructions: Outdoor Antenna Grounding
If an outside antenna or cable system is connected to the TV
receiver, be sure the antenna or cable system is grounded so
as to provide some protection against voltage surges and
built-up static charges.
Section 810 of the National Electrical Code (NEC) provides
information with respect to proper grounding of the mast and
supporting structure, grounding of the lead-in wire to an
antenna discharge unit, size of grounding conductors, loca-
tion of antenna discharge unit, connection to grounding elec-
trodes, and requirements for the grounding electrode.
Example of antenna grounding as per National Electrical
Code is as the right picture.
