Antennas
To enjoy a clearer picture, use an outdoor antenna. The following is a brief explanation of the types of connections
that are used for a coaxial cable. If your outdoor antenna uses a 75-ohm coaxial cable with an F-type connector,
plug it into the antenna terminal at the rear of the TV set. For connecting the antenna cable to the TV, use
commercially available cables.

Installing Batteries in the Remote Control Unit
If the remote control fails to operate TV functions, replace the batteries in the remote control unit.
1 Open the battery cover.
2 Insert two “AAA” size batteries (supplied with
the product).
• Place the batteries
with their terminals
corresponding to the (
e
)
and (
f
) indications in the
battery compartment.
3 Close the battery cover.
CAUTION
Improper use of batteries can result in chemical leakage or explosion. Be sure to follow the instructions below.
• Do not mix batteries of different types. Different types of batteries have different characteristics.
• Do not mix old and new batteries. Mixing old and new batteries can shorten the life of new batteries or cause chemical leakage
in old batteries.
• Remove batteries as soon as they are worn out. Chemicals that leak from batteries that come in contact with skin can cause a
rash. If you fi nd any chemical leakage, wipe thoroughly with a cloth.
• The batteries supplied with this product may have a shorter life expectancy due to storage conditions.
• If you will not be using the remote control unit for an extended period of time, remove batteries from it.

1. A 75-ohm system is generally a round cable with F-type connector
that can easily be attached to a terminal without tools.
2. A 300-ohm system is a fl at “twin-lead” cable that can be attached
to a 75-ohm terminal through a 300/75-ohm adapter.

NOTICE
When connecting the RF cable to the TV set, do not tighten F-type
connector with tools.
If tools are used, it may cause damage to your TV set. (The breaking
of internal circuit, etc.)
F-type connector should be fi nger-tightened only.
