Preparation

Using the remote control unit

Use the remote control unit by pointing it towards the remote control sensor on
the TV. Objects between the remote control unit and the remote control sensor
may prevent proper operation.

Cautions regarding remote control unit

• Do not expose the remote control unit to shock.
In addition, do not expose the remote control unit to liquids, and do not place in an area
with high humidity.
• Do not install or place the remote control unit under direct sunlight. The heat may cause
deformation of the remote control unit.
• The remote control unit may not work properly if the remote control sensor on the TV is
under direct sunlight or strong lighting. In such cases, change the angle of the lighting
or the TV, or operate the remote control unit closer to the remote control sensor.

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.
1. A 75-ohm system is generally a round cable with F-type
connector that can easily be attached to a terminal
without tools (Commercially available).
F-type connector
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 (Commercially available).

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.)
