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

300-ohm twin-lead cable (fl at)

F-type connector

75-ohm coaxial cable (round)

75-ohm coaxial cable

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.)

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.

•  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.
