equipment, be sure the antenna system is grounded so as to provide some protection against
voltage surges and built-up static charges.
For added protection for this television equipment during a lightning storm, or when it is left
unattended and unused for long periods of time, unplug it from the wall outlet and disconnect
the antenna. This will prevent damage to the equipment due to lightning and power-line surges.
An outside antenna system should not be located in the vicinity of overhead power lines or other
electric light or power circuits, or where it can collide with such power lines or circuits. When
installing an outside antenna system, extreme care should be taken to keep from touching such
power lines or circuits, as contact with them might be fatal.

Connecting the Antenna
Connecting CATV
Your DV3750 LCD Display has an internal 75 ohm coaxial cable connector, so antennal hook-up
is very easy.When connecting a 75-ohm coaxial cable, secure it firmly to the antenna connector.
Some cable TV companies provide "pay per view" programming. Since the signal for these paid
channels is encoded, most cable TV companies provide their own tuners/ decoders. You must
install a tuner/ decoder to be able to view locked encoded programming. If you require special
instructions on how to install cable service, please contact your cable TV provider. The tuner/
decoder provided by your cable TV company can be used according to the following
instructions.
You must have an RF switch with two inputs (A and B).
The "A" input on the RF switch allows you to use the display's CH / buttons to view
unlocked channels. The "B" input on the RF switch allows you to use the channel selection
button on your cable box to view locked encoded programming via the tuner/decoder.
Antenna
The antenna equipment has far more effect on reception for color TVs than on black and white
models. We suggest you use a good-quality outdoor antenna. Following are simple explanations
for the connection of various types of antennas.
1. Generally speaking, 75 ohm systems have a
round cable with an F-shaped connector
which requires no tools. Attach the cable
directly to the input.
2. 300 ohm systems have a flat "dual lead" type
cable. A 300-75 ohm transformer may be
used to attach the antenna to a 75 ohm
input.
