How to get the most enjoyment from your color TV set
Your new color TV incorporates a host of features designed to give you excellent performance. Besides, this model utilizes a highly sophisticated control microprocessor that can give you unprecedented convenience and control in the areas of picture adjustment, channel tuning, monitor operation, on-screen information, and remote control.
We therefore strongly urge that you read all of these instructions before using your TV for the first time.
Installation
Antenna
Unless your TV is connected to a cable TV system, or to a centralized antenna system, a good outdoor color TV antenna is recommended for the best performance. However, if you are located in a strong signal area that is free from interference and ghost conditions (multipath), an indoor antenna may be sufficient. The two pole antenna packed with this set is for your convenience only. It is not capable of providing you with the sharp detail and rich color that this television was designed to display.
Location
Select an area where sunlight or bright indoor illumination will not fall directly on the picture screen. Also, be sure that the location selected allows a free flow of air to and from the perforated back cover of the set.
Note
Never remove the back cover of the set. This can expose you to very high voltage and other hazards.
If the set does not operate properly, unplug it and call your dealer or service shop.

According to the text, the new color TV set “incorporates a host of features” (first paragraph). This means that the new color TV set has:
• usado em vários padrões de canais de broadcast sem fio (celular, satélite etc.);
• todos os usuários compartilham a mesma frequência, mas cada um tem a própria sequência de “chipping” (ou seja, código) para codificar dados;
• decodificação: produto interno entre sinal codificado e sequência de chipping;
• permite que múltiplos usuários “coexistam” e transmitam simultaneamente com o mínimo de interferência (se os códigos forem “ortogonais”).
