Instructions
Connect a joystick to the "Player 1" port of the console, and another, if available, to the "Player 2" port.
Plug the coaxial plug of the console into the "Aerial" port of the television. If an aerial is already connected to this port, remove it and connect the aerial to the console's switcher box.
Turn on the television and tune to channel 3 or 4.
Turn on the Atari 2600 with a cartridge inserted and open the television's "Channel" or "Tuning" menu. Select the option to manually search for new channels, usually called "Manual Tune" or "Search."
Search through the UHF band until the television finds the video signal from the Atari 2600. Select "Store" or "Lock" to add the channel to the television's memory. The console should be ready to play.
