GENERAL INFORMATION
The BH7514 can be powered by either 6 "C" cells or an
optional AC to DC voltage adaptor.
The BH7514 features games of "Tennis", "Hockey",
"Smash" and "Practive", with ski II levels from" Amateur" to
"Professional" using "Ball Speed", "Ball Angle", and
"Player Size" for the more demanding enthusiast. Serving
can be either "Manual", by depressing the "Serve" button
or "Automatic". Automatic features include "on-screen"
scoring which awards a point to the appropriate player or
team each time the ball leaves the playing area. "Automatic
Serve" will return the ball into play from the side that was
awarded the point. This sequence will be repeated until a
score of "15" is reached by one side, after which the ball
will continue to bounce around with no further hits or
scores. Depressing "Reset" will change the score to
indicate "0"-"0" and the ball will be served randomly from
the left or right side.
During play three audio tones will be generated to indicate
that the ball has touched the top or bottom walls, the
player has hit the ball, or that a score has been made.

TYPICAL OPERA-Tl ON (TENNIS)
Connect the 300 oh·m twin-lead of the "Antenna-Game"
switch to the VHF antenna terminals of a properly operating
television. Connect the VHF antenna wires (if used) to the
"Antenna-Game" switch terminals. When changing from
game to television, make sure that the "SI ide-Switch" is
moved to the extreme position, do not leave the "Slide-
Switch" in the mid-position. Plug the game cord from the
Odyssey into the "Antenna-Game" switch socket and place
the "Slide-Switch" to the "Game" position. Place the
"Channel Switch" located in the battery compartment in
either the Channel 3 or Channel 4 position. The "Channel
Switch" is for selection of the unused channel of VHF in
your area.
Set the "Game Selector" to a position so that the double
arrow is indicating your choice of games by name and
picture. Turn the television and Odyssey On. Push "Reset"
so that the score and ball will be in the starting position.
Fine tune the television if necessary. Select desired "Ball
Serve", "Ball Speed", "Ball Angle", and "Player Size ''.
The Odyssey is now ready for the game to begin. Control
of the players is accomplished by rotating the "Player
Controls" that are detachable. When either contestant
reaches "15" points there will be no control of the ball and
a new game will have to be started.
