BH7510 ODYSSEY
GENERAL INFORMATION
The BH7510 can
be
powered by either 6 "C" Cells or an
optional AC to DC 9 volt adaptor.
The BH7510 features games of Smash, Tennis, Hockey
and Practice and as an extra challenge has switchable skill
levels of amateur and pro which automatically adjust player
size, and speed of the ball. Deflection of the ball is
determined by where it strikes the player.
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. After either side has scored 15 points the ball
will continue to be served but neither player will be able to
return it.
During play a different audio tone is generated each time
the ball hits a player, a wall, or a point is scored_ No
provisions are made to turn the sound on or off.
