OPERATING MODES
The videodisc player may be operated in any of three modes:
Manual,
Automatic, or programming.
Each mode is briefly described below.
A.
Manual Mode
Manual Mode is initiated by inserting a disc, closing the
drawer, and giving the PLAY command.*
Assuming that the
videodisc does not contain a program dump (or that the
Audio 2 channel is OFF, which instructs the player to
bypass looking for the initial program dump), the disc
may be played from beginning to end (or up to the first
Picture stop, if any exist on the disc) without any further
action by the viewer.
However, the presentation of the
material may be changed at any time through the use of
the EC! or RCU to direct the player.

The REJECT command causes videodisc
rotation to slow to a stop, and the player to return
to the PARK position.

Upon recelvlng the RUN command,
the player enters Automatic Mode and begins executing
the application program stored in RAM.
o

If Audio
channel 2 is "ON", and a disc containing one or more
program dumps "spins up", the player loads the initial
program dump into RAM.
When the load is completed,
the player begins executing the program.
o
Programming Mode Select.
If the player receives
the PROGRAM command, any play in progress stops in
a freeze-frame and the player enters Prog£amming
Mode.
* The videodisc player is equipped with a switch-selectable
"Auto-Play" function that automatically begins play of the
videodisc after the power is turned on when the drawer
is closed.
