2.2 Normal Operation
This section describes the normal operation of the CP650. Section 2.3 describes
operation when the CP650 has switched to emergency bypass.
2.2.1 Power On
Each time the CP650 is connected to power, it automatically sets itself to the selected
wake-up state. During the CP650 installation, the power-on state of the unit was
configured from the following choices:
• Projector 1 or 2 (selected by the installation technician).
• The last fader setting before shutdown. (If the front-panel fader was active, the
system will start up at the last fader setting before power was turned off. If the
auditorium fader was active, the system will read the setting of the auditorium
fader knob.)
• Either the film sound format that was active when power was turned off or the
film sound format previously stored as the power-on format. (The format options
can be set using the procedure described Section 2.2.10.)
If power has been removed for longer than approximately three weeks, the CP650
wake-up state is:
• Front-panel main fader activated and set to 7.0
• Format 10 (Dolby Digital)
• Power-on format set to the last format used before power was turned off
When power is first applied, the first screen shows that the
software is loading into the CP650 memory, and displays
the software version number.
Next, a brief self-test of various internal circuitry is
automatically performed.
Finally, the normal operating screen appears. Details on the
items displayed are described earlier in this chapter. This is
the only screen you will need to see for ordinary operation.
