Customizing the Format Display Screen
FORMATS
Press the
FORMATS
key to return to
the format selection screen.
Notice that a small indicator (
CUST
)
now appears next to the Current Format
area, indicating that “
Custom
” screen
mode is active.
Any fader settings and projector
selections are also displayed. In this
example, the screen tells you that the
fader setting has been adjusted to
6.5
and
Projector 1
has been selected.
A.2 Saving System Settings
It is possible to send the CP500 system parameters into a computer before
replacing or moving the unit, or installing a repaired Cat. No. 684 board. Also,
software upgrades for the Model CP500 are sometimes accomplished by
distribution of new FLASH EPROMs. In order to avoid having to re-equalize the
theater after any of these operations, the existing CP500 system parameters can be
saved on a computer, then sent back to the new EPROMS or replacement unit.
We
strongly suggest that the current CP500 system settings be saved to a disk
after each installation.
Saving the CP500 system settings can be accomplished by using the terminal
program in Windows
®
or by using Dolby Laboratories’
Load500
software.
A.2.1 Using the Terminal Program in Windows
