Installing the Control Unit
Step 1: Modifying the Processor for Key Mode
CAUTION:
■ This procedure is part of a larger procedure for installing the
processor. If you have not already read the beginning of this
section, “Installing the Processor,” do so before continuing.
■ This procedure must be performed for KF registration with the
FCC.
■ This procedure prevents the system from being programmed
as a Hybrid/PBX system. Do this only if the system is
programmed for Key mode and GS trunks are not indicated
on Form 2c, System Numbering—Trunk Jacks.
Otherwise, skip to the next section, “Step 2a: Installing the
Feature Module.”
a. Remove the processor from its package.
b. Put the processor on a flat surface.
c. If the feature module is installed, remove it as indicated later, under
“Step 2b: Replacing the Feature Module.”
CAUTION:
Do not touch the HDR3 header on the processor board, which
is exposed when the feature module is not instal!ed in the
processor. If the HDR3 header is removed, the system
programming may be deleted and have to be restored.
See Figure 2-12.
