NOTE!
If "AUTO EQ MUL = ##" is displayed, the system is already set for Automatic Equalize. In this
case, you can proceed with steps 5) through 8) to change the current setting, or proceed with step 9) if
no changes are required.
NOTE!
If "END AUTO ##.##HR" is displayed, the system is already set for Automatic Equalize, and an
Automatic Equalize is in progress. In this case, you can proceed with steps 5) through 8) to cancel the
Automatic Equalize in progress and change the current setting, or proceed with step 9) to proceed with
the Automatic Equalize in progress and make no changes.

NOTE!
Auto Equalize is canceled and the system is placed in the float mode if any of the following
occurs.
• Manually placing the system in the float mode by navigating to and activating "SET FLOAT MODE"
menu item in the MCA Function Menu.
• Resetting the "AUTO EQ MUL = ##" value in the MCA Configure Menu when "END AUTO ##.##HR" is
being displayed, as described in the previous procedure
• Applying an external test/equalize signal.
Method 4 (External Test/Equalize) Procedure
In this method, a user (or external equipment) places the system in the test/equalize mode by applying an
external signal to the system. The system returns to the float mode when the external signal is removed. This
method overrides the other three methods.
Placing the System into Test/Equalize Mode:
Apply system ground to the system's external test/equalize
terminal.
Remove system ground from the test/equalize terminal.
