PROCEDURE
KEYLOCK OPTION
1. An optional KeyLock feature is available
from PACE which prevents unauthorized
alteration of stored data or calibration of
the system. Check the rear panel of the
system power source. If the KeyLock
feature is present there will be a KeyLock
switch located in the upper left portion of
the panel. Use the key to turn the switch
to the “Unlock” position. If the feature is
not present, there will be a round plastic
filler plug present at that location.
NOTE
The KeyLock switch must be turned to the “UNLOCK” position to alter any
of the data stored in memory or to recalibrate the system.
