Refer to Table 7-1.
KPA
operating problems can be identified by first observing the status indicators on the
front panel. When a fault condition is indicated, the specific fault, or faults, can be
identified in the

the local operation keypad and displayed on the LCD display located on the front panel.
The status of

Refer to Section 4, Operation, for a description of the KPA command functions; also,
check the status of the mute condition in the configuration menu (i.e.: Mute = “On”
means that the amplifier will be muted.)
