the optional SPS battery.
If the battery voltage is above a
minimum level, the system runs the
power-up self-tests. If the battery voltage
is low, the IFP displays the STANDBY

enters the standby mode. To continue,
press the Run/standby key once and the
Speaker key twice.

The system also displays the results
of these tests on the console terminal

display. The following sections describe
how to interpret the results of the power-
up tests from the console terminal or
