Run the Self Test
Run the Operator-Initiated Self Test
It is recommended, but not required that you run the operator-

you get a failed screen.

in standby or failed mode, press the
TEST
button.
The
SKY497
begins its
self test and the test
screen (figure

)
appears. Upon
successful
completion
of the self test, you
will hear “
T
raffic
advisory system test
passed” and the
display will revert to
the previous standby
or traffic screen.
2. If you hear “

raffic
advisory system test
failed” or see a
SKY497
failed screen, push the
TEST
button
again. If it fails again, refer to the

seeing the test screen, and the

BRT
, turn off the

Switch Between Standby & Operating Mode
When you’re on the ground, you must manually switch out of
standby if you want the
SKY497
to display traffic information.
The ability to switch out of standby on the ground in conjunc-
tion with the
above
display mode is especially useful for scan-
ning the airspace around the airport before takeoff.
1. To manually switch into operating mode from the standby
screen (figure
3-2
), press the button labeled
>
OPR
