SELF TEST (continued)
If "TRAFFIC ADVISORY SYSTEM TEST FAILED" is heard or the
SKY497 FAILED screen appears, the SKYWATCH system should be
turned OFF.
The operator initiated Self-Test can only be
performed when in standby or failed mode.
STANDBY CHARACTERISTICS
The SKYWATCH system will display STANDBY when in the standby
mode. Selecting OPR activates the system and changes the display from
the Standby screen to the Above (ABV) mode and 6 nm range. The ranges
available are 6 nm, 5 nm, and 2 nm, and are selected by pressing the
Display Range Button.
To go back into Standby, select STBY mode. The system will go to the
STANDBY screen and will not track targets again until the system is
manually switched out of Standby.
The Self Test works while in the Standby screen by pressing the Menu
Button and selecting Self Test.
The SKYWATCH system, while in flight or operating on the ground, will
display 4 altitude display modes. These are: Above (ABV), Normal
(NRM), Below (BLW), and Unrestricted (UNR). These modes are
accessed through the GNS selector knobs. Refer to the SKYWATCH
