OPERATION
POWER-UP
At power-up, the WX-500 performs a power-up self test. The self test
takes about 25 seconds to ensure that all major WX- 500 functions,
including antenna reception, memory, and microprocessor functions,
are operating properly. An error message is displayed if a fault is
detected. Refer to the Error
Messages section later in this chapter for
more information.
INTRODUCTION
The MFD controls the WX-500 functions. Refer to your Aircraft Flight
Manual Supplement (AFMS) and the documentation supplied with
the MFD for detailed operating instructions. This chapter provides
supplemental information. The user should already be familiar with
their AFMS and MFD.
CONTINUOUS & OPERATOR-INITIATED SELF TEST
The WX-500 performs a continuous self test of antenna operation,
microprocessor functions, memory, and heading inputs among others
several times a minute. The WX-500 also provides for an operator-
initiated self test through the MFD.
