1 WX (WEATHER)
The WX button is used to select the weather mode of operation. When
WX is pushed, the system is fully operational and all internal
parameters are set for enroute weather detection.
Alphanumerics are white, and WX is displayed in the mode field.
If WX is selected prior to the expiration of the initial RTA warm up period,
the white WAIT legend is displayed in the mode field. In wait mode, the
transmitter and antenna scan is inhibited and the memory is erased.
Upon completion of the warmup period, the system automatically
switches to WX mode.
WX can only be selected when the function switch is in the ON position.
