HAZARD DISPLAY SUPPRESSION

If the Hazard Display Configuration of the radar system is installed, it
may occasionally be desirable to suppress the display of Turbulence,
Hail Icons, and Lightning Icons in order to view the underlying reflectivity
levels.
Use the following procedure to suppress the display of the Hazard
Indications:
In AUTO or MAN mode, rotate the GAIN knob out of the CAL position
•
and then back to CAL to suppress the hazard icons and turbulence
indications for approximately 15 seconds.
If you use the GAIN knob to go to variable gain (VAR), the hazard
•
icons and turbulence indications will be suppressed for about
15 seconds after the last adjustment of the GAIN knob, and then
restored.
If you are already in variable gain (VAR) and wish to temporarily
•
suppress the display of the hazard indications, simply turn the GAIN
knob to CAL, and then back to the desired gain setting.
If you switch to the AUTO or MAN mode while using a variable gain
•
setting (VAR), the hazard icons and turbulence indications will be
suppressed for approximately the first 15 seconds after entry into the
new mode, and then restored.
The display of REACT and PWS Icons is not affected.
•
Note that prolonged use of VAR gain is not recommended.
