The EFIS control panel controls the radio minimums value and resets the radio minimums alert display to a normal display. The radio minimums shows on the captain and first officer display units. The left EFIS control panel controls the captain display units. The right EFIS control panel controls the first officer display units.
The minimums controls have these three controls:
· A two-position rotary switch (minimums reference selector)
· A spring loaded rotary switch (minimums altitude selector)
· A radio minimums reset (RST) switch.
You use the radio position on the minimums reference selector to set the radio minimums.
To set a radio minimums value, use the rotary switch to adjust the value between -1 feet and +999 feet.
Push the radio minimums reset (RST) switch to set the radio minimums alert display back to normal.
