g) Temperature: -40 C to + 55 C
h) Altitude: 55,000 feet
i) Panel Lighting: 5 VDC or 28 VDC (PMR only)
j) Display Lighting: Light Emitting Diode (LED) Lighting (PMR only)
k) Contrast Ratio:
1. 650:1 Minimum, 900:1 Typical
2. (dark ambient contrast (PMR only) per ICDM/VESA Standards)
Backlight brightness in daylight mode:
1000l Cd/m² capable (depending on lighting curve) (PMR/RCDU only)
Backlight brightness in NVIS or Night mode:
34l Cd/m² capable (depending on lighting curve). (PMR/RCDU only)
Luminance levels are the same for NVIS or Night mode. NVIS mode changes
the chromaticity (color) to be compatible with NVG
