7)
Max. 3000 m
1) Maintenance Controller Extended.
2) At max. specified ambient temperature: typ. 50 ppm (4 seconds) - worst-case 100 ppm (8 seconds).
3) Typical lifespan (at 50% buffer operation, tempe25°C when off, +50°C when on).
Maximum lifespan in 24-hour operation (no buffer) 6 years at +25°C or 5 years at +50°C.
Maximum lifespan switched off: 2 years at +25°C or 1 year at +50°C.
4) The actual value depends on the operating system or diver being used.
5) At +25°C ambient temperature. Reducing the brightness by 50% can result in an approximate 50% increase of the half-brightness
time.
6) Depending on the process or batch, there may be visible deviations in the color and surface structure.
7) Derating the maximum ambient temperature - typically 1°C per 1000 meters (from 500 meters above sea level).
