Intensity

operational range of the lantern.
writes the range in nautical miles (0–9) where x represents the range
writes the range in nautical miles (0–32) where x represents the range
A range value from 13 to 21NM is valid however the maximum allowable range is dependent on the
lantern’s vertical divergence, LED colour and flash character.
Using the selected operational range and current flash character, the lantern uses the Schmidt-Clausen
Method, as described in IALA E200-4 to determine the peak intensity.
If the flash character is changed, the peak intensity is automatically adjusted.
