during which “no change of Aperture setting” is detected, the “set illumination level” is
retained.
During this illumination setting process, I lens operations continue to function
normally.
To alter the brightness of one set of LEDs, move the Aperture ring to the aperture
setting T1.4 end-stop and move it away towards T22, then repeat that process twice
more within 0.5 second.
This will cause the LED’s to be set to OFF for 0.3 sec, then ON for 0.3 sec, then OFF
again. The operator can now adjust the desired level by moving the Aperture scale up
(towards T22) or down (towards T 1.4). If there is a half second period during which “no
change of Aperture setting” is detected, the “set illumination level” is retained.
During this illumination setting process, I lens operations continue to function
normally.
To turn off LEDs, move the Aperture ring to the aperture setting T1.4 end-stop and
move it away towards T22, then repeat that process twice more within 0.5 second.
This will cause the LED’s to be set to OFF for 0.3 secs, then ON for 0.3 secs, then OFF
again. The operator can now wait a half second and the “off-set illumination level” is
retained.
