Fife H3257
MI 1-921 1
Adjusting the light
intensity
The H3257 must be powered on to change the intensity. The
device will retain the selected intensity level between power
cycles.
Adjustment button
Adjust the intensity level with a small pushbutton located
behind a hole plug on the front panel.
-
Gently pry out the hole plug.
-
Use a small, non-conductive tool to actuate the button.
-
Each press of the button increases the intensity level by
10% of the maximum.
-
Once the maximum intensity has been reached, the
intensity will revert to Setting 1 on the next button press.
LED bar graph
Next to the pushbutton is an 8-LED green bar graph.
Each lit LED in the bar graph represents one intensity level.
This H3257 is set at intensity level 4.
Dual light source only
This H3257 is operating as the slave.
In dual configuration, both light sources use the same
intensity, which is controlled and displayed on the master
light source.
