Dimming
To adjust the light intensity the Dim button is pressed.
While the Dim button is pressed the intensity is changing. Releasing Dim will
maintain the current light intensity.
A renewed pressing of the Dim button will change the direction of light intensity change.
If the VHF is dimmed to zero, any key press will wake up the light to a minimum visible at
night. Active text in the information/message display might prevent dimming to zero.
It is possible to reduce illumination to zero. If you press a key in this state the light will
illuminate to the lowest illuminated state for 5 seconds, whereafter it will return to the zero
illumination state. If a message is shown on the screen while dimming was set to zero, the
illumination is adjusted to the lowest nonzero value.

Contrast
Contrast of the information/message display (and thereby optimizing the vertical viewing
angle) can be adjusted initially by entering Display Contrast menu. Use the arrows to adjust
contrast. The contrast will simultaneously be set during adjustment.
