The frequency selector knobs are
used to change the value in the
“STBY” window. Momentarily pressing
the channel button steps the unit
through the Display Adjust Modes,
“dA 1” through “dA 3”. Press the
frequency transfer button to exit the
Display Adjust Mode.
Display Adjust 1 (dA 1) is used to
vary the dim/bright response time to
changes in ambient light on the
display photocell. The range of values
for dA 1 is 1-8, with 1 representing
normal.
The normal setting, 1, provides
immediate display brightness changes
when there are changes in the light
falling on the photocell. With dA 1 set
to a value of 8, the response time is
approximately eight seconds. dA 1
values of 2 through 7 provide
intermediate response times.
Display adjustment 2 (dA 2) is
used to vary the display brightness
when ambient light conditions are less
than direct sunlight, such as in a dark
cockpit. dA 2 values range from 0-64,
with 0 being dimmest and 64 being
brightest; the normal dA 2 setting is
20.
dA 3 values range from 0 to 255,
with 0 being dimmest and 255 being
brightest. This adjustment varies the
amount of ambient light required for
the display to reach its full dim and
bright levels. Normal dA 3 values for a
new display range from 0 to 30.
A common use of dA 3 is to
adjust the KY 196A, KY 197A or KY
196B display brightness to match the
brightness of other radios’ displays.
Another use is to provide display
brightness compensation as the
display ages.
