time to changes in ambient light. A
setting of 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. The
factory setting is 1.
Display Adjust 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 at night. The factory setting is
20.
Display Adjust 3 (dA 3) varies the
amount of ambient light required for
the display to reach its full dim and
bright levels. A common use of dA 3
is to adjust the KT 70 and KT 71
display brightness to match the
brightness of other radios’ displays
and to provide display brightness
compensation as the display ages.
The factory setting is 0.
The following steps allow you to
access these adjustments:
1. Turn the Function Selector Knob
to TST.
2. Press and hold the IDT button for
five seconds, until “dA 1” appears
in the altitude window.
3. Select the desired display
adjustment (dA 1, dA 2, dA 3) by
pressing the VFR pushbutton.

in the IDENT window, using the

dA 3 (Vendor/Age
compensation):

5. Press the IDT pushbutton or turn
the Function Selector Knob to

saving the new values.
