off just a fraction when you try to make
the connection, you’ll damage pins.
Then you get arcing and a burned-up
connector.
Mating a transmitter to a floating
base plate still takes care. When you
remove or install the transmitter make
sure you go straight and slow!
Line up the guide pins and the case
locating pins. Slide the case in
easy until you feel the pins mate.
Then seat the transmitter. Don’t
force it! If it resists, you’re not
lined up.
Don't tighten

base plate on the T-983 transmitter is
supposed to float.
But some of you mechanics don’t
seem to believe it. You’re cranking
down the two attachment screws and
making the plate stationary.
When that happens, the flexibility to
mate the connector is gone. If you’re
our unit’s aviation vibration ana-
lyzer (AVA) is infected with the Year
2000 (Y2K) bug—meaning the AVA
will shut down on 1 Jan 00 unless you
take action to prevent it. Change 4 to
TM 1-6625-724-13&P (Aug 94) tells
you how to keep it working.
You need to change the current year
(99) to the conversion year (91) before
1 Jan 00. Here’s what you do:
Turn on the AVA Control and Dis-
play Unit (CADU).
Select MANAGER by pressing the
F4 function key.
Using the directional arrow buttons,
highlight SETUP on the next screen
and press the DO button.
Highlight SET TIME & DATE and
press the DO button.
Enter the conversion year (91) in
place of the current year (99) and press
the DO button to save and exit.
If you don’t change the current year
to the conversion year before 1 Jan 00,
you will need to REFORMAT your
CADU. Assistance is available by con-
tacting Robert Branhof at (256) 313-
4948 or DSN 897-4948 or by e-mail
at:

This work-around holds the Y2K bug
at bay until a permanent fix can be
fielded.
Change 4 also changes the AVA cali-
bration requirement from once every
360 days to once every three years.
