SHIPPING INFORMATION
In
an extreme
case where
you
are unable
to
resolve
a
difficulty,
you
may want to take
your
Video Terminal
to
your
local Heathkit
Service
Center or ship it
to the
Heath
Company.
If you
can isolate
the
problem
to a
particular
circuit
board,
take
(or
send)
only
that
circuit board
for repair.
This
will save
shipping cost and
service expense.
Whenever
possible,
take
your
Video
Terminal
(or
cir-
cuit board)
to
your
local Heathkit
Electronic
Center
for
service.
Consult
your
Heathkit
Catalog for
the
lo-
cations
of the Electronic
Centers.

if it becomes necessary to
ship the complete
unit
to the Heath
Company,
do it as follows:
7. Remove
the cabinet shell. Do not

(the
