Troubleshooting
Overview
This is a chapter we really
didn't
enjoy
writing
because it means that
you're
having trouble with
your
PK-
96
and that
you're
not on the air. This
chapter is by no means all-inclusive
of everything that could cause
problems,
but it is
a
guide
to help
you
solve
the
most
common
problems
that occur.
Although
the
PK-96
is a
complex
piece
of equipment, we've found
that
most
troubleshooting
problems
are
directly attributable
to five simple sources:
.
Insufficient power
supply.
.
Incorect
or improperly wired connections.
.
trncorrect
tuning
procedure.
.
Unfamiliarity with
the commands.
.
Sofiwareincongruitics.
Because there
are scores of diff'erent software and hardware
configurations available to use with the PK-96,
it's
impossible
to list all the solutions
to the software/hardware-related
problems
you
may encounter.
Be-
Ibre you
pull
your
hair
out and call us in frustration,
do
what
electronic technicians
do: relax, do some-
thing
else to clear
your
head, re-approach
the
problem,
and try to think it through logically.
A Troubleshooting
Primer
The
whole trick to troubleshooting
is
playing
detective:
your
job
is to determine
the cause of the
problem
by eliminating what
can-or can't-be the
culprit.
By
using
your
head
and a
VOM
(multimeter),
you'll
succeed
99Vo of the time.
The
first step is to
break down the main
components in
your
system into subsystems. They
are dia-
grammed
in the following figure
on the next
page.
