is
noted, check all of the areas mentioned, starting from the top of the
menu.)

If
the nature of the problem isn't indicated, select the system test.
Note: Four disc-based tests require special preparations:
The
HP-IL
test requires either
that
you connect a good HP-IL cable between the IN
and
OUT
receptacles or that you connect the computer
and
one
or more devices
in
a loop.
The
RS-232-C
(serial
interface)
test requires you to connect the RS-232-C test connector to
the
serial port.
The
modem
test includes "dial"
and
"ring" options that require two
phone
lines to
be
connected
to the modem port.
The
system test performs the three tests listed above
and
requires the preparations for each
of
them.
