If failure is detected in an area other than the mainboard (such as the
keyboard or an adapter card), an error message is displayed on the screen
and testing is stopped.
If your system does not successfully complete the POST, but displays a
blank screen, emits a series of beeps, or displays an error code, consult
your dealer.

A few common hardware problems and suggested solutions are presented
in the table below:
Problem Solution
The display screen is dark. Adjust the screen brightness. (Refer to
the monitor user’s manual).
Make sure that the POS Terminal is
not in Suspend mode.
An incorrect date and time are
displayed. Correct the date and time using the
DOS DATE and TIME commands or
the options in the Setup Utility. (You
can also set the date and time in
Windows by double clicking the clock
on the task bar or in the control panel.)
If the date and time become incorrect
after a short time, your CMOS battery
may be depleted. Contact your dealer
to change the battery.
The message:
“Invalid system disk,
Replace the disk, and then press
any key”
appears during boot.
Check and make sure that you do not
have a non-bootable floppy diskette
inserted in your floppy drive. If your
FDD is empty, you may not have an
operating system installed on your
drive. Contact your dealer for support.
You hear irregular beeps during
operation of the POS Terminal and the
system halts. The problem is beyond the scope of
this manual. Contact your dealer for
support.
