Symptom
$Nothing at all appears on the
monitor screen or the “NO SIGNAL”
or other warning display appears.Suggested remedial action
OFirst, check whether the monitor is a PC/AT compatible monitor.
OWhen nothing at all appears, check the supply voltage, connecting
cables (for disconnections) and monitor unit settings.
OSome monitors have their own self-diagnosis functions.  If you feel
that the monitor unit is responsible for the trouble, refer to the manual
accompanying the monitor, and check the adjustment and test
methods.
OIf you still cannot trace the cause of the problem, try replacing the
troubled monitor with a monitor whose operation is trouble-free if
such a monitor is at hand.
Troubleshooting Chart
Use the Troubleshooting Chart to remedy certain symptoms. Find the “Symptom” concerned in the left-hand
column of the table, and take the “Suggested remedial action” in the right-hand column.
Always make sure that you have conducted the basic checks before consulting the Table.
Symptoms related to personal computer monitor
$The display keeps running off the
monitor screen.OCheck the monitor’s resolution setting.
This product’s default resolution setting is 1152a
870, and its default
refresh rate setting is 75 Hz.
These settings may not display properly on some monitors.  Refer to
the manual accompanying the monitor, and check its available
resolution settings.
OIf you still cannot trace the cause of the problem, refer to the above
symptom (Nothing at all appears on the monitor screen or the “NO
SIGNAL” or other warning display appears), and check whether the
monitor is to blame for the problem.
Troubleshooting
$The display on the monitor screen
is subject to wave-like noise,
distortion or jitter resulting in
horizontal or vertical wobbling.OIf the monitor is determined by its self-diagnosis function to be
trouble-free, review the monitor’s installation location.
Trouble may be caused in the monitor display by the adverse affects
of magnetic fields generated by other devices (such as another
display, fluorescent light or   transformer). In a case like this, turn off
the monitor, distance the monitor from the other devices, and turn the
power back on. (The picture distortion, etc. may remain if the monitor
is moved while the power is still supplied.)

Symptom
$The floppy disk drive’s access lamp
remains lighted or the system fails
to recognize the floppy disk drive.Suggested remedial action
OHas the product been started up with a floppy disk already inserted in
the floppy disk drive?
When its power switch is set to the ON position, this product checks
whether a floppy disk has already been inserted in the floppy disk
drive, and it then starts the product.  If a floppy disk has not been
inserted, startup proceeds from the built-in system hard disk; if a disk
has been inserted, the product is started up from the floppy disk
drive.
For normal use, set the power switch to the ON position while there
is no floppy disk in the floppy disk drive: this will ensure that the
system starts up properly.
OCheck out the following points if this problem should occur while a
floppy disk has been inserted the floppy disk drive at times other than
startup.
1. Is the floppy disk damaged in any way?
(Check this using a trouble-free disk.)
2. Has the disk been inserted properly?
(Has it been inserted upside down?)
3. Does the editing application program lock up or does some other
software problem occur at the same time? Symptoms related to floppy disk drive

Symptom
$All or some of the keys on the
keyboard fail to function.Suggested remedial action
OAre you using the keyboard provided with the product?
Problems may occur in operation if a keyboard other than the one
provided with the product is used.
OHas the keyboard been connected?
OIs the keyboard connected to the mouse connector and is the mouse
connected to the keyboard connector?
Provided that both the mouse and the keyboard used are the ones
provided with the product, connecting them erroneously will not
damage the main unit but input operations will not be acknowledged
even if the connections are rectified while the power is still being
supplied.  In this case, the power must be turned off, the devices
must be connected properly and then the system must be re-booted.
Symptoms related to the keyboard or mouse
$Desired letters or numbers cannot
be input from the keyboard.ODoes the lighting of the [NumLock], [CapLock] and [ScrollLock] LEDs
reflect the desired status in each case?
The status of each of these LEDs is reversed every time the
corresponding key is pressed.  If you have not noticed that a key has
been pressed in error, what you input may not be as originally
desired.  Take [NumLock] for instance: the 10 number keys cannot
be used unless this LED is lighted.
$The mouse fails to operate
properly.OAre you using the mouse provided with the product?
Problems may occur in operation if a mouse other than the one
provided with the product is used.
OHas the mouse been connected.
OIs the keyboard connected to the mouse connector and is the mouse
connected to the keyboard connector?
For the suggested remedial action, refer to the above symptom (All
or some of the keys on the keyboard fail to function).
$The movements of the mouse
cursor are awkward.OAre you using the mouse provided with the product?
Problems may occur in operation if a mouse other than the one
provided with the product is used.
OIs the mouse roller or mouse pad dirty?
$The mouse cursor tends to
disappear or its display position
suddenly changes on its own.OAre you using the mouse provided with the product?
A mouse other than the one provided with the product may be more
susceptible to the effects of static or other types of noise.
Noise entering from the mouse or mouse connecting cable has the
effect of simulating mouse input and causing malfunctioning.
