before you switch the device off. This allows the drive to come to a
complete stop and ensures optimal protection.
3. Unplug all the connecting cables.
4. Close the covers protecting the ports and connections on the right-hand
and left-hand side panels.
5. Bring the unit into an upright position.
6. Raise the keyboard and lock it by pressing it against the front panel of the
unit. The latches on the right and left snap in. Make sure that both catches
are properly locked.
7. If you only want to carry the unit for a short distance, use the handle.

The display of the PG 720 is an STN color display with a diagonal of 10.4 in.
(26 cm) and a resolution of 800 x 600 pixels.
The three primary colors, red, green and blue, can each be displayed in eight
different shades. This means that, including all the secondary colors, a
maximum of 256 different colors can be displayed. The contrast can be
adjusted with a control to the left of the display.

Note
Depending on the gray tone or color shade in the display, passive STN
displays are subject to varying degrees of interference known as the Moiré
effect. This is a physical characteristic and is not a fault.
Caution
!
Risk of injury!
If a display is damaged, liquid crystals may escape. Do not touch this liquid
or allow it to come into contact with your skin in any way, and do not breath
in the vapors. If you do come into contact with the liquid, wash those parts
of the skin affected immediately with alcohol, and rinse with plenty of water.
Then consult a physician immediately.
Use only a cotton cloth and a neutral cleansing agent to clean the display. Do
not use water or aggressive solvents (such as alcohol or acetone). Never
touch the display with hard, sharp objects. Avoid exerting any pressure on
the display surface.

Trackball
Cleaning the
Trackball
The trackball is a pointing device for cursor control and menu selection in
many programs that support mouse operation. By moving the trackball, the
cursor can be positioned anywhere on the screen.
By pressing the left-hand button, you set a marker. The function of the
right-hand button depends on the particular program you are using. You can
select objects or items in a menu and start functions with the trackball.
The trackball is in a roller housing which normally prevents dust collecting
on the ball or transmission mechanism. Nevertheless, you should clean the
trackball at regular intervals.
T o clean the trackball, proceed as follows:
1. Switch off your programming device.
2. Remove the cover of the trackball housing by turning it anti-clockwise,
for example by inserting tweezers or a similar tool into the holes in the
ring.
3. You can now take the trackball out of its housing.
4. Wash the trackball in a solution of tap water and mild cleansing agent.
5. Blow any residual dust out of the trackball housing.
6. Dry the trackball and return it to its housing.
7. Replace the cover and tighten it by turning it in a clockwise direction.

Hard Disk Drive
!
CD-ROM Drive
You can use a number of different hard disk drives in your PG 720. The memory
capacity of the particular type of hard disk can be found in the Product
Information Bulletin and SETUP program.
Whenever the hard disk drive is accessed, the access LED on the front of the unit
lights up.
Caution
Risk of data loss and damage to drive!
Drives are sensitive to vibrations and shock. Any vibrations occurring during
operation can lead to the loss of data or damage to the drive.
After the operating system has been shut down, wait approximately 5
seconds before switching the device off. This allows the disk to come to a
complete stop and ensures optimal protection.
If you intend transporting the unit, switch it off, and wait until the drive has
come to rest (about 20 seconds) before you move it.
The CD-ROM drive enables you to read CDs. The drive is operated as a slave
parallel to the hard disk drive via the secondary IDE interface.
Self-T est
Caution
!
Risk of data loss and damage to the drive!
CD-ROM drives are sensitive to vibrations and shock. Any vibrations occuring
during operation can lead to damage to the drive or CD.
Whenever the PG 720 is switched on or reset, the hard disk drive runs
through a self-test which is repeated during operation.
