1.4.2 Handwriting device (PDK-50HW3)
a) Scan device
Power indicator
(Lights green when ON)
IR transmitting filter
PEN
NORMAL
Rear side
of unit
When the power switch is first turned on, the power
indicator will flash orange; while the indicator is
flashing, do not touch the screen, since the unit is
initializing its internal settings
Mode selector switch
Set the mode switch in accordance with
whether you will use the special pen or
other device to input characters and lines
on the screen.
PEN Mode:
In this mode, the
special accessory
pen can be used to write on the screen.
Using the special pen allows the drawing
of more clearly delineated characters and
lines.
NORMAL Mode:
In this mode, your
finger or other
object can be used to write on the screen.
This mode will produce lower screen
definition, however, compared to drawing
with the dedicated input pen.

If pen operation becomes difficult:
The pen may fail to operate properly if the holes in rear
end of pen are blocked. Also, the pen may begin
operating erratically when the battery becomes depleted.
In this event, change the battery at your earliest
opportunity.
Confirming Battery Life:
When the small button is depressed fully, an LED
indicator will light. If the indicator fails to light, or lights
only dimly, the battery is depleted and should be
replaced.

2. Installation Site
2.1 Installation Site
The installation site precautions for the handwriting device are the same as those for the PDP-504CMX/PDP-50MXE1/
PDP-50MXE1-S. For details, refer to “Installation Site Requirements” in the Technical Manual of the PDP-504CMX/PDP-
50MXE1/PDP-50MXE1-S.
2.2 Installation Conditions
For information on calculation of heat generation and heat dissipation, installation site and installation on uneven
surfaces, refer to “Installation Conditions” in the Technical Manual of the plasma display.
2.2.1 List showing compatibility of standard metal fittings
Not possible since the handwriting device will be in
contact with the base.
Installation is physically possible, but not recommended
since the table top may not be sturdy enough to offer
good support during pen input.
Possible.
Possible. Difficult for wall mounting.
Possible.
Installation is physically possible, but not recommended
since the table top may not be too unstable to offer good
support during pen input.
Possible. Recommended standard product.
The handwriting device, if installed, blocks access for
speaker installation brackets.

2.2.2 Special installations
Special installation conditions for the handwriting device are the same as for the plasma display. Refer to “Special
Installation” in the Technical Manual of the plasma display.
¶ Calculate the distance between the monitor and surroundings (wall, etc.) based on the maximum dimensions of the
scan device.
¶ The handwriting device can be tilted in the range between horizontal, upward-facing position and the 25° downward-
facing position. The following cautions are required in its installation.
Facing upward
¶ When the handwriting device is installed horizontally so that it faces upward, the user may tend to rest a hand on or
lean against the handwriting device frame. As imposing a weight on the frame may deform it, cause malfunction or
damage it, it is required to prevent it using a guard, etc. If you install a guard, however, you need to take ventilation of
the plasma display monitor in consideration.
¶ When the handwriting device is tilted, the user should watch the screen obliquely and, in this case, the position of the
pen tip and that of the displayed pointer may look deviated. Note that the calibration in the detailed setting mode of
the driver cannot be adjusted correctly unless it is performed from the actual direction of the user’s view. The
adjustment may sometimes be easier when it is performed in simplified setting rather than in the detailed setting
mode.
¶ When the handwriting device is installed horizontally so that it faces upward, the risk of causing damage or
malfunction by dropping a foreign object on the screen increases. The foreign object may for example include a liquid
(juice, coffee, detergent, etc.) spilt on it, the hem of the user’s necktie or shirt in contact with it, and dust that may
cause sensor malfunction. Also, someone may use the horizontal screen in place of a table. Always take their
prevention in consideration when installing the handwriting device horizontally.

2.2.3 Installation precautions
a) Installation of multiple systems
Since the dedicated handwriting pen of the system is designed to function as a switch by emitting ultrasound waves,
mutual interference may occur when more than one system is installed in proximity (the interference may also be
observed even when the areas are separated with a simple tool such as partitions). In this case, it is required to use the
systems in NORMAL mode.
Some of the installation examples in which mutual interference is expected are shown below.
¶ Adjacent installation
¶ Adjacent booths delimited with simple partitions
¶ Back-to-back installation across a simple partition
b) Exposure to direct sunlight
Normal lighting is not a problem, but installation in a location exposed to strong lighting and intense direct sunlight will
make the plasma display difficult to view and make toucth screen device operation unstable. Installation in such a
location will also make remote control operation erratic.
Note that whereas normal fluorescent lighting does not emit infrared radiation, incandescent lamps emit a large amount
of infrared radiation. When the system malfunctions due to the presence of strong lighting, move the light source away
or change its orientation to prevent malfunction. Also, when equipment generating IR rays (electric stove, IR LAN, etc.)
is located near the handwriting device, its operation is usually normal but may sometimes be rendered unstable under
certain installation conditions. This needs to be checked in individual installations.
c) Ultrasonic waves
When equipment using ultrasonic waves (ultrasonic humidifier, ultrasonic-sensor door, ultrasonic eyeglass cleaner, etc.)
is used near the handwriting device, its operation is usually normal but may be rendered unstable under certain
installation conditions. This needs to be checked in individual installations.
