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.

4.4 Precautions

a) Use of video cards other than recommended A video card other than those recommended for use with CBdrvU must be calibrated from the Select Calibration Dialog (Detail-1). For information on recommended computers and video cards, consult a Pioneer dealer. b) Easy Setting Easy Setting is optimized for PDP-504CMX/PDP-50MXE1/PDP-50MXE1-S and Microsoft Windows XP. Cursor position may slip due to due to video card adjustment or characteristics, plasma display adjustment or discrepancies. Should this happen, perform calibration from the Select Calibration Dialog (Detail-1). Easy Setting cannot make settings at resolutions above 1024 x 768 and a vertical frequency of 60 Hz. Use Detail-1 from the Select Calibration Dialog to perform such settings. c) Driver The driver is optimized for the Pioneer handwriting device and pen. Some of the functions provided by this hardware combination may not be provided by other hardware combinations. DUAL displays are not supported. d) Initial plasma display settings The factory default for PDP-504CMX/PDP-50MXE1/PDP-50MXE1-S is XGA (SETUP = SIGNAL Format = XGA). Use the WXGA for Cyberboard. Note that some Easy Setting modes may differ when the XGA is used. e) Screen saver Some screen savers automatically change the resolution, for example, 3D Maze (OpenGL). Thus the system assumes the user has changed the resolution and displays a message prompting the user to calibrate the pen each time the screen saver starts. Should this happen, change to another screen saver or disable recognition of changes in resolution. f) Media player Some media players automatically change screen resolution in full screen mode and shows a message prompting pen calibration when leaving full screen mode. Should this happen, disable visual effect settings or recognition of changes in resolution. g) HTML optimization Some set values may interfere with normal operation, check before use. h) Pen operation in Welcome Login screen Pen position may shift in the login screen of Windows 2000 and Windows XP. Should this happen, use the mouse or keyboard for logging in. i) Portrait installation of plasma display Portrait installation is described on the assumption that it will be performed by a competent professional engineer with sufficient training and skill to carry out proper installation. Ask your dealer or other authorized personnel to perform installation. Pioneer cannot accept liability in cases where the equipment is damaged due to inappropriate installation location, improper assembly, installation, setup, operation, renovation, or by natural disasters.

c) To make observations of infrared LED light emitting status using a CCD camera This setting performs a slow scan in approximately 1 second cycles. (Locked ultra low scan mode) The light emitting status of infrared LEDs can be observed in a dark room, but this depends on the camera used. The touch panel input functions do not operate in this mode. The power indicator on the device front panel blinks continuously in approximately 1 second cycles.

7. Q & A

7.1 Hardware-Related Q&A
Q: Which is the touch panel system? A: It is based on the IR scan system. Q: Which is the advantage of the IR scan system? A: It is the capability of direct drawing on the screen. This does not deteriorate the picture quality nor cause parallax. Q: Are there any consumables? A: The pen tip and the battery are consumables. Two extra pen tips are supplied. The pen tip is available as a service part. Q: How long is the service life of infrared LEDs? A: 10,000 hours or more in a normal operating environment. This refers to hours of continuous use. Since normal use is not continuous, service life under normal conditions should be two or three times 10,000 hours. Q: How long is the service life of the pen battery? A: 20 hours of continuous use when an alkaline battery is used. One screenfull of characters that are 6 cm wide and 6 cm high would contain 120 characters (when two thirds of the screen is used for writing). It takes an average of 1 second to write a 6 cm wide and 6 cm high character, one screenfull takes 2 minutes to write. Assuming that 5 pages are written every hour of class or business meeting, the pen is used 10 minutes every hour. If there are 6 hours of classes or business meetings per day, the battery is used up to 20 hours, which would correspond to one working month (20 days). The pen battery should therefore last a month. Q: Does the system deteriorates by aging? A: Basically, it does not deteriorate over time. However, malfunctions may occur if the light intensity drops considerably due to excessive deposition of cigarette tars or dust. Q: Which are the effects of dirt on the performance? A: Dirt on the IR filter should be removed because it deteriorates the light intensity. Q: What would happen if the light sensor elements break down? A: To ensure normal operation, malfunctioning sensors are detected and removed from processing at the time the power is turned on. However, as the resolution may drop in the areas where malfunctioning sensors are detected, detailed drawing is not possible in those areas. Q: Which is the detection distance from the panel surface? A: The reaction to a light-shielding object is variable depending on the thickness and positioning of the object, but it is usually detected at about 5 mm from the panel surface. Q: Is it possible to write letters using an object other than the special pen? A: Yes, it is possible. In addition to the PEN mode, a mode is provided to allow writing by anything including a finger (NORMAL mode). The factory-setting mode is the NORMAL mode. Q: Writing on the screen using a finger will soil it. Can a glass cleaner or similar detergent be used to clean the screen? A: Basically, such detergents should not be used. Use the supplied wiping cloth to clean the plasma display. If the screen is heavily soiled and a detergent is required, use a soft cloth slightly dampened in a solution of a neutral detergent and water. Wring out the cloth thoroughly, wipe the screen clean and then wipe with a dry cloth. Q: Is the screen scratch resistant? A: No, bringing a propelling pencil or other sharp pointed object in contact with the screen will scratch it.

Q: Is there a convenient way for adjusting the plasma display monitor? A: With the PDP-504CMX/PDP-50MXE1/PDP-50MXE1-S, adjustments are possible using the AUTO SET UP MODE. CBdrvU ver.2.0 also provides a pop-up menu, in which you can output the test image signal by selecting Test Mode = Test Image. Q: Is calibration possible for resolution that is not specified by the VESA standard? A: Even when dealing with unknown calibration, CBdrvU is capable of performing the 4-point calibration and control the special pen. However, Easy Setting is not available in this case. When displaying a picture with other resolution than specified, be sure to confirm that the plasma display monitor is compatible with the resolution. Q: What is a good way of checking network settings? A: Use the CBdrvU ver. 2.0 pop-up menu to open the Test Mode and see if the IP address and name of the connected computer appear. For information on how to set the IP address and computer name, consult the PC administrator. Q: What to do if the position of the special pen tip is deviated? A: The condition of normal output to the plasma display monitor is set as the initial value, but it may be deviated slightly due to the difference in video card. If this happens, use the detailed calibration for setting. The set value is held in memory even after the next startup or resolution change. Q: Is it necessary to prepare a special development library when creating an application using the handwriting device? A: CBdrvU is a permanently resident type device driver. It is capable of converting the absolute coordinates on the handwriting device into the mouse coordinates by simply being started up. Therefore, an application can be created and run in the completely identical methods to general Windows applications. This means that no special tool like an API, DLL or SDK is necessary. For the method of creating applications, refer to the Help in your development tool.

Problems commonly mistaken as breakdown
Problem The screen is displayed in a small size. Letter breakup on screen. Possible Solution Is the correct screen size selected? Adjust using SCREEN mode on the menu screen. If there is still no improvement, this unit may be limiting the displayable range. Check the Computer signal compatibility table. Expansion/contraction caused by surrounding temperature change may result in sound being heard from the cabinet. This is not a malfunction. When the video input signals level is too high, the bright portions may appear to be losing their intensity. Increase the adjustment level of the contrast and check the picture. May be caused by radio wave interference from appliances with motors such as hair dryers, electric vacuum cleaners, electric power drills, ignition systems of cars, motorcycles etc., switch devises such as thermostats etc., neon signs or electrical discharge from power lines etc.
A sharp sound is sometimes heard from the cabinet. Bright portions of image appear to be losing intensity. Speckles or noise appears on screen.
Problem Stripes appear on the screen. Possible Solution May be caused by radio wave mingling from TV station, FM station, amateur radios, public radios (simplified radios) etc., or a nearby personal computer, TV, or video/ audio component. A strong electromagnetic field may cause picture distortion and similar problems. Normal sound of the cooling fan and internal sliding parts of the plasma display panel. Not a malfunction. Fan is set to operate only after ambient temperature exceeds 35C (differs depending on installation conditions). Not a malfunction. Fan speed changes automatically in accordance with ambient conditions. Not a malfunction. The ON indicator may not light in some cases, depending on the settings performed by the installer. Consult with your installation technician.
Sound is heard from inside the unit. Fan isnt moving. Fan speed changes. ON (green) indicator doesnt light.
About the self diagnosis mode

Vertical beam scanning direction
b) High scan mode After a light-shielding object is detected, scanning is concentrated in the area around the detection position in order to improve the response and positioning accuracy. In this mode, the IR sensors receive light from oblique directions as well as the light from the IR LEDs located opposite to them. As interpolation is applied based on the position information obtained in this way, the position information can be improved drastically in this mode. The High Scan area tracks the movement of the light-shielding object.
