94 Troubleshooting the PenCentra 200
Infrared Data Transfer Is Not Working 6
If you are experiencing problems transferring data between Windows CE-based
devices, note the following:
• Transfer only one file, or no more than 25 contact cards at a time. For more
information on contact cards, reference the section of Chapter 3 entitled
“Contacts: Tracking Friends and Colleagues”.
• Can the IrDA port on the pen tablet “see” the IrDA port on the other device? A
direct line-of-sight path must exist between the IrDA port on the pen tablet and
the IrDA port on the other device.
• The distance between the two devices must be less than 3 feet (1 meter), but more
than two inches.
• The viewing angle from the IrDA port on the pen tablet must not be more than 15
degrees from a center line between the IrDA port on the pen tablet and the IrDA
port on the other device.
• Adjust the room lighting. Some types of light interfere with infrared
communication (including direct sunlight). Try moving to a different location or
turning off some lights.
Pen Tablet Is Not Responding to the Pen 6
If your pen tablet is not responding to the pen, check the following:
Note: A quick way to tell if the pen is responding is to try to adjust the volume hotpad.
You will hear a beep if it is working properly. This will help determine if the system
is not responding or if the application is locked up.
• Ensure that the pen tip is clean. Replace the pen if it is damaged.
• If available, connect a USB-style mouse to the system to see if it responds to click
commands. If the system doesn’t respond to the mouse, the application or system
may have crashed, and it may be necessary to reset the system.
Pen Tablet is Not Responding to the Keyboard 6
If the pen tablet is not responding to the keyboard, check the following:
• Make sure that you suspend and then resume the system before attempting to use
the keyboard, otherwise it may not be recognized.
• Be sure that you are using a 5V keyboard.
