Infrared Data Transfer Is Not Working 3
If you are experiencing problems transferring data over the system’s infrared
interface, note the following:
• 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 not be more than approximately 3 feet
or 1 meter.
• 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.
• The device with which you are trying to communicate must be compliant with the
IrDA Standard Revision 1.1.
Pen Tablet Is Not Responding to the Pen 3
If your pen tablet is not responding to the pen, check the following:
• Ensure that the pen tip moves freely. Replace the pen tip if it is damaged or
warped. See “Replacing the Pen Tip” earlier in this chapter.
• Ensure that the pen battery is in good condition. Replace the pen battery if the age
or condition of the battery is suspect. See “Replacing the Pen Battery” earlier in
this chapter.
• If available, connect an external keyboard to the system to see if it responds to
keyboard commands. If the system doesn’t respond to the keyboard, the
application or system may have crashed, and it may be necessary to reset the
system.
Cursor Is Not Tracking Pen 3
If the cursor on the screen is not accurately tracking the pen or appears to be
misaligned with the pen, calibrate the pen. See “Calibrating the Pen” earlier in this
chapter for details.
