Troubleshooting the Wireless Keyboard
The wireless keyboard is used in the same way as a normal
wired keyboard. In typical operation, you should encounter
few problems in transmitting data to your Tablet PC. If your
keyboard fails to perform properly, check for the following
circumstances:
The identification code has been changed inadvertently.
To correct this problem, first remove the batteries (see the
section of this chapter entitled "Replacing the Wireless
Keyboard Batteries"). While the batteries are out, tap any
key a few times. Reinsert the batteries. If this fails to solve
the problem, the batteries may need replacement.
The infrared transmitter on the keyboard is not properly
aligned with the Tablet PC infrared photosensor.
The keyboard is too far from the Tablet PC, or something
is obstructing the line-of-sight between the ports.
The remote control for another device (such as a television
or wireless headphones) is being operated in the same
vicinity as the keyboard.
The infrared transmitter on the keyboard and/or the
infrared photosensor on the Tablet PC are directly
exposed to sunlight or bright artificial light.
The infrared transmitter on the keyboard and/or the
infrared photosensor on the Tablet PC are dirty.
The keyboard batteries are dead (see the section below
entitled "Replacing the Keyboard Batteries").
