Trouble shooting
If you have questions about installing or operating your Kinesis keyboard, first review the
relevant sections of this User’s Manual. If you are unable to solve the problem, visit the
Kinesis web site (www.kinesis.com). If you are still unable to solve the problem, contact
Kinesis technical support as described below.
Keyboard does not operate
If the keyboard has worked previously on the same computer and no changes or additions
have been made to the system, you can rule out a compatibility problem. USB devices are
designed to attach and detach while the computer is running and it is useful for diagnosing
problems to take advantage of this feature.
If possible, test another USB keyboard in the same USB port to be sure the computer and its
USB port are working properly. Watch when you attach the Advantage keyboard whether any
LEDs turn on, and whether a message appears on your computer. Does the Keypad function
key beep or turn on the far right LED? Do the keys generate their electronic "click?"
If no lights, Keypad beep, or clicks occur, the keyboard is not getting power. The most likely
cause is a defective main cable. If you want to try your own repair, contact Kinesis Technical
Support and ask if they will send you a replacement cable.
If the Keypad light comes on when the Keypad function key is tapped, but the capslock key
does not toggle the Capslock LED, then the keyboard is getting power but is not
communicating with the computer. The problem could be a damaged main cable or keyboard
microcontroller chip, or the computer may just be locked up. Try replugging the keyboard
and/or rebooting the computer before contacting Technical Support.
If the computer beeps repeatedly or the LEDs flash continuously when the keyboard is
plugged in, the microcontroller chip may have been damaged by static electricity. If you want
to try your own repair, contact Kinesis Technical Support and ask if they will send you a
replacement microcontroller chip.
A row or column of keys doesn't operate
This usually is caused by a loose connector between the keywell and the main (central) circuit
board. If thumb keys are included, it may indicate a broken ribbon cable which connects the
thumb keys to the main circuit board. Contact Technical Support with your serial number to
determine whether a replacement part is available.
