Troubleshooting
The keyboard and/or mouse is/are not detected or do not work
after installation.
• Make sure the receiver cables are plugged into the PS/2 mouse port
and PS/2 keyboard port. Do not unplug or plug-in the receiver
cable while the computer is on.
• For optimal performance, place the receiver at least eight inches
(20 centimeters) away from the computer monitor, the computer,
any external storage devices, or other electrical devices.
• Make sure you have properly installed the batteries. Check to make
sure the batteries you have installed are not dead (you can do this
by installing them into another device).
• You may have other system devices that are conflicting with the
mouse and/or the keyboard. Check the IRQ/address settings of
these devices for conflicts and change the settings as required.
Refer to your computer documentation to make these changes.
• Make sure you have properly established
communication/synchronization between the receiver and the
mouse and keyboard.
• If the keyboard and/or mouse are not working, make sure that the
LED on the keyboard and/or the mouse start flashing when you
push any of the keyboard keys, mouse buttons, or move the mouse.
If the LED does not flash, check to make sure you have installed
the batteries correctly.
• When the keyboard or mouse LEDs are flashing, the LED on the
receiver should also flash to indicate they are speaking to each
other. If the LED on the receiver does not flash, it means that the
devices have not connected properly. Push the reset button on the
receiver. Within five seconds, push the reset buttons on the mouse
and on the keyboard. Refer to Fig. 1, Fig. 2, and Fig. 3 in the
Hardware Installation section.
The mouse pointer becomes choppy on-screen or the keyboard
does not register keystrokes.
• Remove batteries and replace with a fresh set.
