Targus Wireless Calculator Keypad
Troubleshooting
What do I do if the keypad does not work?
• Make sure that the polarity of the batteries is correct. The
positive (+) and negative (-) ends of each battery must
match the positive (+) and negative (-) connections in the
battery housing.
• Check that the receiver’s USB connector is firmly
attached to the USB port on your computer.
• Verify that the device drivers are installed.
• Make sure you have established a communication link.
See “Establishing a Communications Link” on page 5.
When I use the calculator/keypad, other wireless
devices work more slowly or fail temporarily – what
should I do?
• The calculator/keypad may cause interference with any
cordless, radio-based device that operates at 27 MHz,
such as a telephone, baby monitor, or toy. To reduce
interference, move the calculator/keypad’s receiver and
the base unit of the affected device as far away from each
other as possible.
• You can also reset the calculator/keypad’s identification
code. To do this, see “Establishing a Communications
Link” on page 5.
