1. Defective Key
If the key is not producing any characters or the wrong character, the Keypad may be defective.
Please test the Keypad on another computer system and if it is still experiencing the same results, Please Email Support for further assistance.
2. Numlock on Keypad enables Function enabled 10-key on keyboard.
We designed our Keypad and Keyboards to function together, but only when connected with like connections, e.g., USB Keypad and Keyboard, or PS/2 keypad and Keyboard.
If the keypad and keyboard are connected using mismatched connection types, both the keyboard and keypad will function independently causing unwanted operation.
For best results, please match connections types when using both the Goldtouch Keypad and Goldtouch Keyboards.
3. PS/2 to USB adapter
Make sure the keyboard is connected directly to the computer systems PS/2 or USB port depending on which Keyboard model is being used.
We have seen some issues with using a PS/2 to USB adaptor. Please use a PS/2 to USB Converter as is not only changes the Plug type to fit the computer system, it includes smart Circuitry to convert the signals.
If you have ruled out the Converter and have tried all possible ports on the computer system, try connecting to a different type of computer to determine if the issue is the computer system or the keyboard.
We have received positive feedback from customers using the following Converter.

4. USB Ports
If you are connecting a USB numeric keypad in conjunction with a Goldtouch keyboard, be sure to connect it via your computer's USB. For correct operation, the numeric keypad must be plugged directly into the computer for installation, but can be connected through a hub once the drivers have been installed.
Do not attempt to plug the keyboard into one of the USB ports located on the sides of the USB keypad, as these ports are intended only for low power devices, like mice or USB storage drives. Doing so may cause the keyboard and keypad to malfunction.
