Double USB hub
A double USB hub is integrated in the Calculator
Keypad. This allows you to connect other USB
devices using Plug&Play technology.
This means that you do not have to restart your
laptop or PC every time and can immediately use
the USB devices connected.
Troubleshooting
When you turn on the keypad, if the keypad’s
LCD shows abnormal or nothing, check your
battery first. If the battery is working fine, try to
find an acicular metal and plug into the reset
hole (in the back of the keypad). Then the keypad
will work normally. If the problem was still
unsolved, please contact the technical support.
