14. Troubleshooting
If the keyboard is not working as expected, try one of the following procedures to
correct the problem.
14.3.1. The keyboard does not type and is connected using a USB cable
1. Check the keyboard power light to ensure the keyboard is turned on. If the
power light is not on, press the power button to turn the keyboard on.
2. Check the pause light to see if the keyboard has been paused. If pause light is
flashing, hold
fn
and touch
esc
to unpause the keyboard.
3. Try changing the sensitivity level of the keyboard to its highest level (level 5).
4. Check the USB cable to make sure it is properly connected to both the
keyboard and the computer.
5. Check the operating system’s USB device table (for example, Device Manager
for Windows) to make sure the keyboard is enumerated properly as an HID.
Refer to the operating system user manual or help file for information about
how to check the HID.
6. Windows, and some other operating systems, may cache the USB Descriptor
tables and it is possible for these tables to get corrupted. If this happens,
remove the Cleankeys entry from the table and restart the computer.

properly as an HID device. Refer to your operating system user manual or help
file for information about how to check the HID.

flashing, hold
