Operation Manual
On-screen keyboard
On-screen keyboards are available on almost all computers and tablets. However, they are used in touch screen devices such as tablets and
all-in-one computers. You can select the keys using a mouse or by touching the keys on a touch screen.
Keyboard connection types
Keyboards can be connected to your computer with a cable (wired) or using wireless signals (wireless).
Wired
Wired keyboards are connected to the computer using a cable (generally USB) and do not require additional power source, such as
batteries.
Wired
Wireless keyboards use Radio Frequency (RF) or Bluetooth (BT) to connect to your computer. Cable clutter is reduced and gives you the
exibility to use the keyboard from a more comfortable position within a few meters from the computer. Such keyboards require batteries
to operate.
A keyboard that uses RF technology usually ships with a receiver that you must connect to your computer. Bluetooth keyboards can pair
with your computer’s built-in Bluetooth card or an external Bluetooth adapter.
