• Take several short breaks, with stretching exercises if necessary.
• Change your posture often.

2. Switching the Keyboard On/Off

The keyboard switches to a low-power sleep mode after 30 seconds of inactivity. It reactivates automatically upon the first key press. For longer periods of non-use or for transport, manually switch the keyboard off using the switch on the back (Off = O, On = I).

3. Connecting the Keyboard to a Device

Connect the keyboard via USB cable, Bluetooth, or a 2.4 GHz wireless connection using the receiver. Bluetooth allows connection to up to 3 devices and switching between them.
