Function Keys (F-keys)
The F-keys (F1-F12) on the K750 keyboard have dual functions. By default, they perform media control and other quick actions. To use their standard F-key function, press the 'Fn' key (located near the left Ctrl key) simultaneously with the desired F-key.
Solar Power Indicator
Press the dedicated 'Solar' button (usually F11 or a sun icon) to check the keyboard's battery status. A green light indicates sufficient charge, while a red light suggests the keyboard needs more light exposure to charge.
Maintenance
To ensure optimal performance and charging efficiency, keep the solar panels located at the top of the keyboard clean. Use a soft, lint-free cloth (like the one provided in the packaging) to gently wipe away dust or smudges. Avoid using abrasive cleaners or harsh chemicals.
Troubleshooting
- Keyboard Not Responding: Ensure the keyboard is turned 'ON' and the Unifying receiver is securely plugged into a working USB port. Try plugging the receiver into a different USB port.
- Low Battery Indication: If the solar indicator light is red, place the keyboard in a brighter area for several hours to charge. The keyboard can charge from any light source, including desk lamps.
- Connectivity Issues: If the keyboard loses connection, try re-pairing it with the Unifying receiver using the Logitech Unifying Software (available for download from Logitech's website).
- Keys Not Registering / Typing Errors: Ensure the keyboard surface and keys are clean. For persistent issues, try restarting your computer.
- No Caps Lock/Num Lock Indicator Lights: The K750 does not have physical indicator lights for Caps Lock or Num Lock to conserve power. Logitech offers SetPoint software with an on-screen indicator for Windows users.
