- Ensure the keyboard is charged and powered on.
- Activate Bluetooth on your host device (computer, tablet, smartphone).
- Put the keyboard into pairing mode by pressing and holding the Bluetooth channel key (e.g., Fn + 1, 2, 3, or 4) until the indicator light flashes.
- Select 'Satechi SM1' from your device's Bluetooth discovery list.
- Repeat for up to four different devices, switching between them using the Fn + Bluetooth channel key.
3. Connecting via USB Receiver

- Insert the USB-A receiver into an available USB port on your computer.
- The keyboard should automatically connect without additional drivers.

- Connect the other end to an available USB-C port on your computer.

5. Operating System Compatibility
The keyboard is compatible with both macOS and Windows operating systems. It includes interchangeable keycaps for Windows shortcut keys.

Operating Instructions
1. Backlight Control
The keyboard features 14 levels of backlighting. Use the dedicated backlight control keys (typically Fn + F5 for dimming and Fn + F6 for brightening, or similar keys with sun icons) to adjust brightness or turn the backlight on/off. The backlight will automatically turn off when the battery is low to conserve power.
2. Battery Management
With backlighting enabled, the keyboard's battery provides up to 16.5 hours of continuous use. Without backlighting, the battery can last up to two months between charges. To conserve power, the keyboard enters sleep mode after 30 minutes of inactivity. Press any key to wake it up.
3. Adjustable Feet
The keyboard features adjustable feet on its underside. Extend or retract them to find your preferred typing angle. Adjusting the keyboard height can help reduce wrist strain and improve ergonomic comfort during extended use.
4. Keycap Removal
The keycaps are designed to be removable for cleaning or customization. To remove a keycap, gently pull it upwards with a keycap puller or your fingers. Exercise caution to avoid damaging the mechanical switch underneath. When replacing, align the keycap with the switch stem and press down gently until it clicks into place.
Maintenance
1. Cleaning
To clean the keyboard, first disconnect it from all devices. Use a soft, dry, lint-free cloth to wipe the surface. For deeper cleaning, remove the keycaps and use compressed air to clear debris and dust from between the switches. Avoid spraying liquid cleaners directly onto the switches or circuit board.
2. Keycap Care
When handling keycaps, apply gentle, even pressure. Avoid using excessive force during removal or replacement to prevent damage to the keycaps or the mechanical switches. Store any spare or removed keycaps in a safe, clean place.

Troubleshooting
- Keyboard Not Connecting:
Ensure the keyboard is sufficiently charged. Verify Bluetooth is enabled on your device and the keyboard is in pairing mode. If using the USB receiver, try a different USB port. Restart both the keyboard and your host device. - Backlight Not Working:
Check the battery level; the backlight automatically turns off when the battery is low. Ensure the backlight is not turned off or set to the lowest brightness level via the control keys. - Keys Not Responding:
Confirm the keyboard is properly connected via Bluetooth, USB receiver, or wired USB-C. Clean under the affected keycap for any debris that might be obstructing the switch. Ensure the keyboard is not in sleep mode. - Intermittent Connection:
Move the keyboard closer to your host device to improve signal strength. Reduce interference from other wireless devices operating on similar frequencies.
