If your SM3 Slim Mechanical Keyboard (ST-BTSMKW3) doesn't appear in the Bluetooth device list on your Mac, iPad, or iPhone, it may not be in pairing mode or may already be connected to another device.

Try the following:

1. Press and hold Fn + 1, Fn + 2, or Fn + 3 (depending on the Bluetooth channel you want to use) for about 3 seconds until the pairing LED begins flashing.
2. Open your device's Bluetooth settings and look for Satechi SM3 in the list of available devices.
3. If the keyboard was previously paired with your device, remove ("Forget") it from Bluetooth settings before pairing again.
4. Make sure the keyboard isn't currently connected to another device on a different Bluetooth channel.
5. If needed, switch to another Bluetooth channel by holding Fn + a different number key (1, 2, or 3).

If the pairing LED does not flash when entering pairing mode, please contact Customer Support for warranty assistance.
