Modes of connection

Wired Mode

When the mode switch is in the “OFF” position, the mouse won’t respond if the cable is not connected.
Connect the cable to the TYPE-C port of the mouse and the USB port on the device. The mouse is ready to use while the indicator lights up.
When connected by cable, the mode will default to wired mode even if the toggle is in Bluetooth mode or 2.4GHz mode.

2.4GHz Mode

Switch to “6” mode (2.4GHz mode), and the mouse will automatically turn on 2.4GHz paring. The mouse indicator will slowly flash green.
Find the 2.4GHz receiver and connect it to the device’s USB port. Once successfully connected, the mouse indicator will turn green and stay on for 3 seconds, then dim off.
In 2.4GHz paring mode, the mouse indicator will slowly blink green for 3 minutes. If it’s not connected within 3 minutes, the mouse indicator will turn off. If you need to reconnect, hold both the “Left button + Forward button” for 4 seconds to re-enter pairing mode.
If you need to repair the connection in 2.4GHz mode, please unplug the 2.4GHz receiver first. Then, hold both the “Left button + Forward button” for 4 seconds, wait for the green light indicator to start flashing, and plug the 2.4GHz receiver back in to complete the pairing process.
Note: It is recommended that when pairing the mouse in 2.4GHz mode, the mouse should be within 20cm of the receiver.

Note
For the best wireless experience, we recommend using the extension adapter for the receiver and putting the 2.4GHz receiver somewhere on your desk close to your mouse for a lower rate of latency and fewer signal interferences.

Bluetooth mode

Switch to “B” Mode (Bluetooth), and the mouse will automatically turn on Bluetooth pairing mode. The mouse indicator will slowly flash blue.
Open the Bluetooth settings, search for a device named “Keychron M4”, then click “connect” to complete pairing.
When in Bluetooth pairing mode, the mouse indicator will slowly blink in blue for 3 minutes. If it’s not connected within 3 minutes, the mouse indicator will turn off. If you need to reconnect, you need to hold the “Left button +
Forward button” for 4 seconds to re-enter pairing mode. The indicator will slowly blink blue.
If the mouse is in Bluetooth mode and needs to pair with a new device, hold both the “Left button + Forward button” for seconds and wait for the blue light to flash on. At this point, Bluetooth has re-entered pairing mode, and you can connect the new device to the mouse.

How to factory reset
