Keychron K13 Max Quick Start Guide

Introduction

If you are a Windows user, please find the appropriate keycaps in the box, then follow the instructions below to find and replace the following keycaps:

Locate the Windows keycap and the Alt keycaps in the accessory box.
Carefully remove the existing Mac-specific keycaps (e.g., Command, Option) from the keyboard.
Install the Windows keycap in the position of the Command key and the Alt keycaps in the positions of the Option keys.

1. Connect 2.4GHz Receiver

Connect the 2.4GHz receiver to your device's USB port. Ensure the keyboard's toggle switch is set to 2.4GHz mode (indicated by 'G').

Keyboard Toggle Switch: Set to 'G/Cable/BT' and select 'G' for 2.4GHz mode.

Note: For the best wireless experience, Keychron recommends using the extension adapter for the receiver and placing the 2.4GHz receiver close to the keyboard to minimize latency and signal interference.

2. Connect Bluetooth

Ensure the keyboard's toggle switch is set to Bluetooth mode (indicated by 'BT').

Keyboard Toggle Switch: Set to 'G/Cable/BT' and select 'BT' for Bluetooth mode.

To pair with a device named Keychron K13 Max, press the fn + 1 keys simultaneously for 4 seconds until the keyboard enters pairing mode.

3. Connect Cable

5. The Layers

The keyboard features four layers of key settings:

Layer 2 and Layer 3: For the Windows system.

If your system toggle is switched to Mac, Layer 0 will be activated. If switched to Windows, Layer 2 will be activated. When using Windows mode, make changes to Layer 2 instead of Layer 0 to avoid common mistakes.
