This document describes the AJAZZ K620T Bluetooth Dual-Mode Mechanical Keyboard, a versatile keyboard designed for various operating systems and user preferences.

Function Description:

The K620T keyboard offers both wired and Bluetooth connectivity, allowing users to switch between modes easily. A physical switch on the keyboard toggles between wired mode, Bluetooth mode (labeled "BT"), and power off ("OFF"). In wired mode, the keyboard connects directly to a computer via a Type-C data cable. For Bluetooth mode, the keyboard supports pairing with up to three different Bluetooth devices (FN+Q, FN+W, FN+E).

The keyboard features a 61-key layout and includes a knob for volume control. Turning the knob left decreases volume, turning it right increases volume, and pressing it mutes the audio.

Combination Key Functions:

The keyboard utilizes FN key combinations for various functions:

F-Keys: FN+ESC (~) to FN+=+ (F12) provide access to standard F-key functions.
Media Control: FN+Z (Previous song), FN+X (Play/pause), FN+C (Next song), FN+V (Lock screen WIN+L), FN+Right APP (Direction down), FN+Right ALT (Direction left), FN+Right ctrl (Direction right).
Lighting Control:
- FN+[ : Circular adjustment of light brightness (six gears plus off). The indicator flashes 3 times at the highest and lowest settings.
- FN+] : Cyclic adjustment of light effect speed (six gears plus light effect pause). The indicator flashes 3 times at the fastest and slowest settings.
- FN+, | : Cyclic adjustment of lighting effects (19 sets of backlight effects, following a wave pattern by default).
System and Device Functions:
- FN+B: Opens the main business in Windows, or returns to the desktop on mobile terminals.
- FN+Right: Shifts direction key/function key exchange.
- FN+Left ctrl: Interchanges the number area and the F function area. The default F key function area requires FN combination; after pressing this combination, it still requires FN for use.
- FN+space (long press 4s): Restores factory settings, clearing all configurations.
- FN+Q/W/E: Switches between paired Bluetooth devices (supports control and storage of 3 Bluetooth devices). The keyboard indicator flashes during switching, and flashes once upon successful switch.
