Operating Instructions
Understand the key functions and controls of your PRO X TKL keyboard.
Basic Keyboard Usage
The keyboard functions as a standard QWERTY layout keyboard for typing and general computer use. The tenkeyless design removes the numeric keypad for a more compact form factor, ideal for competitive gaming setups that require more mouse space.
Game Mode Control
Activate Game Mode to disable certain keys (e.g., Windows key) that might interrupt gameplay. This can be configured and toggled via the Logitech G HUB software or a dedicated key on the keyboard (often indicated by a joystick icon).
Media Controls and Volume Roller
Dedicated media keys (Play/Pause, Stop, Previous, Next) and a volume roller are located on the top right of the keyboard for convenient audio control without exiting your application or game.
LIGHTSYNC RGB Lighting
Customize the per-key RGB lighting using Logitech G HUB. You can choose from various effects, colors, and synchronize lighting with other Logitech G LIGHTSYNC-enabled devices.
Programmable Keys
Utilize Logitech G HUB to assign custom functions, macros, or keybinds to specific keys, enhancing your productivity and gaming performance.

Features Overview
The PRO X TKL keyboard is designed with specific features to enhance your gaming and typing experience.
Tenkeyless (TKL) Design
The compact TKL form factor removes the numeric keypad, providing more desk space for mouse movement, which is crucial in competitive gaming. This design also makes the keyboard highly portable.
GX Brown Tactile Switches
This specific model features GX Brown tactile switches, which provide a noticeable bump feedback upon actuation, offering a balance between typing and gaming. They are quieter than clicky switches but provide more feedback than linear switches.

Dual-Shot PBT Keycaps
The keyboard is equipped with durable dual-shot PBT keycaps. PBT (Polybutylene Terephthalate) plastic is known for its resistance to wear, shine, and fading, ensuring the legends remain clear over extended use.
Maintenance
Proper maintenance helps extend the lifespan and performance of your keyboard.
Cleaning
- General Cleaning: Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution to wipe down the keycaps and chassis. Avoid harsh chemicals or abrasive materials.
- Dust Removal: Use compressed air to remove dust and debris from between the keycaps. For deeper cleaning, keycaps can be carefully removed using a keycap puller (not included) to clean the switch area.
Battery Care
To maximize battery life, avoid fully discharging the keyboard frequently. Recharge the keyboard when the battery indicator shows low power. Store the keyboard in a cool, dry place when not in use for extended periods.
