Operating Instructions

Backlighting

The K800 features smart backlighting that automatically adjusts to the ambient light in your environment. An integrated ambient light sensor detects the surrounding light levels and brightens or dims the key backlighting accordingly. The backlighting also activates when your hands approach the keyboard and turns off when you move away, conserving battery life.

• Manual Brightness Adjustment: You can manually adjust the backlighting brightness using the dedicated brightness keys (usually F5 and F6) on the keyboard.
• Proximity Detection: The keyboard uses proximity sensors to detect your hands, illuminating the keys as you approach and dimming them when you move away.

Typing Experience

The PerfectStroke key system and Logitech Incurve keys are designed for a comfortable and efficient typing experience. The keys are quiet and provide a smooth, responsive feel.

Media Keys and Function Keys

The keyboard includes dedicated media keys and customizable function keys (F1-F12) for quick access to various controls and applications. These can be configured using the Logitech Options software.

• Media Controls: Play/pause, volume up/down, mute, and track navigation.
• Customizable Functions: Assign specific actions or shortcuts to the F-keys for personalized workflow.

Charging the Keyboard

The K800 uses a rechargeable battery. When the battery is low, the battery indicator light will signal the need for charging. Connect the micro-USB cable to the keyboard and a power source. You can continue to use the keyboard while it is charging.

• Battery Life: A full charge can provide up to 10 days of battery life, depending on usage and backlighting intensity.
• Charging Indicator: The battery indicator lights will show charging status and when the battery is full.
