Logitech K400 Plus Wireless Touch Keyboard – An Integrated Home‑Theatre Companion

The Logitech K400 Plus Wireless Touch Keyboard is a compact, all‑in‑one device that combines a full QWERTY keyboard with a built‑in touchpad and media controls. Designed for use with smart TVs, set‑top boxes, streaming devices, and PCs, it delivers effortless navigation without the clutter of separate peripherals.

Key Design Features

• Slim, low‑profile chassis – The keyboard measures only a few millimetres in height, making it easy to slide into tight spaces or rest on a coffee table.
• Quiet, membrane key switches – Each keystroke is soft and silent, ideal for living rooms where background noise should stay minimal.
• Integrated touchpad – A responsive pad sits beneath the keys, allowing cursor movement, scrolling, and multi‑touch gestures without leaving the keyboard surface.
• Dedicated media buttons – Volume up/down, mute, play/pause, forward, rewind, and home are all accessible via a single row of large, tactile icons.

Wireless Connectivity

The K400 Plus operates on a 2.4 GHz RF wireless link, which offers reliable performance up to 10 metres from the receiver. A small USB dongle plugs into any standard port, and the keyboard pairs automatically upon first use.

Keyboard Layout – UK QWERTY

With a UK‑standard QWERTY layout, the device includes the correct placement of keys such as “£”, “@”, and the distinct arrangement of the “Z” and “Y” keys. This makes it an excellent choice for users who prefer or require UK typing conventions.

Touchpad Functionality

• Multi‑touch support – Pinch to zoom, two‑finger scroll, and tap gestures work seamlessly on compatible devices.
• Precision cursor control – The touchpad’s surface is engineered for accurate pointer movement, reducing the need for a separate mouse.
• Customisable shortcuts – Users can assign specific actions to touchpad gestures via Logitech software on supported platforms.

Media Control Capabilities

The K400 Plus includes a dedicated media bar that allows instant control over playback. Whether you’re watching a movie, listening to music, or navigating a streaming service, the large icons provide quick access without interrupting your viewing experience.

Power and Battery Life

• Rechargeable lithium‑ion battery – The keyboard comes precharged and can be recharged using the included USB cable.
• Up to 12 months of standby time – When not in use, the device enters a low‑power mode that conserves energy.
• Auto‑sleep feature – After a period of inactivity, the keyboard automatically powers down and wakes instantly when you type or touch the pad.

Compatibility Overview

The K400 Plus works with:

• Windows PCs (10 / 11) – plug‑and‑play via USB receiver.
• Mac OS – supported through standard Bluetooth or USB connection.
• Android TV, Chromecast, Roku, Apple TV – all major smart‑TV platforms recognize the keyboard as a generic input device.
• Chrome OS and Linux distributions that support HID devices.

Typical Use Cases

1. Home theatre control – Replace bulky remotes with a single, silent keyboard that lets you type search queries and navigate menus.
2. Streaming media navigation – The touchpad’s gestures make scrolling through long lists of titles effortless.
3. PC productivity in tight spaces – When working from a couch or sofa, the keyboard provides a comfortable typing surface without needing a separate mouse.
4. Gaming and media editing – The quiet keys are suitable for low‑noise environments while still offering responsive input.

Maintenance Tips

• Clean the keyboard surface with a soft, dry cloth; avoid liquids that could seep into the membrane.
• Re‑charge the battery regularly to maintain optimal performance.
