How to use

Place the K-40 base unit on a desk and connect it to the room’s main display via HDMI. Laptop users can download and launch the Universal PC-Client from the unit or www.KlickandShow.com to join the meeting, or they may use an optional USB-A transmitter together with the PC-client. Mobile devices connect using AirPlay, Miracast, Chromecast or the free Android app. To present via a TOUCH transmitter, plug the chosen transmitter (HDMI, USB-C or USB-A) into the device’s port and touch the built-in sensor button to begin mirroring. Use the moderator function to manage presenters and live preview thumbnails when several transmitters are connected.

Recommendations

For best performance, connect the K-40 to the main display with a high-quality HDMI cable, place the unit where external antennas have clear line-of-sight, and use the dual-band Wi‑Fi to separate guest and staff traffic if required. Use HDMI or USB-C transmitters for true plug-and-play presentation, or USB-A with the PC-client for legacy laptops. Ensure devices use compatible video modes for optimal resolution.
