Yealink MCoreKit-C4-MS Native Microsoft Teams Rooms system BaseKit

Frequently Asked Questions

My MCoreKit-C4-MS won't boot or show anything on the display. What should I check first?

First, verify the power adapter is securely connected to both the mini PC and a working wall outlet. Ensure the HDMI cable is firmly attached to one of the three HDMI output ports on the MCore Pro and to your display. If the display remains blank, try a different HDMI port on the mini PC and confirm your display is set to the correct input source.

The MTouch E2 touch console is not responding to touch. How can I fix this?

Check the USB cable connecting the MTouch E2 to the MCore Pro mini PC; it must be plugged directly into a USB port on the mini PC, not into the display or a hub. If that's correct, disconnect and reconnect the cable to force a re-enumeration. If the issue persists, the touch driver may need to be reinstalled through the Teams Rooms settings.

I can't sign in to Microsoft Teams on the MCoreKit. What should I try?

Confirm that the mini PC has a wired internet connection (Ethernet) and that your network allows traffic to Microsoft 365 endpoints. If sign-in fails, check that your Microsoft Teams account is licensed for Teams Rooms (not just the free version). You can also try power cycling the mini PC and the network switch.

The automatic wakeup screen feature (CEC) isn't working. How can I enable it?

CEC functionality depends on your display's support and settings. First, ensure your display has CEC enabled in its own menu (often labeled as 'HDMI-CEC' or 'Anynet+'). Then, verify you are using the HDMI port labeled 'HDMI Out 1' on the MCore Pro, as CEC typically works only on that port. If it still doesn't work, try a different HDMI cable.

Audio from the built-in microphone on my external speakerphone is too low during calls. What can I do?

Check the audio settings in the Teams Rooms interface to ensure the correct microphone is selected and not muted. If using a third-party USB speakerphone, verify it is connected directly to the MCore Pro (not through the MTouch). You can also adjust the microphone sensitivity in the Windows sound settings accessible from the admin menu of the Teams Rooms app.

The RoomSensor is not detecting motion. How can I troubleshoot this?

Ensure the RoomSensor is properly paired with the MCore Pro via Bluetooth. Check that it has fresh batteries and is placed in a location where it has a clear view of the room, not obstructed by furniture. If the issue continues, try re-pairing the sensor through the Teams Rooms settings under 'Room peripherals'.

Can I use this system with a different video conferencing service like Zoom?

The MCoreKit-C4-MS is a native Microsoft Teams Rooms system and is designed to run only the Microsoft Teams Rooms application. It will not natively support Zoom or other services. For multi-platform use, you would need a BYOD-capable room setup or a different device that supports multiple conferencing apps.

How do I connect a wireless presentation device to the MTouch E2?

The MTouch E2 has a built-in Wi-Fi access point specifically for Yealink wireless presentation devices. Turn on the wireless presentation device and connect it to the MTouch's Wi-Fi network (the SSID is usually shown on the MTouch screen). Then, follow the on-screen instructions on the MTouch to start sharing content.

The system keeps losing its network connection during meetings. What should I check?

First, verify the Ethernet cable is securely connected and not damaged. Check that the network port on the mini PC is not faulty by trying a different port on your switch. If using a managed switch, ensure the port is not set to a low power-saving mode that might drop the link. A simple power cycle of both the mini PC and the network switch often resolves intermittent drops.

I need to update the firmware on the MCoreKit. What is the safest way to do this?

Firmware updates for the MCoreKit are typically delivered through Windows Update or the Microsoft Teams Rooms admin portal. Ensure the mini PC is connected to the internet and logged into Teams. Go to the admin settings on the Teams Rooms interface and check for updates. Allow the update to complete fully without interrupting power or network. If you have a managed deployment, your IT administrator can push updates via Microsoft Endpoint Manager.

About This Product

The Yealink MCoreKit-C4-MS is a purpose-built Microsoft Teams Rooms system designed for medium to large conference rooms where a dedicated, high-performance compute unit is preferred over a bring-your-own-device (BYOD) approach. It is ideal for organizations that are already standardized on Microsoft Teams and want a seamless, certified meeting room experience without the complexity of managing a separate PC. The kit includes a mini PC, a touch console, and a room sensor, making it a complete solution for scheduling, joining, and controlling meetings from the room itself.

This system pairs naturally with Yealink's own cameras and microphones, but it can also work with many third-party USB peripherals that are certified for Teams Rooms. A key tradeoff is that this is not a general-purpose computer—it runs the Teams Rooms software exclusively, so it cannot double as a staff workstation or run non-meeting applications. For a Toronto office deploying multiple huddle or boardrooms, the MCoreKit-C4-MS offers a consistent, IT-manageable platform, but it may be overkill for a small huddle room where a simpler USB bar or a BYOD setup would be sufficient. Conversely, it may be underpowered for a large boardroom needing complex multi-camera setups or advanced video processing beyond what Teams Rooms natively supports.

Canadian businesses should note that this system is fully compatible with Microsoft 365 tenants hosted in Canadian data centers, and its native Teams Rooms interface supports Canadian French and English. Power is supplied via an external adapter (not PoE), so ensure each room has accessible AC outlets. The inclusion of TPM 2.0 is a plus for organizations with strict security compliance requirements, such as those in finance or healthcare sectors in the GTA.
