How to wake up your CommBox Classic S4 and put it into standby

Applies to: Classic S4, Classic S4+

You can wake the CommBox from standby in three simple ways:

Press the Power button
- Located on the front of the CommBox
- Or use the Power button on the remote control
Wake via HDMI/USB input
- If a connected device (like a laptop or Apple TV) wakes up, the CommBox will automatically power on and switch to that input.

To return the screen to standby mode:

Press the Power button once
- Either on the screen itself or the remote control
- This puts the screen into low-power standby mode while retaining quick start-up capability

💡 Tip: You can still receive scheduled updates or wake the panel easily when it's in standby.
