Most of the time, this issue is easy to solve at home in just a few minutes. ### **Step 1: Figure Out What’s Happening** First, let’s confirm what’s going on with your system. - **Does the control box freeze?** (The screen is stuck and doesn’t respond to any button presses.) - **Or does the control box reboot?** (The screen goes dark and then comes back on the “Shiftwave 5” protocol, just like it does at startup.)  If it’s rebooting, move on to the next step. ### **Step 2: Check the Power Connections** The most common cause of random reboots is a power cable that isn’t fully connected. This can happen even if it *looks* like it’s plugged in. 1. **At the chair**: Go to the back of your Shiftwave chair where the power cable connects. - Firmly press the cable into the port until you **hear or feel a “click.”** The flat side of the connector should be facing upwards before installation into the socket. - This click means the locking sleeve has engaged. Give the cable a gentle tug. it should only release if you pull the locking sleeve back. 2. **At the control box**: Unplug the power cord from the control box, then plug it back in, making sure it’s fully connected. ### **Step 3: Test the System** - Power your Shiftwave back on. - Run a protocol for a few minutes. - If the control box stays on without rebooting, you’re all set! ### **Step 4: Still Need Help?** If your control box continues to reboot after fully inserting the power connections, we’re here to help.
