Your Zone True Wireless should automatically reconnect if your Bluetooth signal is lost during a call. If it doesn’t, it only takes a few steps to get it connected again:

1. Put your Zone True Wireless back into the charging case. 
2. After one minute, take Zone True Wireless back out of the charging case on and wait for it to connect.
3. If this doesn’t resolve the issue, you may need to restart your phone’s Bluetooth connection: 

• • Set your phone to airplane mode.
  • Wait ten seconds and then switch airplane mode off.
  • If your Zone True Wireless still doesn’t reconnect, open your phone’s settings and tap on Bluetooth.
  • Tap on your Zone True Wireless from the list of available known devices.
