You can add or release a token (if you use multiple Zappiti devices, players, and/or NAS).
Press the MENU button of your remote control, select "Settings". Then go to the bottom of the page in the last tab and find the button "Add token..."
When you press this button, a new window appears to type the new Token number.
If you want to release one of the Token saved, you just have to click on the button "Release the Token" in front of the Token concerned.
