In the highly unlikely event that your UltraSync ONE becomes unresponsive and you cannot access the menus, you should try a reset:
- Press and hold both the Up and the Down buttons at the same time. Do not worry if the screen flickers a little as you hold the buttons down - this is normal.
- Keep the Up and Down buttons pressed down until the UltraSync ONE appears to switch off.
- Release the Up and Down buttons. The UltraSync ONE restarts.
When the UltraSync ONE restarts, it still has all of the settings that were in place before you reset it. If it is still unresponsive, try performing a factory reset. A factory reset will restore your UltraSync ONE's original settings so any existing settings will be lost (see Restore Factory Settings).
