In some situations, you may find that your UltraSync ONE's control buttons are pressed accidentally, which can affect the settings. To prevent these accidental button presses from affecting your UltraSync ONE, you can turn on the Button Lock.
Once button lock is enabled, you cannot get into the menus unless you first deactivate the lock.
Make sure your UltraSync ONE is switched on (see Switch UltraSync ONE On and Off).
- Use the Up and Down buttons to scroll to the screen that shows Button Lock: at the top.
The Button Lock screen presents you with one of two messages:
- Press to Lock - This message is shown if button lock is currently disabled. If you press the Select button, button lock is enabled. UltraSync ONE will not allow you to access the menu options again until the button lock has been disabled.
- Press to Un-Lock - This message is only shown if button lock is currently enabled. If you press the Select button, button lock is disabled. You will be able to access the menus again by pressing the Select button.
Press the Select button to confirm.
