In case you need to perform a factory reset on Crestron TSS-1070 display, you need to keep pressed the reset button on the back of the display (the small gap) until the display goes black. When the screen is black, release the reset button.
When the Crestron logo is displayed on the screen, press the reset button again until the screen is black. Repeat this 11 times until the option to ‘Factory Restore Menu’ is displayed.
Select this option and confirm with ‘Yes, I want to restore all settings to default and lose all custom settings.’ Then the display will reboot.
