Set screen properties for the Thor VM1.
Factory Default Settings
Note: If Automatic Brightness Control is enabled for an outdoor display, the value for LCD Brightness depends on the
Ambient Light %. Otherwise, the display defaults to 100% brightness.
Note: There is no default value for Ambient Light % as it varies depending on the level of light where the Thor VM1 is
located. If the Thor VM1 has an indoor display it does not have an ambient light sensor and the Ambient Light % is
always 0.
Note: Touch screen defroster controls are located on the Peripherals (page 5-82) control panel.
Screen Blanking
See Screen Blanking (page 4-30) for the hardware necessary for screen blanking.
Screen blanking allows the Thor VM1 display to automatically be turned off whenever the vehicle is in motion. When
the Thor VM1 display is off due to vehicle motion, the integrated keypad backlight remains on.
