Do not remove 12 V power from display until the LED light is black. Prematurely removing power (green or orange light status) can cause loss of data and/or the display to lose functionality. It can take up to 20 seconds after removing key power for the LED light to completely go black.

The display must always be allowed to completely power down (LED light turns off) whenever the key is placed in the STOP position. Failure to do so can result in lost or corrupted data when power is restored.

When setting up the display with vehicle key in the accessory position (power on, engine off), turn key to STOP position for 20 seconds BEFORE starting the vehicle. This ensures that setup data is saved to the internal memory before operating.

If the vehicle is running during setup and programming, turn off vehicle with key in the STOP position and wait 30 seconds before restarting. This ensures that all data is saved to the internal memory.

DO NOT turn the key to the start position directly from the accessory position. The reduction in voltage during the starting phase could result in a loss of all setup data.

DO NOT turn the key to the start position directly from the run position. Starting the engine causes a drop in current, which can restart controllers in the wrong order as well as cause data loss on the display.

If changes are made while machine is in auxiliary mode, turn key off and wait for display power light to turn off before starting the ignition. This allows display to shut down and save data.
