Backlight illumination is generated by an Electroluminescent (EL) panel that gives a blue light, which lets you see the touchscreen and the keys in the dark. Backlight illumination is only activated when you press and release the BACKLIGHT key on the rubber keypad. Pressing the BACKLIGHT key will also activate the LCD touchscreen display. After you press and release the BACKLIGHT key, the light remains on for the power-on default of 10 seconds (or the length of time previously programmed) if no keys are pressed.

If another key is pressed after the BACKLIGHT key, the illumination continues for another 10 seconds (or the length of time previously programmed) after the key is released. Once the Backlight time has expired, the Backlight does not re-activate until the BACKLIGHT key is pressed again. If the Backlight illumination is on, and the BACKLIGHT key is pressed again, the Backlight turns off.

To change the duration of the Backlight On Time, follow these steps:

1.Press and hold the SETUP key on the rubber keypad for

2-3 seconds until the LED indicator light remains on and the touchscreen shows the Code Setup Mode? Screen.

2.Release the SETUP key.

3.Press and release the SETUP key repeatedly until the Set More Options? Screen appears. Press and release the LCD OK key.
