LCD Touchscreen Display Time

You can choose the length of time the touchscreen remains on after the last keypress. The power-on default is 30 seconds from the last keypress. Setting the LCD Touchscreen Display Time also changes the length of time the Backlight stays on, if activated.

To change the LCD Touchscreen Display Time, follow these steps:

1.Press and hold the SETUP key on the rubber keypad until the LED indicator light remains on and the touchscreen shows the Main Setup Screen. This process takes approximately 2-3 seconds.

2.Release the SETUP key.

3.Press and release the SETUP key again. The LED indicator light blinks to acknowledge the keypress and the Digit Setup Screen is shown.

4.Press and release a digit key (1-9) to indicate the length of time you wish the touchscreen to remain on. (The RCU900 can only accept the following options: 1=10 seconds; 2=20 seconds; 3=30 seconds, etc.) Ninety seconds is the longest length of time allowable. The LED indicator blinks once to acknowledge the keypress.

5.Press and release the LCD ENTER key to save the setting. The touchscreen returns to the Main Setup Screen.

6.The LCD Touchscreen Display Time setting is now complete.

7.Press LCD CLEAR on the Main Setup Screen to exit Setup Mode.

Backlighting

Backlight illumination is only activated when you press the LIGHT key on the rubber keypad. Pressing the LIGHT key will also activate the LCD touchscreen display. After you press the LIGHT key, the backlighting remains on for 30 seconds, (or however long the LCD Touchscreen Display Time is set to), if no other commands are given.

If a command is entered after the LIGHT key has been pressed, the Backlight illumination continues for a further 30 seconds after the command is completed. Once the Backlight time has run out, the Backlight does not re-activate until the LIGHT key is pressed again. If the Backlight illumination is on, and the LIGHT key is pressed again, the Backlight turns off.
