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.
