OLLING THE BACKGROUNDS IN AUTOMATIC MODE
Select desired background number, than press the "auto up" or "auto down" button. Keep it pressed until
you hear the "beep" sound. Release the button and let the background roll automatically up or down.
You can interrupt background movement at any time, by pressing any button on the remote controller.
Note: stop level precision is ½ of one motor turn, if you need to adjust the background more precisely,
use the manual mode.

OLLING ALL BACKGROUNDS UP
Press the "all backgrounds auto up" button and keep it pressed until you hear the "beep" sound.
Release the button and let all backgrounds roll automatically to preset top levels. You can interrupt
background movement at any time, by pressing any button on the remote controller. It is good practice
to roll all backgrounds up while the system is not in use.
SETTING BACKGROUND STOP LEVELS
Choose the background for which you want to set a new stop level. Using manual roll up/down buttons position the
background at desired stop level (high or low). If you wish to set the high stop level, press 'FN' and 'Auto
Up / Set High Position' buttons simultaneously. Keep them pressed until you hear a long 'beep' signal
(second signal after a short 'beep'). The digits in the display will start to blink indicating that the new
stop level has been programmed. To program low stop level, press 'FN' and the 'Auto Down / Set Low
Position' button.
SETTING MOTOR DIRECTION (BASED ON EXPAN MOTOR POSITION)
Depending on the position of the expan motors (on left or right hand side of the backgrounds), you may need to set
motor direction. Otherwise motors will roll the backgrounds in the opposite direction to buttons pressed on the
remote controller.
To change the motor direction, press 'FN' and '5' buttons simultaneously. Keep them pressed until you hear a long
"beep" signal (after a short "beep"). The digits in the display will start to blink indicating that the motor direction has
been changed. This operation need be done only once when the system is first installed.
