When using your video equipment, basic safety precautions
should always be followed, including the following:
1. Read and understand all instructions before using.
2. Maximum surrounding air temperature 50°c.
3. Main disconnect must be incorporated in the ixed wiring in
accordance with the wiring rules.
4. Rated for indoor use only.
5. Use copper rated conductors rated 75°c or higher.
6. If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualiied persons in
order to avoid hazard.
7. Position the cord so that it will not be tripped over, pulled, or
contact hot surfaces.
8. If an extension cord is necessary, a cord with a current rating at
least equal to that of the appliance should be used. Cords rated
for less amperage than the appliance may overheat.
9. To reduce the risk of electric shock, do not disassemble this
appliance. Contact an authorized service dealer when repair
work is required. Incorrect reassembly can cause electric shock
when the appliance is used subsequently.
10. The use of an accessory attachment not recommended by the
manufacturer may cause a risk of ire, electric shock, or injury to
persons.
11. Failure to provide adequate structural strength for this
component can result in serious personal injury or damage to
equipment! It is the installer’s responsibility to make sure the
structure to which this component is attached can support the
weight of all equipment. Reinforce the structure as required
before installing the component.

Tools Required for Installation
Pre-Installation
1. Carefully unpack case from shipping carton.
2. Set aside the Installation Kit. Items inside will be used
during installation.
3. Make sure to recheck measurement of case for proper
installation clearance.
1/2“ Open Wrench
or Socket Driver
4. Remove any protective foam covering the outside
of the case.
5. Remove the transport safety-brackets that connect the
slatbar to the case.
#2 Phillips Screwdriver
Prepare your ceiling
1. Determine the required opening in the ceiling by measuring the case.
2. Verify your measurements with the the case dimensions that can be found in the chart on page 3.
Use the L2 dimension and the widht of the case, which is 126 mm
3. Make sure you add 8 mm all around the case dimensions and make the cut-out in the ceiling to enable placement.

1. Hang case and attach to support structure with threaded
rods and nuts. See Suggested Methods of Installation.
2. Tighten nuts until trim lange is lush with ceiling.
NOTE: For proper operation, case must be levelled side to
side and front to back.
3. If screen surface is tab-tensioned, use a #2 Phillips
screwdriver to remove white transport safety brackets
attached to slat and screen (Figure 1).
4. Connect the power cable to the Easy Install connector on the
left side of the case. (See wiring diagram.)
Case Installation
5. Test installation by running screen up and down a few times.
Be prepared to stop screen should any objects obstruct the
movement of the screen. To prevent damage to the motor,
the standard duty cycle is 1 minute on and 3 minutes of.
6. Install inishing trim covers on both ends of the case. Line up
trim cover lush with case. Magnet will hold cover in place
and secure with safety screw #2 Phillips screwdriver through
motor and pin end bracket (Figures 2 and 3).

General instructions
•
the use of the projection screen.
•
The motor has been specially developed for this projection screen and ensures
positions may be set on the motor. This has already been done at the factory.
Only change these settings slightly when absolutely necessary. Changes in
settings
•
As a result of this special construction, the motor has a limited continuous
duration of operation. For most motors, this duration is approximately
4 minutes.This is long enough to allow the projection screen to unroll and retract
several times. However, if the projection screen is used continuously for too long,
the motor will become hot and the thermal overload cut-out will automatically
automatically.This can take 15 to 30 minutes.
•
operation so that you can check to make sure that there are no persons or
obstacles under the projection screen.
•
Make sure that children are not able to play with the equipment involved in the
operation of the projection screen (wall switch, remote control).
•
Under normal use (once or twice daily) conditions, the life of the motor is at
least 10 years.The motor does not require maintenance.
Using the wall switch
•
Every electrically operated projection screen comes standardly equipped with a
rotary switch for mounting on the wall. After operation, the switch rotates back
to the zero position.This is an additional safety feature to make sure the motor is
always voltage-free when not in use.
•
Turn the switch to the right to unroll the projection screen and keep the switch
in this position until the projection screen is fully unrolled.Turn the switch to the
left to retract the projection screen.
RF remote control for projection screens with built-in RF receiver
•
The RF electrol projection screens come standardly equipped with an RF (Radio
Frequency) remote control.
•
The RF remote control works through walls and does not have to be aimed at a
•
Two projection screens with RF remote control should not be mounted within
30 cm of each other.

Troubleshooting
Symptom Solution
The projection screen does not
unroll or retract (anymore).
Check for main voltage.
Check to make sure if the plug is plugged into the socket.
Check to see if the batteries are installed properly in the remote control.
The thermal overload cut-out of the motor has been activated and has turned o the motor. Wait 15 to 30 minutes
and then try to unroll or retract the projection screen again.
Make sure the projection screen is voltage-free and check the connections as described in section ‘Connecting
DescenderPro’. Check to see if any wires are loose.
The projection screen/the
motor made a strange noise the
irst time I used it.
It is possible that an object (for example, part of the packaging) fell into the case prior to mounting. Check to see if this
is the case and whether this object is what is causing the noise.
If the motor has been damaged during transport, please contact the supplier.
The projection screen motor
is turning in the wrong
direction (reverse direction)
for projection screens without
builtin RF remote control.
Consult the connection diagrams in ‘Connecting DescenderPro ’ and switch the brown and black motor wires.
The projection screen motor
is turning in the wrong
direction (reverse direction) for
projection screens with built-in
RF remote control.
Power o the motor.
Power on the motor.
Press the program button twice (2x).
Press the down button once (1x).
