5 Instructions for use

5.1 General instructions

• The projection screen is equipped with an electric tubular motor. This simplifies
the use of the projection screen.
• The motor has been specially developed for this projection screen and ensures
that the projection screen unrolls and retracts with at a constant speed. The final
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
can result in a less flat projection surface.
• 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
turn off the motor. Once the motor has cooled off sufficiently, it will turn back on
automatically. This can take 15 to 30 minutes.
• Make sure that the projection screen is within your field of vision during
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.

5.2 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.

5.3 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
specific object as is the case with an infrared system.
• See also section 3.2 'RF remote control'.
• Two projection screens with RF remote control should not be mounted within
30 cm of each other.
