Projection surface damage in case of faulty assembly or set up.
Make sure all frame parts assembled correctly and all hinges and joints are locked before one unfold and
attach the projection surface.
FRAME AND LEG COMPONENTS
Please be careful
not to pinch
your ngers!
FALLING OVER
WARNING
Falling over of a projection screen can cause severe injury or death!
To avoid falling over:
• Make sure that the projection screen is in level.
• Mind the maximum set-up height of the legs
• Prevent air draft
• Use additional weights on the base prole of the leg to gain higher stability.
• Do not put additional load on the screen frame!
• Do not use outdoors!
Foldable snap joints, corner hinges and plug-in connections can
lead to injury to the hands (body parts). Please be careful not to
pinch your ngers!
Danger of injury due to improper assembly.
Make sure all frame parts assembled correctly and all hinges
and joints are locked before raising screen to standing
position. Falling parts can cause severe injury or death!

WARNING
Vario Curve systems are developed for indoor use only.
Failure to follow warning may result in personal injury due to unforeseen acts of nature.
Any damage and consequential damage caused by outdoor use is not covered by warranty.
BASIC SAFETY REQUIREMENTS
Basic safety requirements for „ying“ projection screens and wall- or ceiling mounting!
If persons are able to stand under the loads, fastening points and slings must not be loaded more than
half the value of the load bearing capacity stated by the manufacturer.
When planning the event or production, not only dead loads but also dynamic forces, potential
breakdown loads and additional loads during operation, as well as during assembly and dismantling
must be taken into account.
Observe the local safety regulations!
FLYING SCREEN
If a modular projection screen is used as a “ying” (free hanging) screen, then all plug-in and clamp
connections must be secured against becoming loose and falling.
It is not allowed to use the projection surface holding the frame parts in position!
Falling parts can cause severe injury or death!
Please make sure that all components are secured safely before raising screen to standing position
and lifting. Use the necessary number of suspension points (e.g.: EasyFly) according to the overall
system weight. A second/auxiliary safeguarding system is mandatory (e.g. steel rope catch)
Please follow the detailed instruction in the manual.

WALL MOUNTING
Before mounting, make sure that the wall, as well as the xing points meet the safety requirements of
the local standards and the required load can be beared.
Danger of injury
due to improper
disassembly.
Falling parts can
cause severe injury
or death!
Beware of
pinch points.
It is not allowed to use the projection surface holding the frame
parts in position! Falling projection screens or parts can cause
severe injury or death!

DISASSEMBLY
For disassembly the same safety instructions apply as for assembly and set up. Bring down a projection
screen with the appropriate number of people to avoid falling over of the screen.
OPERATION, MAINTENANCE AND SERVICE
FRAME ELEMENTS, LEGS AND ACCESSORIES
The frame elements, legs and additional elements are maintenance-free.
PROJECTION SURFACE
PACKAGING AND STORAGE
The projection surface is rolled on a tube with foam intermediate layer and depending on size
packed in a cardboard box or transport tube, to avoid any damage by the frame parts,
bleaching and discoloration. After use, the projection surface must be rolled up, identical to the delivery
condition, with the foam intermediate layer and with the projection side inwards in order to avoid soiling
and damage to the surface. The surface must be rolled up in such a way that the reinforced black border
with the caps and hooks never gets in contact with the projection area. Insert the enclosed foamed
plastic foil between the caps and hooks and the projection area to avoid permanent marks. Incorrect
storage can damage and discolor the surface and is not covered by the guarantee.
Additionally, following instructions have to be adhered to:
• Do not allow the projection surface to get in contact with sharp objects!
• Do not bring printed and coloring objects (instructions, magazines, etc.) in contact with the surface!
• Do not write on the projection surface!
• Colors penetrate the projection surface and cannot be cleaned anymore!
• Store the projection surface cleaned and dry at room temperature only!
COLD BREAK
A projection foil must never be stored or transported below 5° C. There is a risk of a cold break!
The lm becomes very brittle and splinters like glass! When transporting the projection surface at low
temperatures do not unroll the surface unless it has reached its full elasticity at room temperature.
Otherwise there is the risk of cold break of the projection screen.
The ideal temperature range to prevent damaging the surface during surface attachment is 54°-82° F
(12°-28° C). Assembling below recommended temperatures may damage surface and void warranty.
CLEANING OF THE PROJECTION SURFACE
Use a white clean cotton cloth saturated with clear water (optionally mild soap water) and gently
wipe the area in one direction (no circular motion). Wipe dry with another cotton cloth.
To clean a stubborn stain, use methylated spirit and follow the same procedure.
Clean rear projection surfaces in case of imperative only!
Danger of injury
due to improper
disassembly.
Falling parts can
cause severe injury
or death!
Beware of
pinch points.
Please be careful
not to pinch
your ngers!
