1. Image replacement on the constructions with undivided and demountable prisms.

Procedure for replacing the image:

• Remove the whole prism / removable plates (for demountable prisms)
• Transfer them to the place of the replacement image
• Lay whole prisms / removable plates into the cradle
• Remove the old image
• Label the new image on the whole prism / removable plate
• Transportation of whole prisms / removable plates to the”Prismatron” construction’s location
• Assemblage of whole prisms / removable plates

Do not allow:

1. To replace the image directly on the construction without removing the prism / removable plate. It can lead to prism’s deformation, the damage of plastic elements of the drive. Finally, it can result in the jamming of prisms and the emergency stop of wholeadvertising structure.

2. To Support the stepladder on the decorative cover.It can lead to itsdeformation and the violation of his appearance.

Recommendation:

To delete the old image from a whole prism / removable plates before the new onelabeling. If the old image is not removed, prism’s dimensions will increase and the gap between them will be reduced. That can lead to the jamming of prisms and the emergency stop of wholeadvertising structure.

2. Image replacement on the constructions with “Light” prisms.

The Image replacement on the “Prismatron” construction with “Light” prisms is made directly on the construction. This type of the construction does not require disassembles and transportation. That can be identified as a main difference between the “Prismatron” construction with “Light” prisms “prisms usage and other types of prisms.
