In the event the customer finds any noncompliance or malfunctions of the collimator, contact 
Ralco via e-mail at the address: [email protected] (Ralco Assistance).
The information must include:
• The model and serial number of the collimator found on the label.
• A detailed description of the problem (in Italian or English).
• It is important to specify if you want a repair or a total refurbishment of the product.
Ralco will resolve the problem by either providing directions, and/or field service or by sending 
replacement parts.
In the event the collimator needs to be repaired at Ralco, customer service will immediately 
provide the customer with a RMA (Return Merchandise Authorization) number as your consent 
to the return and provide all necessary additional information.
The shipping of the unit is at the customer’s expense if the unit is out of warranty, see

Your collimator contains materials which can be recycled and reused. Specialised companies 
can recycle your product to increase the amount of reusable materials and to minimize the 
amount of materials to be disposed of.
The product contains lead which can be highly contaminating if dispersed 
incorrectly. The following symbol signifies that the product conforms to the 
environmental requirements of directives 202/95/EC, 2002/96/EC, 2003/108/EC; 
it must be disposed of correctly at the end of its life-cycle.
The collimator does not contain polluting materials or products with the exception 
of the lead that composes the shutters - avoid direct contact with lead especially for prolonged 
periods.
It is required that you observe Local Laws regulating the disposal of the collimator using 
certified environmental management entities. Should this prove impossible, return the 
collimator to Ralco at the purchaser's expense and Ralco will undertake its correct disposal.
If you are replacing the unit with new equipment, you may return the old collimator to Ralco. 
Please contact us if you require further information.
