Guardian products have been quality tested and are in full working order when 
shipped from the factory, given the rugged nature of these products, shipping is not 
expected to damage a unit. In the unlikely event of a malfunction, Guardian follows the 
three step procedure below. 

Step I - On-Site Correction 
•  The most common source of difficulties with a new product is improper installation 

in one of two ways: incorrect wiring connections or connection to an incorrect 
power source. 

•  Product wiring needs to be properly connected to the on-site wiring. Correct wiring 

instructions are shown in the user manual included with the product. 

•  Connecting a telephone to a standard power source, rather than tip & ring, will 

blow the telephone’s internal, user-replaceable fuse. In the event of fuse burn-out, 
disconnect the telephone from the power source, replace the fuse, and reconnect 
following the wiring diagrams provided with the product. 

Step II - Return Materials Authorization (RMA) 
•  When a product has been installed following user manual instructions, and the unit 

fails to operate, the user must contact Guardian Telecom to obtain authorization to 
return the product.  This can be done by completing a RMA form online at 
www.guardiantelecom.com, or by calling the service telephone number given in 
this manual. 

•  After providing information on the product, the owner and the nature of the 

problem, Guardian will issue a RMA number, to be shown on documentation 
returned with the product. 

•  In addition to the RMA number, shipping documents should include name, address 

and telephone number of the owner along with contact information for the person 
responsible for the repair and/or the user who identified the malfunction. 

•  (Where a product is being returned for repair from outside of Canada, customs 

documentation must show the product’s serial number, date of export [date of 
purchase], and a notation that the equipment is: “Canadian goods returning.”) 

Step III - Factory Authorized Service 
•  Once received, each product is carefully inspected and tested. If the product is 

under warranty, repairs are completed and the product returned to the owner, 
generally within five working days of receipt by the factory. 

•  A product that has been subjected to misuse, neglect or accident or is beyond the 

warranty period will be evaluated. The service department will provide the owner’s 
representative with a repair cost estimate. Once approved, repairs are completed 
and the product returned, generally within five working days.
