Guardian Product Return
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 trip the
telephone’s internal resettable fuse. In the event that the fuse trips, disconnect the
telephone from the power source 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 an RMA form online at
https://www.guardiantelecom.com/support/rma/
, 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.
