TN’s total liability in connection with the products and installation thereof to
all persons and from all causes in the aggregate whether in contract, tort, or
strict liability shall not exceed the amount paid to TN for the product directly
related to the alleged damage. However, in no event shall TN have any
liability to a customer or any third party with respect to a product
manufactured in accordance with customer’s specifications.
C. Return Procedure
Before TN item(s) can be returned, a Credit Return Authorization (CRA),
Return Material Authorization (RMA), or Material Repair Authorization
(MRA)number must be obtained from TRANSITION Networks (TN) or the
distributor of origin.
Locate the serial number(s) of the item(s) to be returned. From the item serial
number, TN or the distributor will verify the return status and provide the
appropriate number to the End User. The three types of return numbers are
listed below:
• A Credit Return Authorization (CRA) number can only be requested from
your distributor. This CRA number will only be issued to distributors for
item(s) within 90 days from the original ship date. Under no
circumstances will a CRA number be issued directly to the End User. The
return item(s) must be shipped freight prepaid, by the End User or the
Distributor to TN.
• A Return Material Authorization (RMA) number can be requested from TN
or your distributor. This RMA number is only issued for item(s) after 90
days from the original ship date but prior to the expiration of the warranty
period. The return item(s) must be shipped freight prepaid, by the End
User or Distributor, to the TN address below:
TRANSITION Networks Inc.
6475 City West Parkway
Eden Prairie, MN 55344 USA
TRANSITION Networks will repair or replace the unit, at its discretion,
and cover the cost of the return freight to the distributor or End User who
was issued the RMA number.
• A Material Repair Authorization (MRA) number can be requested from TN
or your distributor. This MRA number is only issued for out-of-warranty
item(s). The return item(s) must be shipped freight prepaid, by the End
User, to the TN address above. The sender will be contacted by TN after
the item(s) have been received, inspected, and a cost estimate of the
repair has been determined. The repair charges may be billed, with
approval, through your distributor or prepaid/C.O.D. basis through the
End User. In either case, charges will include freight, both ways, and
repair charges.
The return authorization number is only valid for 60 days from the date of
issuance. Please list this number on the outside of the carton and/or packing
list. Include a copy of the original invoice or packing slip to expedite
processing.
D. Restocking Fee
All returns for credit must be received in the same condition as originally
shipped. If TN determines that a returned product is damaged due to improper
packaging or if the item is functional and returned because of customer error,
inability to use, etc., TN reserves the right to charge a minimum 15% ($10.00
minimum per item) restocking fee, the payment of which is a condition
precedent to the repair and/or return of the product.
