Returning a
491 for service
If you have overnight or second-day shipping requirements, before ship-
ping the 491, please call Northstar for turnaround time, freight charges,
and payment arrangements.
The 491 should be shipped only in a properly designed carton with pack-
ing material. Shipments to the Northstar factory should be made to the
following address:
Northstar
Service Department
30 Sudbury Road
Acton, MA 01720 USA
Before returning the 491
to the factory, to prevent
delays it is critical that
you first obtain a Return
Materials Authorization
(RMA) number from the
Northstar Service
Department. If the 491
was purchased through a
dealer, call the dealer
with the 491 serial
number so they can help
you get an RMA number.
The 491’s serial number
can be found on the label
at the top of the 491.
Shipments without a
proper RMA number will
not be accepted!
NOTE: Return the transducer to its manufacturer, not to
Northstar.
