MODULE EXCHANGE SERVICE
In order to provide Nautel customers with a fast and efficient service in the event of a problem, Nautel operates a factory
rebuilt, module exchange service which takes full advantage of the high degree of module redundancy in Nautel
equipment. This module exchange service is operated from Nautel’s factory in Bangor, Maine and Hackett’s Cove,
Nova Scotia. These two locations allow us to provide a quick turn around service to keep our customers on the air.
During the transmitter’s warranty period, up to thirteen months from shipment, repair and exchange of modules is at no
charge to the customer. When the warranty has expired, a charge of 80% of the list price for all exchanged modules is
made. If the faulty module is returned to Nautel within 30 days, a credit is issued reducing this charge by one half to
40% of the list price. U.S.A. customers are required to contact our Bangor, Maine facility. Canadian and overseas
customers should contact our Nova Scotia, Canada facility.

supplied without grounding the equipment, there is a risk of receiving a
severe or fatal electrical shock.
ELECTROSTATIC SENSITIVE
Indicates part or assembly is or contains devices that are electrostatic
sensitive. To prevent damage to these devices, ensure the handling
procedures outlined in this manual are observed.
WARNING A WARNING denotes a hazard. It identifies an operating procedure,
condition, etc. which, if not strictly observed or adhered to, could result in
injury or death to personnel. Throughout the technical manual, a
WARNING shall immediately precede the text to which it applies.
CAUTION A CAUTION denotes a hazard. It identifies an operating procedure,
condition, etc., which, if not strictly observed or adhered to, could result in
damage to, or destruction of the equipment. Throughout the technical
manual, a CAUTION shall immediately precede the text to which it
applies.
NOTE A NOTE denotes important information pertaining to an operating
procedure, condition, statement, etc., which is essential to highlight. A
NOTE may precede or follow the text to which it applies.
