Potentially defective AC line cords were sent out with systems built before the above date. These cords were
made by vendors other than Unielec. The example shown below was made by Ningbo Yunhuan. These cords
may not connect with the AC input connector on the bass module properly, resulting in intermittent operation or
other safety related problems.
The service center MUST provide a new Unielec version AC line cord to all customers that send in a SoundDock
system for repair that was built before the above date. If the customer did not send in the AC line cord with the
product, the service center MUST instruct the customer to replace the non-Unielec AC line cord with the Unielec
AC line cord, and to discard the other version. The name of the manufacturer is typically molded into the plug.
The Unielec name is molded into the plug end of the cord. Refer to the photos below.
If you have a unit in for repair that you suspect was damaged by a non-Unielec power cord, you are required to
contact Bose Corporation with information about the failure. Email the Bose Europe Customer Service group at
support_uk@bose.com or contact your local Bose representative. Be sure to include the customer's name and
address, AC cord manufacturer, system DOM and serial numbers and extent of damage to the unit.
