FACTORY SERVICE

In the unlikely event of hardware failure, service for IQ System components
should be performed by factory personnel. Crown has over 100 authorized
warranty stations across the U.S.; however, IQ System components (and
microphones) should only be serviced at the Crown Factory. Also, all Crown
hardware carries a 3-Year Full No-Fault Warranty which is fully transferrable. To
obtain service from the factory ship the defective product to:

Crown Factory Service

1718 W. Mishawaka Rd Plant 2-SW

Elkhart, IN 46517

Please enclose a letter with a brief description of the problem, where to return
the repaired product, contact name, and daytime phone number. PLEASE ship
the unit in its original factory pack to avoid shipping damage. If you have thrown
away or misplaced your factory pack you may contact the Crown Parts
Department for replacement packing material. The Crown Parts Department,
Factory Service, and Technical Support Group may all be reached at:

Phone (North America): 800-342-6939

Phone (International): 219-294-8200

Hardware Policy

Crown reserves the right to decide if a malfunctioning component will be
repaired or replaced during the warranty period. In general Crown will only
replace a defective product if the product fails within the first two weeks of
installation or if the product has been repaired three or more times in the
warranty period (the most recent being at the Crown Factory). Advanced
replacements are only available through firms who have established credit
accounts with Crown.

Firmware upgrades are not considered warranty service and are chargeable
according to the terms established by the Crown Factory Service department.
The only exception to this is if the firmware itself is somehow defective and the
only way to repair the product is to upgrade the firmware version. If you have
additional questions about firmware upgrades contact Crown.

Software Policy

All Turbo and Sys-Config software is site licensed. When an order is placed for
any of these software packages the software is built to order with the site name
embedded in the program. Developmental software is only available through
an IQ Certified consultant, contactor/dealer, or customer.

Software for demonstration purposes is available at no charge from Crown.
Demo copies of IQ For Windows are fully functional except that the demo
software does not communicate with a real system. Demo copies of Turbo
software allow full operation, including communication, however we build in an
expiration date, thus it is temporary software. Contact Crown for details.

Crown has two types of software: development and release. Release software
is software that has been heavily tested and meets design requirements so that
it is as reliable as possible. For software to be released it must also have a
finished instruction manual. In the event that a “bug” is discovered in release
