parts. Contact Black Box Technical Support at 724-746-5500 or info@blackbox.com.

complete description, including:
• the nature and duration of the problem.
• when the problem occurs.
• the components involved in the problem.
• any particular application that, when used, appears to create the problem or make it worse.
6.2 Shipping and Packaging
If you need to transport or ship your 4X4 HDMI Matrix Switch:

• If you are returning the unit, make sure you include everything you received with it. Before you ship for return or repair, contact Black Box to
get a Return Authorization (RA) number.
