Unpacking
Carefully remove the 8310 from the shipping container.
Save the container and packing materials as they may be used to transport the 8310 to
the site or for shipping the unit back to the factory.
Note: If you want to return a unit to the factory, first fill out the Product Return Sheet located at
the back of this manual and then call the factory (703-406-2800) for an RMA number. This
