If You Need to Return the Modem to Us
Contact 3Com Technical Support. If the support
representative determines that you need to return the
modem, you will receive a USO (User Service Order)
number. You must have a USO number before returning
the modem to us. Ship the unit, postage paid, in a strong
box made of corrugated cardboard with plenty of packing
material. DO NOT send the modem back in the original
box. Send ONLY the modem (NOT manuals, diskettes, CDs,
etc.). Include your USO number, name, and address on the
shipping label as well as inside the package. If possible,
send the package via a courier capable of tracking the
progress of the shipment. Ship to the following address:
