Unpack the UPS carefully, notice the packing method, and retain the box and packing material. (If you 
must return the UPS at any time, repack it how it was originally shipped.) Visually inspect the UPS for 
damage which may have occurred during shipment. If there is damage or anything is missing, contact 
the dealer from whom you purchased the unit, and save the packaging for future shipment. When the 
unit has passed the initial inspection, record the purchase date on the back panel of the unit and in the 
space provided in the front of the manual.
