1.2 First Steps
1.2.1 Unpacking and Inspection
Your new equipment is shipped in a special packing, protecting it against
mechanical shock during transit. Care should be exercised when unpacking
so that the surfaces do not get marred.
Verify that the content of the packing agrees with the items listed on the
enclosed shipping list.
Check the condition of the equipment for signs of shipping damage. If
there should be any complaints you should immediately notify the for-
warding agent and your nearest Studer distributor.
Please retain the original packing material because it offers the best pro-
tection in case your equipment ever needs to be transported.
