EQUIPMENT RETURNS
In the event the equipment requires return for factory service, please follow the
guidelines listed. Comwave cannot be held responsible for damaged equipment received
due to improper packing. Contact Comwave with any questions or concerns regarding
returning or packaging of equipment.
1. Contact Comwave: Call Comwave to report the problem and to obtain a “Return
Authorization” number (RA). This enables Comwave to accurately track and identify
returned equipment for prompt and efficient service. If you do not obtain an RA
number prior to sending equipment back Comwave cannot be held responsible for
delays in receiving the equipment. These delays will inevitably cause time loss in
repairing and returning your product to you.
2. Obtain packaging materials: Use original boxes and packing materials when
returning any equipment. This will safeguard against most ill-transit damages. If
original boxes and packing materials are not available, contact Comwave to obtain
replacement materials prior to shipping. Replacement materials are provided at a
nominal cost.
3. Pack egyp' ment: Use original packing materials and directions provided. Most
equipment is packed in a box within another box; this varies with each product.
Double boxing provides maximum protection.
Caution: Do not pack equipment using "PEANUIS. ' Equipment packed using “PEANUTS” as
filler does NOT provide sufiicient protection during shipping. Rough handling by the carrier may
cause permanent damage to the equipment being returned. COM WA VE cannot be held responsible
for damaged equipment received due to improper packing.

box tape over the bottom seam, using three layers,
to assure strength. Then put 4 pieces of fiberglass
strapping tape over the edges.
2. Place the cardboard tube in the box as shown in
figure 20-0002-3.
3. Place the polyethylene endcaps against the sides of
the equipment as shown in figure 20-0002-4. WOTE

assure strength. Then put 4 pieces
of fiberglass strapping tape over
the edges. Clearly mark the RA
