Troubleshooting
How to Return Your Analyzer for Service
Other Packaging
CAUTION
Spectrum analyzer damage can result from using packaging materials
other than those specified. Never use styrene pellets in any shape as
packaging materials. They do not adequately cushion the equipment or
prevent it from shifting in the carton. They cause equipment damage by
generating static electricity and by lodging in the spectrum analyzer
louvers, blocking airflow.
You can repackage the instrument with commercially available
materials, as follows:
1. Attach a completed service tag to the instrument.
2. If you have a front-panel cover, install it on the instrument; if not,
protect the control panel with cardboard.
3. Wrap the instrument in antistatic plastic to reduce the possibility of
damage caused by electrostatic discharge.
4. Use a strong shipping container. A double-walled, corrugated
cardboard carton with 159 kg (350 lb) bursting strength is adequate.
The carton must be both large enough and strong enough to
accommodate the spectrum analyzer. Allow at least 3 to 4 inches on
all sides of the analyzer for packing material.
5. Surround the equipment with three to four inches of packing
material and prevent the equipment from moving in the carton. If
packing foam is not available, the best alternative is S.D.-240 Air
Cap™ from Sealed Air Corporation (Hayward, California, 94545).
Air Cap looks like a plastic sheet filled with 1-1/4 inch air bubbles.
Use the pink-colored Air Cap to reduce static electricity. Wrapping
the equipment several times in this material should both protect the
equipment and prevent it from moving in the carton.
6. Seal the shipping container securely with strong nylon adhesive
tape.
7. Mark the shipping container “FRAGILE, HANDLE WITH CARE” to
assure careful handling.
8. Retain copies of all shipping papers.
