SHOCK HAZARD!
When the bulk 12V power supply is removed from the oscilloscope, two AC leads are exposed.
Therefore, the power cable should be disconnected from the bulk 12V power supply before the
supply is removed. Caution should also be exercised to not contact these leads as severe shock
could result.
To return the oscilloscope to Agilent Technologies for service
Before shipping the oscilloscope to Agilent Technologies, contact your nearest Agilent
Technologies oscilloscope Support Center (or Agilent Technologies Service Center if outside the
United States) for additional details.
1
Write the following information on a tag and attach it to the oscilloscope.
• Name and address of owner
• Oscilloscope model numbers
• Oscilloscope serial numbers
• Description of the service required or failure indications
2
Remove all accessories from the oscilloscope.
Accessories include all cables. Do not include accessories unless they are associated with the
failure symptoms.
3
Protect the oscilloscope by wrapping it in plastic or heavy paper.
4
Pack the oscilloscope in foam or other shock absorbing material and place it in a strong
shipping container.
You can use the original shipping materials or order materials from an Agilent Technologies Sales
Office. If neither are available, place 8 to 10 cm (3 to 4 inches) of shock-absorbing material around
the oscilloscope and place it in a box that does not allow movement during shipping.
5
Seal the shipping container securely.
6
Mark the shipping container as FRAGILE.
In any correspondence, refer to oscilloscope by model number and full serial number.
