Repackaging for Shipment
If the unit is to be shipped to Keysight for service or repair, 
make sure that you do the following.
• Attach a tag to the unit identifying the owner and 
indicating the required service or repair. Include the 
model number and full serial number.
• Place the unit in its original container with appropriate 
packaging material for shipping.
• Secure the container with strong tape or metal bands.
• If the original shipping container is not available, place 
your unit in a container with at least four inches of 
compressible packaging material around all sides for the 
instrument. Use static-free packaging materials to avoid 
additional damage to your unit.
Cleaning
Clean the outer area of the instrument with a soft, lint-free, 
and slightly dampened cloth. Do not use detergent. 
Disassembly is not required for cleaning. 
Keysight suggests that you always insure your shipments.
