For repair, calibration, and to ensure the N2790A performs to its
warranted specifications, send the probe to an Keysight Service Center for
calibration testing procedures. The probe should be tested once a year or
as required by other standards. If repair is needed and the N2790A is
under warranty, normal warranty services will apply. If the N2790A is not
under warranty, repair costs will be applied.
To return the probe to Keysight Technologies for service, call
(877) 477-7278 for further details and the location of your nearest
Keysight Technologies Service Office.

shock-absorbing material and place it in a strong shipping container.

inches of shock-absorbing material around the instrument and place it
in a box that does not allow movement during shipping.
