Maintenance
The network analyzer does not require any special maintenance. Make sure that the air vents are not
obstructed. The outside of the instrument is suitably cleaned using a soft, lint-free dust cloth.
Attention!
Never use solvents such as thinners, acetone and similar things, as they may damage
the front panel labeling or plastic parts.
The address of our support center and a list of useful contact addresses can be found on the Contact
page.
Storing and Packing
The network analyzer can be stored at the temperature range quoted in the data sheet. When it is stored

The original packing should be used, particularly the protective caps at the front and rear, when the
instrument is to be transported or dispatched. If the original packing is no longer available, use a sturdy
cardboard box of suitable size and carefully wrap the instrument to protect it against mechanical damage.

incompatible with each other or with the current analyzer state. These errors are generally self-
