O-9. PACKAGING. Original Puckuging. Containers and materials identical m rhose used in facmry packaging arc

available through Hewlett-Packard offices. If the insuument is being rammed m Hewlett-Packard for servicing, attach a tag indicating the rype of service required, return address, mcdel number, and. full serial number. Also mark the container FRAGILE m assure careful handling. In any

correspondence refer to the insmment by model number and full serial number.

Other PacKaging.

The following general insmxtions should be used for repackaging with

commercially available mat&&:

I. Wrap the insuument in heavy paper or plastic. (If shipping m a Hewlett-Packard office or

sen4ce center, attach a tag indictig the service rqulr-ed m xlckss, mcdd

number,

and full

serial number.)

2. Use a strong shipping container. A double wall carton made of 2.4 MPa (350 psi) test material is aaequate.

3. Use enough shock-absorbing material (75 m 100 mm layer, 3 m 4 in.) around all sides of the insuument m provide Frm cushion and prevent movement in dx container. Protect the front panel withcardboard.

4. Seal the shipping container securely.

5. Mark the shipping container FRAGILE m ensure careful handling.

l-l. DESCRIPTION AND USE OF OPERATOR’S CONTROLS,

INDICATORS, AND CONNECTORS.

This paragraph describes all of the operator controls and indicators for the Signal Generator. Due to the large number of controls and indicators on the front panef, it is necessary to sepruate the panel into five different tmrtions. Figure l-l (views A thm E) shows each Dortion of the front baneI. The rear panel is shown in figure 1-2.
