Installation
This section describes the unpacking, inspection, installation, and operation of the Symmetricom 5401 and 5402 Disciplined Rubidium Oscillators.
Unpacking and Inspection
The DRO is packaged in one shipping container. Inspect the unit for visible damage (scratches, dents, etc.). If the instrument is damaged, immediately notify both Symmetricom and the responsible carrier. Keep the shipping container and packing material for the carrier's inspection.
