Periodic Maintenance
Section 10-1
Overview
10-1-1
Purpose of Chapter 10
This chapter describes Periodic Maintenance (PM) procedures for the Vivid 3N Pro/Expert ultrasound
scanner and its peripherals. These PM procedures are designed to protect your investment in the Vivid
3N Pro/Expert system, and to ensure constant operation at maximum efficiency.
After delivery and installation of the Vivid 3N Pro/Expert ultrasound unit, your service representative will
contact you to schedule the first of several routine service visits. In addition to routine maintenance by
trained Field Service Engineers (FSEs), it is recommended that the procedures described in this
chapter be observed as part of your own internal routine maintenance program.

Warnings
DANGER: There are several places on the backplane, the AC distribution box, and the DC
distribution box that could be dangerous. Be sure to disconnect the system power plug and to
open the main circuit breaker before you remove any parts. Proceed with caution whenever
power is ON and covers are removed.
DANGER: Do not pull out or insert circuit boards while mains power to the system is ON.
CAUTION: Practice good ESD prevention. Wear an anti-static strap when handling electronic
parts and when disconnecting/connecting cables.
CAUTION: Do NOT operate the unit unless all board covers and frame panels are securely in
place, to ensure optimal system performance and cooling.
When covers are removed, EMI may be present.
