Maintenance
Page 9-2
9.1. Overview
This section describes routine performance checks that you can perform to ensure that the system is
operating correctly. The performance checks listed are not intended to substitute for scheduled periodic
maintenance. If problems are found during these checks, contact a qualified service engineer to
troubleshoot and repair the system.
Prior to performing any of the performance checks in this section, it is important that potential hazards
associated with these tasks are understood. Review the "Introduction and Safety" chapter of this manual
before proceeding.
Circuits inside the equipment use voltages that are capable of causing serious injury or
death from electrical shock. Do not remove the covers or perform any type of service task,
except as specifically instructed here.
Move the system into a safe operating area prior to beginning these checks and observe all radiation safety
precautions. The performance checks should be performed as often as equipment is in use and
circumstances warrant. The frequency of performance checks should be increased when the system is
used extensively. In addition, circumstances such as accidents during transport or exposure to excessive
fluids may warrant that performance checks be performed to verify operation of the equipment.
In addition to performance checks, safe cleaning practices are included and a description of periodic
maintenance that should be performed. All periodic maintenance should be performed by a GE HUALUN
medical systems Co. Ltd. representative or a qualified service engineer.
The system should have an expected service life of 10 years. Periodic maintenance of the system is
required to maintain the system lifecycle. The first periodic maintenance shall be implemented after first 13
months of use. Then it is suggested to do once per year by a GE qualified service engineer.
