5 Troubleshooting
5.1 Introduction
This chapter lists the problems that may occur during use of the monitor and recommended measures. Refer to the table
in this chapter to check the monitor, and confirm and fix these problems. For more information about the
troubleshooting, please contact the after-sales service department of Mindray.
5.2 Part Replacement
For the monitor, the PCB, main parts and components can be replaced. For the LCD or touch screen fault, only the front
case assembly can be replaced. Once the faulty PCB is confirmed, replace the PCB according to the operation guide in
Chapter 7 Repair and Disassembly. Then, confirm that the monitor can operate normally and has passed all the
performance tests. For the information about replaceable parts, refer to Chapter 8 Parts.
5.3 Check before Powering on the Monitor
After the AC power supply is connected, check whether the AC indicator is turned on. If not, confirm whether the AC
cable is connected to the socket and monitor reliably. If both the AC external power supply and power cord are
connected normally, but the AC indicator is off, the AC-DC power module or main control board of the main unit may be
damaged. Now, you need to insert a battery to see whether the monitor can be powered on. If it cannot be powered on,
the main control board may be damaged or the internal board is abnormal, resulting in power supply protection. If the
monitor can be powered on, the AC-DC power module is damaged.
In addition, check the appearance for damages before powering on. Particularly, when the touch screen of the screen
assembly is damaged, stop using the monitor immediately.
5.4 Software Version Check
Some troubleshooting tasks may involve software version compatibility. For information about the configuration and
software version of your patient monitor, contact Mindray After-sales Service. To check the software version, do as
