z
When you disassemble/reassemble a parameter module, a patient leakage current test must be performed before it is used again for monitoring.
z
The equipment must be connected to a properly installed power outlet with protective earth contacts only. If the installation does not provide for a protective earth conductor, disconnect it from the power line and operate it on battery power, if possible.
z
Dispose of the package material, observing the applicable waste control regulations and keeping it out of children’s reach.
1.1.3 Cautions
CAUTION z
Make sure that no electromagnetic radiation interferes with the performance of the equipment when preparing to carry out performance tests. Mobile phone, X-ray equipment or MRI devices are a possible source of interference as they may emit higher levels of electromagnetic radiation.
z
Before connecting the equipment to the power line, check that the voltage and frequency ratings of the power line are the same as those indicated on the equipment’s label or in this manual.
z
Protect the equipment from damage caused by drop, impact, strong vibration or other mechanical force during servicing.

2 Theory of Operation 2.1 Introduction This patient monitor is designed to monitor a fixed set of physiological parameters including ECG, heart rate (HR), respiration (Resp), temperature (Temp), SpO2, pulse rate (PR), non-invasive blood pressure (NIBP), invasive blood pressure (IBP), cardiac output (C.O.), carbon dioxide (CO2), oxygen (O2), anesthetic gas (AG), impedance cardiograph (ICG), bispectral index (BIS), respiration mechanics (RM), continuous cardiac output (PiCCO), central venous oxygen saturation (ScvO2), electroencephalograph (EEG), and neuromuscular transmission (NMT). The patient monitor also:
Provides audible and visual alarm indications in case of patient or equipment problems.
Enables displaying, reviewing, storing and transferring of real-time data.
Incorporates multiple input devices such as buttons, knob, touchscreen, keyboard and mouse.
Interfaces a clinical information system or central monitoring system.
Enables program upgrade over the network.
Integrates the information of other devices, which include but are not restricted to anesthesia machine and ventilator.

2.2 System Connections 2.2.1 Mounting the Patient Monitor The patient monitor can be mounted on a wall bracket or on a trolley support. The wall bracket or trolley support can be ordered optionally. Each type of mounting bracket is delivered with a complete set of mounting hardware and instructions. Refer to the documentation delivered with the mounting hardware for instructions on assembling mounts.
CAUTION z
Not using screw and bracket specified by Mindray may cause the screw to touch the internal battery and lead to monitor damage (the proper screw depth should be between 6.5mm and 7.5mm). Take out the rubber stoppers in the two screw holes of the base when installing the tray.
z
The mounting bracket should be installed by our qualified service personnel, or engineers who have adequate knowledge on it.
z
If other mounting solution is used, the installation personnel and the customer should verify if it can be safely used on the patient monitor, and the customer assume the responsibility for any risk resulting from that.

2.3.1 Input System Button board The button board, located at the lower part of the monitor’s front panel, contains 6 keys and provides connections for the following components to the main board:
Knob
Power switch & LED board
Touchscreen control board
Alarm LED board
Inverter
The following diagram shows the button board connections.
Knob The knob can be pressed, or rotated both clockwise and counter-clockwise. It is connected with the button board.
