1.2.1 Warnings

WARNING

All installation operations, expansions, changes, modifications and repairs of this product are conducted by Mindray authorized personnel.

There is high voltage inside the equipment. Never disassemble the equipment before it is disconnected from the AC power source or the battery.

When you disassemble/reassemble a parameter module, a patient leakage current test must be performed before it is used again for monitoring.

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.

Disposal of the packaging material should observe the applicable waste control regulations and keeping it out of children’s reach.

1.2.2 Cautions

CAUTION

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.

Before connecting the receiver to the power line, check that the voltage and frequency ratings of the power line are the same as those indicated on the unit’s label or in this manual.

Protect the equipment from damage caused by drop, impact, strong vibration or other mechanical force during servicing.

1.2.3 Notes

NOTE

Refer to operator’s manual for detailed operation and other information.

2.5 Rear Housing Assembly

Power management and

interface board AC/DC power module

SpO2 board

Battery compartment

NIBP module

Rear housing assembly consists of power module (AC/DC), power management and interface board (including SpO2 isolation power), battery compartment, NIBP module, and SpO2 board.

AC/DC Power Module

The AC/DC power board transforms the input AC into DC power, and is the power source for all voltages in the equipment.

Power management and interface board

The power management interface board provides the following functions:

Charge and discharge of battery and charge detection;

DC/DC conversion: outputs 12V and 5V DC power;

Control over power On/Off key and AC, BAT indicator;

Communication transmission among parameter modules;

Providing isolation power for the SpO2 module; and,

Providing external connectors, filter and protection for these connectors.

2-4

NIBP Module

The NIBP module consists of blood pressure measurement board and pump and valve assembly, providing measurement acquisition of blood pressure data. The main functions of the NIBP module are:

NIBP measurement; and,

Data exchange with the main board through the serial ports.

SpO2 board

The SpO2 board collects SpO2 signals, processes SpO2 algorithm and sends measurement results to the main board. The power management interface board provides isolation power for it.

2.6 External Module

An external Temperature module can be mounted on the monitor.

The independently developed Mindray Temperature module consists of an isolation power board, Temperature measurement board, and probes. The Temperature measurement board collects Temperature signals, processes algorithm and sends measurement results to the main board.
