8.2 Preparations for Disassembly
Before disassembling the monitor, make the following preparations:
Stop monitoring the patient, turn off the monitor, and disconnect all the accessories and peripheral devices.
WARNING
Before disassembly, be sure to eliminate static electricity. When removing some parts with the
electrostatic sensitive marks, wear protective devices such as antistatic wristband or gloves to avoid
damaging the parts.
Properly connect and route the cables and wires when reassembling the monitor to avoid short circuits.
Use specified screws to reassemble the monitor. If unfit screws are tightened by force, the monitor may
be damaged and the screws or part may fall off during use, causing unpredictable equipment damage or
human injury.
Follow the correct sequence to disassemble the monitor.
Place the removed parts by category to facilitate reassembly. Do not drop, contaminate or lose them.
To reassemble the monitor, first install the assemblies, and then the main unit. Carefully route the cables.
Make sure that the waterproof materials are properly applied during reassembly.
