WARNING
Before putting the system into operation, the operator must verify that the equipment,
connecting cables and accessories are in correct working order and operating condition.
Make sure the synchronous input system is applied to this equipment and the input signal is
correct if necessary.
To avoid risk of electric shock, this equipment must only be connected to a supply mains with
protective earth. If the installation does not provide for a protective earth conductor,
disconnect it from the power line and operate it on smart lithium-ion batteries.
Ensure that the equipment is supplied with continuous electric power during work. Sudden
power failure leads to the loss of patient data.
Use and store the equipment in specified environmental condition. The equipment and
accessories may not meet the performance specification due to aging, stored or used outside
the specified temperature and humidity range.
This equipment is used for single patient at a time.
Medical electrical equipment which does not incorporate defibrillator protection should be
disconnected during defibrillation.
Do not defibrillate a patient who lies on the wet ground.
Do not touch the patient and live parts simultaneously.
Do not touch the patient when connecting the peripheral equipment via the I/O signal ports to
prevent patient leakage current from exceeding the requirements specified by the standard.
1-2
Page 11
Do not rely exclusively on the audible alarm system for patient monitoring. Adjustment of
alarm volume to a low level or off may result in a hazard to the patient. Remember that alarm
settings should be customized according to different patient situations and always keeping
the patient under close surveillance is the most reliable way for safe patient monitoring.
Do not perform any functional check if the equipment is connected with a patient; otherwise
the patient might be shocked.
Remain attentive to the patient during applying therapy. Delay in delivering a shock may
result in a rhythm that was analyzed as shockable converting spontaneously to non-shockable
and could result in inappropriate delivery of a shock.
For the treatment of patients with implantable pacemakers, place therapy pads or paddles
away from internal pacemaker generator if possible to help prevent damage to the pacemaker.
To avoid inadvertent disconnection, route all cables in a way to prevent a stumbling hazard.
Wrap and secure excess cabling to reduce risk of entanglement or strangulation by patients or
personnel.
Do not touch device connectors, recorder print head, battery connector or other live
equipment if in contact with the patient; otherwise patient injury may result.
To ensure patient safety, use only parts and accessories specified in this manual.
Package material may contaminate the environment. Properly dispose of the package material
according to applicable waste control regulations and keep it out of children’s reach.
1.1.3 Cautions
CAUTION
Use of Manual Therapy security password requires the clinician to know and remember the
password. Failure to enter correct password will prevent the delivery of manual defibrillation,
synchronized cardioversion and pacing therapy.
At the end of its service life, the equipment, as well as its accessories, must be disposed of in
compliance with the guidelines regulating the disposal of such products to avoid
contaminating the environment.
Magnetic and electrical fields are capable of interfering with the proper performance of the
equipment. For this reason make sure that all external devices operated in the vicinity of the
equipment comply with the relevant EMC requirements. Mobile phones, X-ray equipment or
MRI devices are a possible source of interference as they may emit higher levels of

2.3.3 Signal Sequence of Power-On/Off
The power-on/off action is triggered by the naviagation knbo on the keypad board of the front housing.
The power-on/off process is controlled by the power management processor as follows:
Power-on process: When you rotate the mode switch on the front panel of the defibrillator/monitor to a
mode other than "Off", the PCON signal value is changed from 1 to 0 to awake the MCU. The MCU
immediately outputs the ENABLE control signal to the TPS2490 enabling the VBUS. Then, the MCU enables
the RUN signal control of the dual-line DC-DC module to output 5 V (VBB) and 12 V signals.
Power-off process: When your rotate the mode switch to "Off", the PCON signal value is changed from 0 to
1, and the MCU outputs the ENABLE=0 and RUN=0 signals to shut down the VBUS and the DC-DC module.
2.4 Front Housing Assembly
The front housing assembly consists of display assembly, a keypad board, a speaker, a microphone, a
Mode Select knob, a navigation knob, an alarm lamp board, a front housing and front housing sheet metal,
