Chapter 1 Intended Use and Safety Guidance
1.1 Intended Use/Indications for Use
The monitor is intended to be used by qualified physicians or personnel professionally trained
and it is for monitoring adults, pediatrics and neonates in hospital environments.
This monitor is used to monitor vital signals for patients and is suitable for use in hospital
environments including out-patient department, wards and NICU.
Monitored parameters include: NIBP, SpO

, pulse rate, Quick TEMP/Infrared TEMP.
1.2 Safety Guidance
1.2.1 Environment
Follow the instructions below to ensure completely safe electrical installation. The environment
where the monitor will be used should be reasonably free from vibration, dust, corrosive or
explosive gases, extremes of temperature, humidity, and so on. For a cabinet mounted installation,
allow sufficient room at the front for operation and sufficient room at the rear for servicing with
the cabinet access door open.
The monitor operates within specifications at ambient temperatures between 0 C ~+40 C.
Ambient temperatures that exceed these limits could affect the accuracy of the instrument and
cause damage to the modules and circuits. Allow at least 2 inches (5 cm) clearance around the
instrument for proper air circulation.
1.2.2 Power Source Requirements
Refer to Appendix
A
.
1.2.3 Grounding the Monitor
To protect the patient and hospital personnel, the cabinet of the monitor must be grounded.
Accordingly, the monitor is equipped with a 3-wire cable which grounds the instrument to the
power line ground (protective earth) when plugged into an appropriate 3-wire receptacle. If a
3-wire receptacle is not available, consult the hospital electrician.
Connect the grounding wire to the equipotential grounding terminal on the mains system. If it is
not evident from the instrument specifications whether a particular instrument combination is
hazardous or not, for example due to summation of leakage currents, the user should consult the
manufacturers concerned or an expert in the field, to ensure that the necessary safety of all
instruments concerned will not be impaired by the proposed combination.
1.2.4 Equipotential Grounding
Protection class 1 instruments are already included in the protective grounding (protective earth)
system of the room by way of grounding contacts in the power plug. For internal examinations on
the heart or the brain, the Monitor must have a separate connection to the equipotential grounding
system. One end of the equipotential grounding cable (potential equalization conductor) is
connected to the equipotential grounding terminal on the rear panel of the instrument and the
other end to one point of the equipotential grounding system. The equipotential grounding system
