Caution: The monitor does not contain any user-serviceable parts. The repair of the instrument must be
conducted by technical personnel authorized by the manufacturer.
2.3 Important Notes for Safety
• Patient Number
The monitor can only be applied to one patient at one time.
• Interference
Do not use a mobile phone in the vicinity of the monitor. High level of electromagnetic radiation emitted from
such devices may result in strong interference with the monitor performance.
• Protection against ingress of liquid
To avoid electric shock or device malfunction, liquids must not be allowed to enter the device. If liquids have
entered the device, take it out of service and have it checked by a service technician before it is used again.
• Accuracy
If the accuracy of any value displayed on the monitor or printed on a printout paper is questionable, determine
the patient’s vital signs by alternative means. Verify that the equipment is working correctly.
• Alarm
• Do not rely exclusively on the audible alarm system for patient monitoring. Adjustment of alarm volume to a
low level or off during patient monitoring may result in a hazard to the patient. Remember that the most
reliable method of patient monitoring combines close personal surveillance and correct operation of
monitor.
• The functions of the alarm system for monitoring the patient must be verified at regular intervals.
• Before Use
• Before putting the system into operation, please visually inspect all connecting cables for signs of damage.
Damaged cables and connectors must be replaced immediately.
• Before using the system, the operator must verify that it is in correct working order and operating condition.
• Periodically, and whenever the integrity of the product is in doubt, test all functions.
• Cables
Route all cables away from patient’s throat to avoid possible strangulation.
• Disposal of package
When disposing of the packaging material, please observe the applicable waste control
regulations and keep packaging material out of children’s reach.
• Leakage current test
When interfacing with other equipment, a test for leakage current must be performed by qualified biomedical
engineering personnel before using with patients.
• Battery
The device is equipped with a battery. The battery discharges even when the device is not in use. Store the
device with a fully charged battery and take out the battery, so that the service life of the battery will not be
shortened.
• Disposal of accessories and device
• Disposable accessories are intended for single use only. They should not be reused as performance could
degrade or contamination could occur.
