⚠️Do not use this unit in areas where there in the presence of flammable gases such as anaesthetic agents or in an oxygen-rich environment.
⚠️Do not place the sensor on wounds, as this may cause additional injury.
7.2 MAINTENANCE
⚠️Before cleaning disconnect from the mains. Due to constant standby mode of the device do not clean terminals.
⚠️Do not, under any circumstances, immerse the unit or cable assemblies in liquid.
⚠️Do not use high-temperature sterilization processes (such as autoclaving). Do not use e-beam or gamma radiation sterilization.
⚠️Do not dispose of the device as unsorted municipal waste. Prepare it for recycling or separate waste collection in accordance with Directive 2002/96/EC on scrap electrical and electronic equipment (WEEE).
⚠️The AC/DC power supply must be connected to an easily accessible socket (the AC/DC power supply also serves for galvanic isolation).
7.3 FUNCTIONING OF THE DEVICE
⚠️Regularly inspect sensor and cable for any signs of damage. Do not use damaged sensor as the accuracy cannot be assured.
⚠️To prevent electric shock hazard due to current leakage, only use AC/DC power supplies which are compliant with the technical specifications of the device.
⚠️To prevent electric shock or damage to the device do not disassemble the unit. The device does not contain any parts which can be replaced or serviced by a user. If a defect occurs, consult your dealer or distributor.
⚠️Important information on electromagnetic compatibility (EMC). As the number of electronic devices such as computers and mobile phones in the room increases, medical devices can become sensitive to the electromagnetic influences of other devices. Electromagnetic interference can cause medical devices to malfunction, which can potentially lead to dangerous situations. Furthermore, medical devices must not interfere with other devices. The IEC/EN 60601-1-2 standard was introduced due to the necessity to establish electromagnetic compatibility (EMC) requirements for the prevention of dangerous situations in the use of medical devices. The standard defines the level of resistance to electromagnetic interference for medical devices. This medical device is compliant with the IEC/EN 60601-1-2 standard in terms of resistance to electromagnetic interference and electromagnetic emissions. Nevertheless, do not use mobile phones and similar devices which create strong electromagnetic fields in the vicinity of the device. This can cause the device to malfunction, which can potentially cause a dangerous situation.
⚠️Portable RF communications equipment including peripherals such as antenna cables and external antennas should be used no closer than 30 cm (12 inches) to any part of the MESI mTABLET SPO2 including cables specified by the manufacturer. Otherwise the degradation of the performance of this equipment could result.
⚠️Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in improper operation. If such use is necessary, this equipment should be observed to verify that they are operating normally.
⚠️Use of accessories, transducers and cables other than those specified or provided by the manufacturer of this equipment could result in increased electromagnetic emissions or decreased electromagnetic immunity of this equipment and result in improper operation.

Guidance and manufacturer’s declaration - electromagnetic immunity
MESI mTABLET SPO2 is intended for use in the electromagnetic environment specified below. The customer or the user of the above listed models should assure that they are used in such an environment.

Recommended separation distance d = 1.2√P d = 1.2√P 80 MHz - 800 MHz d = 2.3√P 800 MHz – 2.7 GHz Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the recommended separation distance in meters (m). Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey a should be less than the compliance level in each frequency range. (b) Interference may occur in the vicinity of equipment marked with the following symbol: |
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a) Field strengths from fixed transmitters such as base stations for radio (cellular/cordless) telephones, land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast, cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters an electromagnetic site survey should be considered. If the measured field strength in the location in which MESI mTABLET ABI is used, exceeds the applicable RF compliance level above, the above listed models should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the above listed models.
b) Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
c) The ISM (industrial, scientific and medical) bands between 0.15 MHz and 80 MHz are 6.765 MHz to 6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz. The amateur radio bands between 0.15 MHz and 80 MHz are 1.8 MHz to 2.0 MHz, 3.5 MHz to 4.0 MHz, 5.3 MHz to 5.4 MHz, 7 MHz to 7.3 MHz, 10.1 MHz to 10.15 MHz, 14 MHz to 14.2 MHz, 18.07 MHz to 18.17 MHz, 21.0 MHz to 21.4 MHz, 24.89 MHz to 24.99 MHz, 28.0 MHz to 29.7 MHz and 50.0 MHz to 54.0 MHz.
Recommended separation distances between portable and mobile RF communications equipment and the above listed models
MESI mTABLET SPO2 is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the above listed models can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the above listed models as recommended below, according to the maximum output power of the communication equipment.
Separation distance according to frequency of transmitter m
| Rated maximum output power of transmitter W | 150 kHz to 80 MHz d = 1.2√P | 80 MHz to 800 MHz d = 1.2√P | 800 MHz to 2.5 GHz d = 2.3 √P |
|---|---|---|---|
| 0.01 | 0.12 | 0.12 | 0.23 |
| 0.1 | 0.38 | 0.38 | 0.73 |
| 1 | 1.2 | 1.2 | 2.3 |
| 10 | 3.8 | 3.8 | 7.3 |
| 100 | 12 | 12 | 23 |
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be determined using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: The ISM (industrial, scientific and medical) bands between 150 kHz and 80 MHz are 6,765 MHz to 6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz.
NOTE 3: An additional factor of 10/3 has been incorporated into the formulae used in calculating the recommended separation distance for transmitters in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80 MHz to 2,5 GHz to decrease the likelihood that mobile/portable communications equipment could cause interference if it is inadvertently brought into patient areas.
NOTE 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
11.2 ESSENTIAL PERFORMANCE
Essential performance of MESI mTABLET SPO2 is measuring oxygen saturation of haemoglobin in arterial blood and pulse rate in beats per minute.
Due to the devices high sensitivity, intended use and operating modes the device is susceptible to EM interferences and should be used only in operating conditions specified in this instructions for use.
In case of errors in SpO₂ or HR measurement higher than defined in instructions for use due to EM interferences, the device presents an unacceptable risk and will warn the user of its inoperability.
