1.6. Reducing EMI
To reduce possible problems caused by electromagnetic interference, we recommend the following: Use only MIPM-approved accessories (See Section 8). Use of other accessories may result in increased emissions or decreased immunity of M3 the Tesla .
Ensure that other products used in areas where patient monitoring and/or life-support are used comply with legal emissions standards. If the products are used inside the MRI room, make sure that the products are labeled MRI conditional or MRI Safe. M3 Try to maximize the distance between Tesla and other Wifi electro medical devices. Strictly limit exposure and access to portable radio-frequency sources (e.g., cellular phones and radio transmitters). Be aware that portable phones may periodically transmit even when in standby mode. Maintain good cable management. Do not route cables over electrical equipment. Do not intertwine cables. Ensure all electrical maintenance is performed by qualified personnel. The medical electrical equipment needs special precautions regarding EMC and needs to be installed according to EMC information. M3 RF communications equipment can affect the Tesla . The data is transmitted via WLAN between master and remote monitor. The channel 2 (2417 MHz; 100 mW) is set. The data is transmitted via MiWi between master monitor and both sensors (wireless ECG Sensor and wireless Pulse Oximetry Sensor). There are sixteen channel frequencies in the 2.4 GHz band:
The transmitter is a direct conversion architecture with a 0 dBm maximum output (typical) and 36 dB power control range.

1.7. Electrical Safety 1.7.1. Electrostatic discharge (ESD) information Warning: Electronic components and semiconductors can be destroyed by electrostatic discharge (ESD). In particular, MOS components can be damaged from direct or indirect discharges. Damage caused by ESD is sometimes not immediately identifiable and malfunctions can even occur after a longer period of operation. Exceeding and / or repeating the test level attained in guidance & manufacturer's declaration on EMC may permanently damage the device and / or cause serious malfunctions as loss of communication and system reboot. Caution:
Connector panel symbol All panel connector and communication ports are sensitive to electrostatic discharges; it is necessary to take precautions before touching connectors (pins or shield), connecting or disconnecting the associated cables. Touching communication ports without taking ESD precautions may result in potential fatal error and ESD protection failure. Points (e.g. screws) and surfaces that are only accessible for maintenance also require precautions. Points (e.g. battery contacts for battery replacement) and surfaces that are accessible only by intervention service users also require precautions.
1.7.2. ESD precautions to be taken The following instructions related to electrostatic sensitive components (ESD standards) must be observed: floor coatings made from wood, tiles and concrete, with relative humidity at least 40%. If it is not possible to guarantee this environment, additional precautions must be taken, such as: use of anti-static equipment, preliminary user discharge and wearing of anti-static clothes. The best precaution is the preliminary user discharge on a metal ground such as a metal rail, metal M3 pole or metal part located at the rear of Tesla . M3 For maintenance operation performed on Tesla , the device must be placed on a conductive working surface and the operator must wear a special ESD conductive wristband.

The MRI (MRI conditional) Patient Monitor Tesla fulfills the following standards referring to creation and inhibition of electromagnetic interferences: EN55011 and IEC60601-1-2. M3
Tesla has been tested in accordance with the electromagnetic compatibility standards applicable to medical devices. Its immunity is designed to ensure correct operation. Limitation of the emitted radiation avoids undesirable interference with other equipment. M3 Tesla is classified as a Class B device according to CISPR 11 emitted radiation and should not be used outside the hospital environment. If used outside the hospital environment, this equipment might not offer adequate protection to radio-frequency communication services. The user might be required to take mitigation measures, such as relocating or re-orienting the equipment. Use of accessories and cables other than those recommended by MIPM, could result in increased M3 emissions and / or decreased immunity of the Tesla system. M3
If Tesla is placed near devices such as HF surgical equipment, X-ray equipment, cell phones, DECT phones or wireless access points, portable RFID reader, large scale RFID reader and RFID Tags, it is M3 essential to observe a minimum distance between the Tesla and this equipment (refer to 'Table 4 Recommended separation distances between portable and mobile RF communication equipment and M3 Tesla ). M3 If Tesla causes harmful interference or if it is itself disrupted, the user is encouraged to try to correct the interference by one of the following actions:
M3
Reorient or relocate the Tesla or patient or disruptive equipment. Change the routing of cables. Separate power cables from the communication cables / signals. M3 Connect Tesla mains plug on protected / backed-up / filtered supply or directly on UPS circuit (uninterruptible power supply). Be careful with ground / earth loops formed by communication cables and / or power circuits: use class II powered systems or insulated bridges to break loops. M3 Maintain earth potential at the same level between Tesla circuit and the circuit of the remote equipment. M3 Increase the separation between the Tesla and patient or disruptive equipment. M3 Connect the Tesla into an outlet on a circuit different from that to which the patient or disruptive equipment is connected. In any case, whatever the context, the user should conduct interoperability testing in a real situation to find the right setup and good location. M3 The Tesla shall not be used adjacent to or stacked directly with other devices. If an M3 operation of the Tesla stacked directly with or used adjacent to other devices is M3 required, the Tesla should be observed to verify its proper operation used in this arrangement. M3 The Tesla may be interfered with by other equipment, even if that other equipment complies with CISPR EMISSION requirements.
