Electromagnetic emissions and immunity The device is approved according to EMC safety standard IEC 60601-1-2. It is designed to be used in typical domestic environments. Table 1 Guidance and manufacturer's declaration - electromagnetic emissions - for all ME equipment and ME systems Guidance and manufacturer's declaration - electromagnetic emissions The device is intended for use in the electromagnetic environment specified below. The customer or the user of the device should assure that it is used in such an environment. Emissions test Com­pli­ ance Electromagnetic environment guidance RF emissions Group 1 CISPR 11 RF emissions Class B CISPR 11 The DL8740 uses RF energy only for its internal function. Therefore, its RF emissions are very low and are not likely to cause any interference in nearby electronic equipment.

IMMUNITY test -- IEC 60601 Compliance TEST LEVEL level Conducted RF 3 Vrms IEC 610004-6 150 kHz to 80 MHz 3 Vrms Radiated RF 3 V/m 3 V/m IEC 610004-3 80 MHz to 2.5 GHz Electromagnetic environment - guidance Portable and mobile RF communications equipment should be used no closer to any part of the device, including cables, than the recommended separation distance calculated from the equation applicable to the frequency of the transmitter. Recommended separation distance: d = 1.2 √P d = 1.2 √P 80 MHz to 800MHz d = 2.3 √P 800 MHz to 2.5 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 metres (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 and 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 the device is used exceeds the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device. (b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m. Table 6 Recommended separation distances between portable and mobile RF communications equipment and the ME equipment or ME system - for ME equipment and ME systems that are not life supporting Recommended separation distances between portable and mobile RF communications equipment and the device. The device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the device as recommended below, according to the maximum output power of the communications 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 0.01 0.12 80 MHz to 800 MHz d = 1.2 √ P 0.12 800 MHz to 2.5 GHz d = 2.3 0.23 0.1 0.37 0.37 0.74 1 1.2 1.2 2.3 10 3.7 3.7 7.4 100 12 12 23 For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (m) can be estimated 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 80MHz and 800MHz, the separation distance for 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. Explanation of symbols The warning signs and symbols are essential to ensure that you use this product safely and correctly and to protect you and others from injury. Below you find the meaning of the warning signs and symbols on the label and in the user manual. Read the user manual before you use the device.
