19. Technical Data

Table 19-3. Guidance and Manufacturer’s Declaration – Electromagnetic Immunity

The HomeChoice/HomeChoice PRO APD System is intended for use in the electromagnetic environment specified below.

The user of the system should assure that it is used in such an environment.

Immunity Test

IEC 60601

Test Level

Compliance

Level Electromagnetic Environment – Guidance

Portable and mobile RF communications equipment should be used no closer to

any part of the

HomeChoice/HomeChoice PRO APD System, including cables,

than the recommended separation distance calculated from the equation

applicable to the frequency of the transmitter.

Recommended separation distance:

Conducted RF

IEC 61000-4-6

Radiated RF

IEC 61000-4-3

3Vrms 150 kHz

to 80 MHz

3V/m 80 MHz

to 2.5 GHz

3V/m

d = [3.5 / 3]

d = [3.5 / 3] 80 MHz to 800 MHz

d = [7 / 3] 800MHz to 2.5GHz

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

, should be less than the compliance level

in each frequency range.

Interference may occur in the vicinity of equipment marked with the

following symbol:

NOTES:

• At 80 MHz and 800 MHz, the higher frequency applies.

• 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 can not 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 system is used exceeds the applicable RF compliance level above, the system should be

observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as

reorienting or relocating the system.

b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
