Immunity Test
IEC 60601 Test Level Compliance
This device is intended for use in the electromagnetic environment specified below.
The customer and/or user of this device should ensure that it is used in such an environment.
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.

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 reorienting or relocating the device.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3] V/m.
NOTE: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from struc-
tures, objects, and people.
Table 4: Recommended Separation Distances
The following table details the recommended separation distances between portable and mobile RF communications equipment and this device.
This device is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. Users of this device can help
prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communication equipment (transmit-
ters) and the device as recommended below, according to maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (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: At 80 MHz and 800MHz, the separation distance for the higher frequency range applies.
NOTE: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects, and people.
