Guidance and manufacturer’s declaration – electromagnetic immunity
The SmartLite
®
Max Light is intended for use in the electromagnetic environment specified below.
The customer or user of the light should assure that it is used in such an environment.

Portable and mobile RF communications equipment should be used no closer
to any part of the SmartLite

recommended separation distance calculated from the equation applicable to
the frequency of the transmitter.

, should be less than the compliance level in each
frequency range.

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.
NOTE 3: UT is the a.c. mains voltage prior to application of the test level.
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 SmartLite
®
Max Light is used exceeds the applicable RF compliance level above, the SmartLite
®
Max Light should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the SmartLite
®
Max Light.
b
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the SmartLite

Max Light
The SmartLite
®
Max Light is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or user of the light can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the SmartLite
®
Max Light as recommended below, according to the 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 1: At 80 MHz and 800 MHz, 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.
