Guidance and manufacturer’s declaration – ELECTROMAGNETIC IMMUNITY –
FOR EQUIPMENT AND SYSTEMS THAT ARE NOT LIFE-SUPPORTING
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.

Portable and mobile RF communications equipment should not be used near any part of the device,
including cables, except when the recommended separation distance is respected, calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance

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 surveya, should be
less than the compliance level in each frequency rangeb.
Interference may occur in the vicinity of equipment marked with the symbol above:
Note:
(1) At 80 MHz and 800 MHz, the higher frequency range applies.
(2) Electromagnetic propagation is affected by absorption and reflection from structures,
objects and people.
a) Field strengths from fixed RF 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 RESTART is used exceeds the applicable RF compliance level above,
RESTART should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating RESTART.
b) Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
