Portable and mobile radios should not
be used at a distance from the JMA-
Optic system, including lines, less than the
recommended separation distance, which
is calculated according to the equation
applicable to the transmitting frequency.

manufacturer‘s specifications and the recom-
mended separation distance in meters (m).

The JMA-Optic system is intended for operation in the electromagnetic environment specified
below. The customer or the user of the JMA-Optic system should ensure that it is used
in such an environment.
Guidelines and manufacturer‘s declaration - Electromagnetic immunity
a The field strength of stationary transmitters, such as base stations of radio telephones and land
mobile radios, amateur radio stations, AM and FM radio and television transmitters, cannot
theoretically be predicted. In order to determine the electromagnetic environment with respect to
stationary transmitters a study of the electromagnetic phenomena of the site should be considered.
If the determined field strength at the site of the JMA-Optic system exceeds the above compli-
ance levels, the JMA-Optic system should be observed for field strength to verify that it is
operating as intended. Demonstrate that it is functioning as intended. If unusual performance
characteristics are observed additional measures may be required, such as changing the orientation
or location of the JMA-Optic system different location of the JMA-Optic system.
b Over the frequency range from 150 kHz to 80 MHz, the field strength should be less than 3 V/m
NOTE 1 At 80 MHz and 800 MHz, the higher value applies.
NOTE 2 These guidelines may not be applicable in all cases. The propagation of electromagnetic
quantities is affected by absorption and reflection from buildings, objects, and people.
