Field strengths from xed RF transmiers, as determined by an electromagnec site
survey,ashould be less than the compliance level in each frequency range.b
Interference may occur in the vicinity of equipment marked with the following sym-
bol:
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply to all situaons. Electromagnec propagaons is aected by absorpon and reecons from struc-
tures, objects and people.
a Field strengths from xed transmiers, such as base staons for radio (cellular/cordless) telephones and land mobile radios, amateur ra-
dio, AM and FM radio broadcast and TV broadcast cannot be predicted theorecally with accuracy. To assess the electromagnec environ-
ment due to xed RF
transmiers, an electromagnec site survey should be considered. if the measured eld strength in the locaon in which the model SC-
2004-OC/SC-2004FC-OC/SC-2008-OC is used exceeds the applicable RF compliance level above, the model SC-2004-OC/SC-2004FC-OC/SC-
2008-OC should be observed to verify normal operaon. If abnormal performance is observed, addional measures may be necessary,
such as re-orienng or relocang the model SC-2004-OC/SC-2004FC-OC/SC-2008-OC.
bOver the frequency range 150 kHZ to 80 MHz, eld strengths should be less than 3 V/m.

Group 1 The model SC-2004-OC/SC-2004FC-OC/SC-2008-OC uses RF energy only for its internal
funcons. Therefore, its RF emissions are very low and are not likely to cause any inter-
ference in nearby electronic equipment.

The SC-2004-OC/SC-2004FC-OC/SC-2008-OC are intended for use in an electromagnec environment in which radiated RF disturbances are
controlled. The customer of user of the SC-2004-OC/SC-2004FC-OC/SC-2008-OC can help prevent electromagnec interference by maintain-
ing a minimum distance between portable and mobile RF communicaons equipment (transmiers) and the SC-2004-OC/SC-2004FC-OC/SC-
2008-OC as recommended below, according to the maximum output power of the communicaons equipment.

Note 1: At 80 MHz, the separaon distance for the higher frequency range applies.
Note 2: These guidelines may not apply in all situaons. Electromagnec propagaon is aected by absorpon and reecon from struc-
