RF emissions CISPR 11 Group 1 The TG250/TG380 uses RF energy only for its internal func-
tion. Therefore, its RF emissions are very low and are not
likely to cause any interference in nearby electronic equip-
ment.

Recommended separation distance between portable and mobile RF communications equipment and
the TG250/TG380
The TG250/TG380 is intended for use in an electromagnetic environment in which radiated RF distur-
bances are controlled. The customer or the user of the TG250/TG380 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the TG250/TG380 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 trans-
mitter, where P

a Field strengths from xed 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 pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to xed RF transmit-
ters, an electromagnetic site survey should be considered. If the measured eld strength in the location
in which the TG250/TG380 is used exceeds the applicable RF compliance level above, the TG250/
TG380 should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the TG250/TG380.
b Over the frequency range 150 kHz to 80 MHz, eld strengths should be les than 3 V/m.
