Manufacturer’s declaration-electromagnetic immunity
The TD-3261G is intended for use in the electromagnetic environment (for home and professional healthcare) specified
below.
The customer or the user of the TD-3261G should assure that it is used in such and environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the TD-3261G including cables, than
the recommended separation distance
calculated from the equation applicable to the
frequency of the transmitter.
Recommended separation distance:
d = 1,2 √
P
d = 1,2 √
P
80MHz to 800 MHz
d = 2,3 √
P
800MHz to 2,7 GHz
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).
Interference may occur in the vicinity of
equipment marked with the following symbol:
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
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 TD-3261G is used exceeds the
applicable RF compliance level above, the TD-3261G should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating the TD-3261G.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
