Fora D40 DUO ultima Owner's Manual page 25

The FORA D40 is intended for use in the electromagnetic environment (for home healthcare and professional healthcare) specified below.
The customer or the user of the FORA D40 should assure that it is used in the environment specified below.

80 % AM at 1 kHz
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply to 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 FORA D40 is used exceeds the applicable RF compliance level above, the FORA D40 should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the
FORA D40.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
The FORA D40 is intended for use in an electromagnetic environment (for home healthcare and professional healthcare) in which radiated
RF disturbances are controlled. The customer or the user of the FORA D40 can help prevent electromagnetic interference by maintaining
a minimum distance between the portable and mobile RF communications equipment (transmitters) and the FORA D40 as recommended
below, depending on 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 transmitter, where p is the maximum output power rating of the transmitter in watts (W)
depending on the transmitter manufacturer.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These guidelines may not apply to all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
