8.3.3 Table 204: Guidance and manufacturer's
declaration – electromagnetic immunity
The massage unit has been designed for use in the electromagnetic sur-
roundings listed below. The operator of this equipment must ensure that it is
only used in one of these surroundings.
Compliance Electromagnetic environment – Guidance
level
Portable and mobile wireless equipment is not to be used
closer to the massage unit, including the lines, than the
recommended safety distance, which has been calculated
for the transmitting frequency using a suitable equation.
Recommended safety distance:
3 Vrms
3 V/m
Where P is the transmitter's maximum output power (rated
power) in Watts (W) in accordance with the details supplied
by the manufacturer of the transmitter and the recommend-
ed safety distance is given in metres (m).
The field strength of the stationary radio transmitter is less
than the agreed level for all frequencies
an on-site test
The following symbol must be used in the areas surround-
ing the equipment to indicate that interference is possible.
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.
a Field strength from fixed transmitters, such as base stations for radio (cel-
lular/cordless) telephones and land mobile radios, amateur radio, AM and
FM radio 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 massaging unit is used exceeds the
applicable RF compliance level above, the unit should be observed to veri-
fy normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the unit.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 3 V/m.
