WARNING
WARNING
Use of any accessories and cables other than those specified in
Planmeca Intra X-ray unit’s documentation, with exception of cables
sold by Planmeca as replacement parts for internal components, may
result in increased emission or decreased immunity of the X-ray unit.
Planmeca Intra X-ray unit should not be used adjacent to or stacked
with other equipment. If adjacent or stacked use is necessary, the
Planmeca Intra X-ray unit should be observed to verify normal
operation in configuration which it will be used.
Guidance and manufacturer’s declaration - electromagnetic emissions
Planmeca Intra X-ray unit is intended for use in the electromagnetic environment specified

Interference may occur in the vicinity of

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 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 Planmeca Intra X-ray unit is used exceeds the
applicable RF compliance level above, Planmeca Intra X-ray unit should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating Planmeca Intra X-ray unit.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
