WARNING: Portable RF equipment
(including peripherals such as antenna
cables and external antennas) should be
used no closer than 30 cm (12 inches)
to any part of the System 7 Dual Trigger
Rotary Handpiece (REF 7205-000-
000), including cables specified by the
manufacturer. Otherwise, degradation of
the performance of this equipment could
result.
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,a
should be less than the compliance level in each
frequency range.bInterference may occur in the
vicinity of equipment marked with the following
symbol:
(Non-ionizing electromagnetic radiation)
NOTE 1: At 80 MHz and 800MHz 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.
aField 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 System 7 Dual Trigger Rotary Handpiece
(REF 7205-000-000) is used exceeds the applicable RF compliance level above, the System 7 Dual Trigger Rotary Handpiece (REF 7205-000-000) should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
System 7 Dual Trigger Rotary Handpiece (REF 7205-000-000).
bOver the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Rotary Handpiece (REF 7205-000-000) as recommended below, according to the maximum output power of the
equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance din meters (m) can be estimated using the
equation applicable to the frequency of the transmitter, where Pis the maximum output power rating of the transmitter in watts (W) according to the
transmitter manufacturer.
NOTE 1: At 80 MHz and 800MHz, the separation distance for 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.
