SAFETY INFORMATION
Guidance and manufacturer’s declaration – electromagnetic immunity
The
DR-17G and DR-22G is intended for use in the electromagnetic environment specified below. The
customer or the user of the DR-17G and DR-22G should assure that it is used in such an environment.
Not Life-supporting Medical Equipment.

Portable and mobile RF
communications equipment should
be used no closer to any part of the
DR-17G and DR-22G, 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
800MHz
d = 2.3 √ P, 800MHz to 2.5GHz
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
meters (m).
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
b. Interference may occur in the
vicinity of equipment marked with
the following symbol
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.
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
DR-17G and DR-22G is used exceeds the applicable RF compliance level above, the DR-17G and DR-22G
should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as reorienting or relocating the DR-17G and DR-22G.
