DRSplus – Operating Manual
drsplus is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of drsplus can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and drsplus as recommended below, according to the maximum output power of the
communications equipment.
Do not use portable radio frequency (RF) communication devices (including peripheral devices such
as antenna cables and external antennas) at distances of less than 30 cm from any component of the
drsplus, including manufacturer recommended cables. Failure to observe this precaution may
compromise the performance of the device

Separation distance according to frequency of transmitter
150 kHz to 80 MHz
d = 1.17√P
80 MHz to 800 MHz
d = 1.17√P
800MHz to 2.5 GHz
d = 1.17√P
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 power rating of the transmitter in (W) according to the
transmitter manufacturer.
NOTE 1: At 80MHz and 800MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflections from structures, objects and people.
