Safety and Regulatory Information
a
Field strengths from fixed transmitters, such as base station 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 CARESTREAM DRX-1 System is used exceeds the applicable RF
compliance level above, the CARESTREAM DRX-1 System should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the CARESTREAM
DRX-1 System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 v/m.
Recommended Separation Distance Between Portable and Mobile RF
Communications Equipment and the CARESTREAM DRX-1 System
The CARESTREAM DRX-1 System is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the CARESTREAM DRX-1 System
can help prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communication equipment (transmitters) and the CARESTREAM DRX-1 System as
recommended below, according to the maximum output of the communications equipment.

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 output
power rating of the transmitter in watts (W) according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, 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.
