Portable and mobile RF communications equipment can affect the E2
Microprobe Laser and Endoscopy System.
Recommended separation distances between portable and mobile RF communications
equipment and the E2 Microprobe Laser and Endoscopy System
The E2 Microprobe Laser and Endoscopy System is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of the E2
Microprobe Laser and Endoscopy System can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the E2 Microprobe Laser and Endoscopy System as recommended below,
according to the maximum output power of the communications equipment.

Separation distance according to frequency of transmitter m
150kHz to 80MHz
d = [1.667]¥P
80MHz to 800MHz
d = [1.667]¥P
800MHz to 2.5GHz
d = [2.333]¥P
0.01 d = 0.167 d = 0.167 d = 0.233
0.1 d = 0.527 d = 0.527 d = 0.738
1 d = 1.667 d = 1.667 d = 2.333
10 d = 5.271 d = 5.271 d = 7.377
100 d = 16.67 d = 16.67 d = 23.333
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 80MHz 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 the structures, objects and people.
