Recommended separation distances between portable and mobile RF communication equipment and the
device
The MYOPIA EXPERT 700 device is intended for use in an electromagnetic environment in which radiated
RF interferences are controlled. The customer or the user of the device can help prevent electromagnetic
interference by keeping a minimum distance between portable and mobile RF communication equipment
(transmitters) and the device as recommended below, according to the maximum output power of the
communication equipment.
Rated maximum output
of transmitter (W)
Separation distance according to transmitter frequency (m)
150kHz to 80MHz 80MHz to 800MHz 800MHz to 2GHz

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
(2) These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.
