RECOMMENDED ISOLATION DISTANCE BETWEEN PORTABLE AND MOBILE RADIO FREQUENCY
COMMUNICATION EQUIPMENT AND KD-901E high voltage potential therapeutic apparatus
Electric wheelchairs are expected to be used in an electromagnet ic environment where RF radiation di sturbance is control led. Depending on the maximum amount
communication equipment and the power output, the purchaser or user can maintain portable and mobile radio f requency communication through the followin
recommendat ions, the min imum distance between the device and the electric whee1chair to prevent electromagnetic interference.

For the transmitter* s maximum rated output power not listed in the table above, it is recommended
that the isolation distance D, in meters (m) , be determined by the formula in the corresponding
transmitter frequency column, here P is the maximum rated output power of the transmitter supplied
by the transmitter manufacturer, in Watts (W).
Note 1: At 80mh and 800mhz frequency points, the formula for the higher frequency band is used.
Note 2 : These guidel ines may not be appropriate in all cases. Electromagnetic propagation is affected
by the absorption and reflection of buiIdings, objects and the human body.
