If the fixed transmitting airport is strong, such as the base station of wireless (cellular
/ cordless) telephone and ground mobile radio, amateur radio, am (amplitude modu-
lation) and FM (frequency modulation) radio broadcast and television broadcast, and
the field strength of the place where NPL001
、
NPL002
、
NPL003 electric
wheelchairs are located is higher than the RF coincidence level of the above applica-
tion, then the electric wheelchair should be observed to verify It can operate normal-
ly. If abnormal performance is observed, supplementary measures may be neces-
sary, such as reorientation or repositioning of the electric wheelchair.
D09/ D09B/ D09C/ D09D/ D09E Power Wheelchair is expected to be used in an elec-
tromagnetic environment where radiated RF disturbances are controlled. According
to the maximum output power of communication equipment, the buyer or user of
electric wheelchair can prevent electromagnetic interference by maintaining the mini-
mum distance between portable and mobile RF communication equipment (transmit-
ter) and electric wheelchair.
For the rated maximum output power of the transmitter not listed in the above table, the
recommended isolation distance D, in meters (m), can be determined by the formula in
the corresponding transmitter frequency column, where P is the maximum output rated
power of the transmitter provided by the transmitter manufacturer, in watt (W).
Note 1: at 80 MHz and 800 MHz frequencies, the formula for the higher frequency
range is used.
Note 2: these guidelines may not be suitable for all cases where electromagnetic propa-
gation is affected by absorption and reflection of buildings, objects and human bodies.
Recommended separation distance between portable and mobile RF communication
equipment and electric wheelchair.
The field strength should be less than 3 V / m in the whole frequency range of 150
kHz to 80 MHz.
