Electromagnetic Interference (Emi) - Heartway Medical Products S23K User Manual


Inspections prior to using your power scooter:
1. If equipped with pneumatic tires, please check for proper tire inflations.
2. Please check all electrical connections and make sure they are tight and not corroded.
3. Please check all harness connections and make sure they are secured properly.
4. Please check the brakes.

Weight limitation.
1. Please refer to the specifications table for weight capacity information. Power scooter is rated for
a maximum weight capacity.
2. Stay within the specified weight capacity for your scooter. Exceeding the weight capacity voids
your warranty. Heartway will not be held responsible for injuries or property damage resulting
from failure to observe weight limitations.
3. Don't carry passengers on scooters. Carrying passengers on scooter may affect the center of
gravity, resulting in a tip or a fall.

Tire inflation
1.
If your scooter is equipped with pneumatic tires, it is necessary to check the air pressure at least
one time a week.
2.
Proper inflation pressures will prolong the life your tires and ensure the smooth operation while
riding.
3.
Do not under-inflate or over-inflate your tires. It is critically important that 30-35 psi (2-2.4bar) tire
pressure be maintained in pneumatic tires at all times.
4.
Inflating your tires from an unregulated air source could over-inflate them, resulting in a burs tire.

Temperature
1.
Some of the parts of the power scooter are susceptible to change in temperature. The controller
can only operate in temperature that ranges between -25℃ ~ 50℃ .
2.
At extreme low temperatures, the batteries may freeze, and your power scooter may not be able
to operate. In extreme high temperatures, it may operate at slower speeds due to a safety
feature of the controller that prevents damage to the motors and other electrical components.

ELECTROMAGNETIC INTERFERENCE (EMI)

The rapid development of electronics, especially in the area of communications, has saturated our environment
with electromagnetic (EM) radio waves that are emitted by television, radio and communication signals. These
EM wave are invisible and their strength increases as one approach the source. All electrical conductors act as
antennas to the EM signals and, to varying degrees, all power wheelchairs and scooters are susceptible to
electromagnetic interference (EMI). The interference could result in abnormal, unintentional movement and/or
erratic control of the vehicle. The United States Food and drug Administration (FDA) suggests that the following
statement be incorporated to the user's manual for all power scooter like the S23. Power scooters may as
susceptible to electromagnetic interference (EMI), which is interfering electromagnetic energy emitted from
sources such as radio stations, TV stations, amateur radio (HAN) transmitter, two-way radios, cellular phones
