THE BATTERIESTHE BATTERIES

1.We recommend deep-cycle batteries that are sealed and maintenance
free. Both sealed lead-acid and gel cell are deep-cycle batteries that
are similar in performance in your HERO. Do not use wet-cell
batteries, which have removable caps.

3.Following rules will keep the batteries work longer:
Avoid charging after the batteries use out, charging after all day
HERO use on a daily basis.
Unplug the hub in 40 hours after the batteries fully charged.
Charge every three days to keep the batteries full after infrequent
or sporadic HERO use.

-21--21-

Do not remove the caps from sealed batteries. Water cannot be added
to sealed batteries.
Avoid using the batteries in an airless place.
The batteries acid could cause blindness or burning. If the batteries
acid contacts eyes, skin, clothes, or articles, rinse with water as soon
as possible. If battery acid is ingested, drink lots of water, and seek
medical assistance immediately.
Do not use other HERO's batteries to avoid damage to your HERO.
When your HERO is being transported, make sure your HERO and its
batteries are secured.

The batteries would degenerate and the drive distance would decrease
after normal use for some time.
You can change the batteries if the drive distance becomes half after
charging full.
Change two batteries at the same time to optimize the best effect.

EMI/RFIEMI/RFI

Laboratory tests performed by the Food and Drug Administration FDA

have shown that radio waves can cause unintended motion of electric

HERO. Radio waves are a form of electromagnetic energy EM .When

electromagnetic energy adversely affects the operation of an electrical

device, that adverse effect is called Electromagnetic Interference EMI

or Radio Frequency Interference RFI .

The following FAQ summarize what you should know about EMI/RFI. Use
this information to minimize the risk that EMI/RFI will adversely affect
your HERO.

Radio waves are emitted from the antennas of cellular phones, mobile

two-way radio such as walkie-talkies and CBs , radio stations, TV

stations, amateur radio HAM transmitters, wireless computer links,

microwave sources, and paging transmitters. Radio waves are a form of

EM. Because EM is more intense closer to transmitting antennas

sources of emission , the EM fields from two-way radios are of special

concern to electric HERO users.

EMI/RFI Warnings

EMI/RFI Frequently Asked Questions FAQS

Where do radio waves come from?

This is difficult to predict. The answer would depend on a number of
factors:
The strength of the radio waves.
The construction of your particular HERO.
The location of your HERO whether it is on level ground or on an
incline .
Whether or not your HERO is in motion.
The motion of any electric HERO affected by EMI/RFI can be erratic.
The HERO may come to a sudden stop or move in an uncontrolled
manner. Also, it is possible for EMI/RFI to release the brakes of an
electric HERO. Some intense EMI/RFI can even damage the control
system components of an electric HERO.

If EMI/RFI affects my HERO, what kind of motion should I expect?

-22--22-

EMI/RFIEMI/RFI

Unfortunately, EMI/RFI may be difficult to recognize, since the signals
from radio sources are invisible and may be intermittent. However, the
FDA recommends that you report all incidents of unintended motion or
unintended brake release of your electric HERO to the HERO's
manufacturer and, if possible, determine whether or not there was a
radio wave source nearby at the time of the incident.
One precaution you can take against inadvertent motion of your HERO is
to make certain that you or someone else is not the cause of the
unintended motion.
Turn off your HERO by removing the key from the key switch when you
are getting on or off your HERO.
Never leave the key in the key switch of an unattended HERO.

Each make and model of electric HERO differs in its ability to resist
EMI/RFI. That is, each HERO has a particular level of resistance to
EMI/RFI. This resistance is measured in volts per meter V/m . A higher
resistance level offers greater protection against EMI/RFI. In other words
, an electric HERO with a high resistance level is less likely to be affected
by a strong radio source than is an electric HERO with a low resistance
level.

The FDA has written to electric HERO manufacturer and requested that

those manufactures test their new models of HERO to be certain that

they provide a reasonable degree of resistance against EMI/RFI. The

FDA has stated that all newly manufactured models of electric HERO

should have a resistance level of at least 20 V/m. This resistance level

provides a reasonable degree of protection against the common sources

of EMI/RFI.

Is there any way to know for certain whether or not radio waves are
the cause of any unintended motion of my HERO?

Are all HERO's susceptible to EMI/ RFI ?

What is the FDA doing about the problem?

-23--23-

EMI/RFIEMI/RFI

Electric HERO manufacturers clearly label new products with that
product's resistance level or state that the resistance level is not known.
The labeling or informational material supplied with new electric
HERO must explain what the resistance level means and warn users
about the possibility of EMI/RFI and hoe to avoid it.
Electric HERO manufacturers undertake an educational program to
inform electrical HERO users and their caregivers about the problems
associated with EMI/RFI and about the actions they can take to minimize
the risk of EMI/RFI.
While there is no exact way to tell if your HERO is totally safe, an
immunity level of 20 V/m is generally achievable and useful. This
product has been tested and passed at an immunity level of 20 V/m.
Adding accessories and components or modifying the unit may change
the susceptibility to EMI/RFI.

If you have had your HERO for some time and have not experiences any
unintended motion, it is not likely that you will have a problem in the
future. However, it is always possible that EMI problems could arise if
you are close to a source of radio waves. Therefore, it is very important
for you to be alert to this possibility.

Here are some precautions you can take:
Do not turn on or use hand-held personal communications devices,
such as citizen's band CB radios an cellular phones, while your
HERO is turned on.
Be aware of nearby radio wave transmitters, such as radio or TV
stations and hand-held or mobile two-way radios. Try not to operate
your HERO too close to those transmitters. For example, if you are on
an electric HERO with a resistance level of at least 20V/m, you should
remain at least three feet from a hand-held two-way radio and at least
ten feet from a mobile two-way radio.
Be aware that adding accessories and/ or components, or modifying
your HERO in any way, may change its EMI/RFI resistance level and
may make it more susceptible to interference from radio wave sources.

The FDA has also requested or recommended that:

What can I do to find out if my HERO is likely to be affected by EMI/RFI?

What can I do to reduce the risk of my HERO being affected by EMI/RFI?

-24--24-

What should I do if my HERO moves unexpectedly?

If unintended motion or unintended brake release occurs, turn off your
HERO by removing key as soon as it is safe to do so.

MAINTENANCEMAINTENANCE

Please charge after prolong driving.
