IMPORTANT PRECAUTIONS
2
•The weight capacity limit at different ramp degree (please refer to following picture).
•The grade climbing degree will be affected by weight capacity, driving speed, and ramp degree, and scooter parameter.
•To prevent any danger from motor defected; please avoid to drive on long ramp or any uneven terrain.
85 kg / 9 degree 190 kg / 6 degree HS-928 226 kg / 3 degree
HS-915 190 kg / 3 degree
•Only one person at a time could ride a C.T.M. Mobility Scooter.
•Maximum load : HS-915 is 190 kgs / 419 ; HS-928 is 226 kgs / 498 pounds.
•Turn key off before getting on or off.
•Always drive carefully and be aware of others using the same area.
•Always use pedestrian crossings wherever possible. Take extreme care when crossing
roads.
•
Do not drive on slope exceeding 9 degree, and take extreme care when turning on slope.
•Do not use full power when turning to sharp corner.
•Take great care and drive in low speed when backing up, riding downhill or on uneven
surface, and climbing curb.
•Please use the lowest speed when driving through the descending road or uneven terrain.
If speed is too fast, leave your hand off the handle bar, let the scooter stop. Make sure
safety and start again.
•A slow speed must always be used when ascending, descending or traversing aslope
or incline and also on uneven terrain, ramps and soft or loose surfaces, such as gravel
or grass.
•To prevent any danger, do not turn around at high speed on ascending, descending ramp.
•Scooter may not operate well in high humidity.
•Do not leave the powered scooter in a rain storm of any kind.
•Do not use the powered scooter in a shower.
•Direct exposure to rain or dampness will cause the scooter to malfunction electrically
and mechanically; may cause the powered scooter to prematurely rust.
•Never put scooter in neutral when staying on slopes.
•Follow traffic laws when riding outside.
•When scooter on moving transport vehicles, do not sit or stay on scooter.

2.Medium-range mobile transceivers, such as those used in police cars, fire trucks,
ambulances, and taxis. These usually have the antenna mounted on the outside of the
vehicle; and
3.Long-range transmitters and transceivers such as commercial broadcast transmitters
(radio and TV broadcast antenna towers) and amateur (HAM) radios
Other types of hand-held devices, such as cordless phones, laptop
computers, AM/FM radios, TV sets, CD players, and cassette players,
and small appliances, such as electric shavers and hair dryers, so far as.
we know, are not likely to cause EMI problems to your motorized scooter.
ELECTROMAGNETIC INTERFERENCE
AND WARNINGS
3
CAUTION: It is very important that you read this information regarding the possible
effects of Electromagnetic Interference on your motorized scooter.
Powered wheelchairs and motorized scooters may be susceptible to electromagnetic
interference (EMI), which is interfering electromagnetic energy (EM) emitted from sources
such a radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios, and
cellular phones. The interference (from radio wave sources) can cause the motorized
scooter to release its brakes, move by itself, or move in unintended directions. It can also
permanently damage the motorized scooter control system. The intensity of the interfering
EM energy can be measured in volts per meter (V/m). Each motorized scooter can resist
EMI up to a certain intensity. This is called its "immunity level." The higher the immunity
level, the greater the protection. At this time, current technology is capable of achieving
at least a 20 V/m immunity level, which would provide useful protection from the more
common sources of radiated EMI. The immunity level of this motorized scooter model is
not known.
There are a number of sources of relatively intense electromagnetic fields in the everyday
environment. Some of these sources are obvious and easy to avoid. Others are not
apparent and exposure is unavoidable. However, we believe that by following the warnings
listed below, your risk to EMI will be minimized.
Some cellular telephones and similar devices transmit signals while
they are ON, even when not being used
The sources of radiated EMI can be broadly classified into three types :
1.Hand-held portable transceivers (transmitters-receivers) with the antenna mounted
directly on the transmitting unit. Examples include: citizens band (CB) radios, "walkie
talkie," security, fire, and police transceivers, cellular telephones, and other personal
communication devices

Instruction Booklet9-Series
4
There is no easy way to evaluate their effect on the overall immunity of
the motorized scooter.
Because EM energy rapidly becomes more intense as one moves closer to the transmitting
antenna (source), the EM fields from hand-held radio wave sources (transceivers) are of
special concern. It is possible to unintentionally bring high levels of EM energy very close
to the motorized scooter control system while using these devices. This can affect
motorized scooter movement and braking. Therefore, the warnings listed below are
recommended to prevent possible interference with the control system of the motorized
scooter.
Motorized Scooter Electromagnetic Interference：
Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur
radio (HAM) transmitters, two-way radios, and cellular phones can affect motorized scooters.
Following the warnings listed below should reduce the chance of unintended brake release
or motorized scooter movement which could result in serious injury.
1.Do not operate hand-held transceivers (transmitters-receivers), such as citizens band
(CB) radios, or turn ON personal communication devices, such as cellular phones, while
the motorized scooter is turned ON;
2.Be aware of nearby transmitters, such as radio or TV stations, and try to avoid coming
close to them;
3.If unintended movement or brake release occurs, turn the motorized scooter OFF as
soon as it is safe;
4.Be aware that adding accessories or components, or modifying the motorized scooter,
may make it more susceptible to EMI; and
Warnings：
1.20 volts per meter (V/m) is a generally achievable and useful immunity level against
EMI (as of May 1994). The higher the level, the greater the protection.
2.The immunity level of this product is at least 20/Vm.
5.Report all incidents of unintended movement or brake release to the distributor listed
on the inside front cover of this manual. Note whether there is a source of EMI nearby.
