ELECTROMAGNETIC INTERFERENCE

AND WARNINGS

CAUTION: It is very important that you read this information regarding the possible effects of Electromagnetic Interference on your power chair.

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 will be. 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.

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.

Some cellular telephones and similar devices transmit signals while they are ON, even when not being used.

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.

3

HS-2800 User's Manual

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.

Power Chair Electromagnetic Interference

：

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 power chair control system while using these devices. This can affect power chair movement and braking. Therefore, the warnings listed below are recommended to prevent possible interference with the control system of the power chair.

Warnings

：

Electromagnetic interference (EMI) from sources such as radio and TV stations, amateur radio (HAM) transmitters, two-way radios, and cellular phones can affect the power chair.

Following the warnings listed below should reduce the chance of unintended brake release or power chair 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 power chair 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 power chair OFF as soon

as it is safe;

4.Be aware that adding accessories or components, or modifying the power chair, may

make it more susceptible to EMI; and

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.

Important Information

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 unknown.

CHARGING THE BATTERIES

Your C.T.M. power chair is equipped with two, service free 12V 36Ah rechargeable batteries and one 24V/3A on-board charger. Batteries must be charged before using power chair for the first time and it is recommended to be charged up to 8 - 14 hours after each day's use. Be sure power switch is in OFF position and free-wheeling lever is in "D" position.

1.Insert charger cord into charger output at rear of power chair.

2.Plug the other end of power cord into a standard electrical wall outlet.

3.The purpose of ammeter is to indicate how much capacity is needed to fully charge

batteries. Once charger is warmed up, the ammeter needle may move up to three

amps, or as low as zero amps, as a sign in charging.

4.The ammeter needle will then vibrate on the zero once the batteries are fully charged.

5.Once batteries are fully charged, please unplug power cord from wall outlet and power

chair. The power cord should be stored in a safe and dry area until next use.

6.If charging your power chair for over 8 - 14 hours and it does not function, please check :

•fuse is not burned out

•power chair is turned off

•circuit breaker is pushed in

•if none of above is the problem, contact your authorized dealer.

The time needed to recharge will vary depending on depletion of batteries.

Charging for longer than necessary will not harm batteries. They cannot be overcharged.
