SAFETY INFORMATION ON ELECTROMAGNETIC INTERFERENCE (EMI)

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 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. This immunity level of this motorized scooter model is 20 V/m.
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; 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.

Motorized Scooter Electromagnetic Interference :
Because EM energy rapidly becomes more intense as one move 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.

Warnings :
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
    **** There is no easy way to evaluate their effect on the overall immunity of the motorized scooter.

  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 20 V/m.

rechargeable batteries and one 2A On-board charger. Batteries must be charged before using scooter for first time and should be recharged after each day’s use. Be sure power switch is in OFF position and free-wheeling lever is not in freewheel mode.
For safety reasons, only sealed non-spillable batteries that meet DOT CFR 173.159(d), IATA Packing Instructions, and IATA Provision A67 shall be installed in the scooters. If you need new batteries, contact your dealer. Only 12V. 18Ah Valve-regulated Lead Acid batteries should be used.

  1. Insert battery charger cord into Charging Socket (P) on battery pack.

  2. Plug other end of Power Cable (Q) into a standard electrical wall outlet.

  3. The charging indicator will normally be red or yellow at this point.

  4. Allow batteries to charge until charging indicator turns green.

  5. After indicator turns green, unplug battery charger from scooter and wall outlet.

  6. Do not charging simultaneously with battery box socket and optional charging socket, this will cause serious risk.

  7. If at any time battery charger light flashes green over 40 minutes, this indicates abnormal charging occurred.
    You should check the following :
    • Charger plug is correctly positioned
    •  Scooter is turned off
    •  If none of these are the problems, contact your local authorized dealer.

**** The time needed to recharge will vary depending on the depletion of the batteries. Charging for longer than necessary will not harm the batteries.
They can not be overcharged.

Keep in mind these rules :

  • Fully charge batteries at least once a month, or more if you use scooter regularly.
    Charge after each trip exceeding 3 kilometers.

  • If storing your scooter for some time (1 month or more), make sure that batteries are fully charged, and on returning, charge them again before using scooter.

  • Batteries will only give maximum performance after scooter has been used, and batteries have been recharged up to 10 times. A bit like breaking in a new car.

Please be aware that the travelling range of your mobility scooter is impacted by how fast the batteries are discharged. This will depend on many circumstances, such as ambient temperature, condition of the surface of the road, tyre pressure, weight of the driver, driving environment (inclines etc.) and utilisation of your lighting system if fitted. We recommend that you test your local ride with a family member to ensure a safe journey.
