As you begin using your scooter during daily activities, you will probably encounter situations in which you will need some practice. Simply take your time and you will soon be in full and confident control as you maneuver through doorways, on and off elevators, up and down ramps, and over moderate terrain. Before you get use to driving the scooter, please practice in advance at a safe and open place. Upon getting use to it, you may drive on a road. Consult your physician if you are taking any prescribed or over-the-counter medication which may impair your operation of the scooter. The first time operating the scooter road, you should be attended by a family member or a friend. Avoid snaking, forging, abrupt turn, and abrupt stop. Keep a lookout for pedestrians, obstacle, and pothole particularly when reversing. Do not drive under the influence of alcohol or drug, speak to your doctor first if you are unsure about driving or taking medication. Avoid putting all of your weight on the floorboard. Such an action may cause your scooter to tip and result in personal injury. Some medications limitations may impair your ability to operate your scooter in a safe manner. Avoid carrying or hauling. Comfort scooter is designed for one person only, passengers are prohibited. Do not use your scooter to negotiate steps or escalators. You may injury yourself and others or damage your scooter. Do not bend, lean, or reach for objects .If you have to pick them up from the floor by reaching down between your knees. Such use may cause your scooter to tip and result in personal injury. Ramp Obstacle Approach slowly, as you encounter a ramp or incline. Do not drive up or down an incline that is more than 12 degree. If you must stop when climbing, accelerate slowly. Avoid prolong climbing When driving down a ramp, keep your scooter's speed adjustment set to the lowest speed setting and driving in the forward direction only. On any sort of an incline or decline, never place your scooter in freewheel mode while seated on it or standing next to it. -2- SAFETY Do not attempt to climb over an obstacle which is more than 75mm high or 100mm width. Do not attempt to have your scooter proceed backwards down any step, curb, or other obstacle. Cornering Information Excessively high cornering speeds can create the possibility of tipping. Factors which affect the possibility of tipping include, but are not limited to, cornering speed, steering angle how sharply you are turning , uneven road surfaces, inclined road surfaces, riding from an area of low traction to an area of high traction such as passing from a grassy area to a paved area especially at high speed while turning , and abrupt directional changes. High cornering speeds are not recommended. If you feel that you may tip over while cornering, reduce your speed and steering angle to prevent your scooter from tipping. WARNING When cornering sharply, reduce your speed. When using your scooter at higher speeds, do not corner sharply. This greatly reduces the possibility of a tip or fall. To avoid personal injury or property damage, always exercise common sense when cornering. Take wide swings with your scooter's front wheel around any tight corners, and your scooter's rear wheels will follow a wide arc. Not cut the corner short, and not bump into or get hung up on any railing corners.

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 E;ectromagnetic Interference EMI or Radio Frequency Interference RFI . EMI/RFI Frequently Asked Questions FAQS The following FAQs summarize what you should know about EMI/RFI. Use this information to minimize the risk that EMI/RFI will adversely affect your scooter. Where Do Radio Waves Come From? 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 scooter users. If EMI/RFI Affects My Scooter, What Kind Of Motion Should I Except ? 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 scooter. The location of your scooter whether it is on level ground or on an incline . Whether or not your scooter is in motion. The motion of any electric scooter affected by EMI/RFI can be erratic. The scooter 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 scooter. Some intense EMI/RFI can even damage the control system components of an electric scooter. -34- EMI/RFI Is There Any Way To Know For Certain Whether Or Not Radio Waves Are The Cause Of Any Unintended Motion Of My Scooter ? 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 scooter to the scooter'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 scooter is to make certain that you or someone else is not the cause of the unintended motion. Turn off your scooter by removing the key from the key switch when you are getting on or off your scooter. Never leave the key in the key switch of an unattended scooter. By following these steps, you greatly reduce the risk of you or anyone else inadvertently bumping the throttle control levers and causing the scooter to move unintentionally. Are All Scooters Susceptible To EMI/RFI ? Each make and model of electric scooter differs in its ability to resist EMI/RFI. That is, each scooter 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 scooter with a high resistance level is less likely to be affected by a strong radio source than is an electric scooter with a low resistance level. What Is The FDA Doing About The Problem? The FDA has written to electric scooter manufacturer and requested that those manufactures test their new models of scooters 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 scooters 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. -35- EMI/RFI The FDA Has Also Requested Or Recommended That : Electric scooter 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 scooters must explain what the resistance level means and warn users about the possibility of EMI/RFI and how to avoid it. Electric scooter manufacturers undertake an educational program to inform electrical scooter 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 scooter 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. What Can I Do To Find Out If My Scooter Is Likely To Be Affected By EMI/RFI? If you have had your scooter 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 you are close to a source of radio waves.Therefore, it is very important for you to be alert to this possibility. What Can I Do To Reduce The Risk Of My Scooter Being Affected By EMI/RFI? 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 scooter 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 scooter too close to those transmitters. For example, if you are on an electric scooter 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 scooter in any way, may change its EMI/RFI resistance level and may make it more susceptible to interference from radio wave sources. -36- MAINTENANCE Daily Care Please charge the batteries after prolong driving. Keep your scooter in a dry place or put a waterproof over it to prevent moisture ingress when it is not being used. Please wipe your scooter with dry clean cloth as often as possible.
