  • Page 9: Operation Diagnosis Check

    1.3. Operation Diagnosis Check Depending on the extent of your disabilities, it may be dangerous to travel unaccompanied. Use this diag- nosis check as a guide to determine whether or not you can travel unaccompanied. WARNING ● Before using the wheelchair, be sure to assess your competence and determine whether or not you need an assistant. Moreover, in determining the necessity of an assistant, consult expert opinions as a point of reference.

  • Page 10: Assistive Operation Diagnosis Check

    1.4. Assistive Operation Diagnosis Check Use the diagnosis check below as a guide to determine whether or not you can provide assistive operation. WARNING ● If an assistant is to accompany you and operate the wheelchair, be sure to assess his or her competence. Moreover, when assessing the assistant’s competence, consult expert opinions as a point of reference. If your judgment is based solely on your own opinion, you or other people around you may get injured.
  • Page 11 1.5.2. Powered Wheelchair Electromagnetic Interference (EMI) 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 pos- sible to unintentionally bring high levels of EM energy very close to the powered wheelchair’s control sys- tem while using these devices.
  • Page 12 CAUTION IT IS VERY IMPORTANT THAT YOU READ THIS INFORMATION REGARDING THE POSSIBLE EF- FECTS OF ELECTROMAGNETIC INTERFERENCE ON YOUR POWERED WHEELCHAIR. Electromagnetic Interference (EMI) From Radio wave sources Powered wheelchairs and motorized scooters (in this text, both will he referred to as powered wheel- chairs) may be susceptible to electromagnetic interference (EMI), which is interfering electromagnetic energy (EM) emitted from sources such as radio stations, TV stations, amateur radio (HAM) transmitters, two-way radios, and cellular phones.
  • Page 13 1.5.3. Before Use Each Day WARNING ● Perform the daily checks before use every day. Make a habit out of inspecting the wheelchair. Continued use of the wheelchair with a problem in the wheelchair body or the wheels may cause damage to the wheelchair while traveling, and may result in a rollover or fall.
  • Page 14 1.5.4. Handling the Wheelchair WARNING ● Modifying the unit or its mounting may adversely affect its performance and safety. Never make any modifications. ● If the wheelchair has parts that are foldable or detachable, do not operate the wheelchair with those parts folded or removed. ● When lifting the wheelchair, do not hold movable parts. ● Do not operate with any heavy baggage hanging over the backrest, or with any heavy objects in the compartment. The wheelchair could easily fall backward on an inclined slope, and may cause you or people around you to get injured.
  • Page 15 ● While operating the wheelchair, be careful not to get your hands tangled in the wheel spokes, wheel holes, etc. ● The wheels of the NAVIGO 16″ are not equipped with hand rims. When operating the NAVIGO 16″, do not manually drive the wheelchair by holding its rear tires or wheels. You may injure yourself. ● When moving past hedgerows and trees, maintain a suitable distance to prevent the rear wheels from coming into contact with twigs or other protruding items. If twigs or other...
  • Page 16 1.5.5. Getting In/Out of the Wheelchair, Seating WARNING ● When getting in the wheelchair by yourself or when the assistant has the user of the wheelchair get in the wheelchair, ensure that the wheelchair is on a level ground. If the user attempts to get in the wheelchair on an incline, he or she may lose balance and fall off the wheelchair.
  • Page 17 The weak electromagnetic waves emitted by the NAVIGO may affect other electronic devic- es, such as automatic doors and the anti-theft systems of stores. In this case, turn off the power and operate the wheelchair using the assistant operations or manual operation.
  • Page 18 WARNING ● Do not ride with clothing that is unsafe for wheelchairs, such as shown below. If you drive with such clothing, you or other people around you may get injured. Long scarves Clothing with loose sleeves Bare feet, sandals, slippers, Pants/skirts with wide hems ill-fitting footwear, etc.
  • Page 19 In the following environments and situations, you may need an assistant to accompany you and to oper- ate the wheelchair for you. In such cases, have an assistant accompany you. Traveling alone in these situations may lead to injury. Moreover, check to see if any dangers such as those shown below exist in the roads you use on a daily basis.
  • Page 20 1.5.8. Operation on Slopes WARNING The wheelchairs equipped with the NAVIGO are built to be lighter compared to other heavier electric wheelchairs that use a heavier general lead battery. For this reason, when a person sits in it, the overall center of gravity may be different. Therefore, use caution when traveling on a slope.
  • Page 21 1.5.9. Going Up/Down Curbs WARNING The wheelchairs equipped with the NAVIGO are built to be lighter compared to other electric wheelchairs that use a heavier general lead battery. For this reason, when a person sits in it, the overall center of gravity may be different. Therefore, use caution when traveling on a curb.
  • Page 22 WARNING ● When traveling over a curb, be careful not to lose your balance. ● When traveling over a curb, proceed at a right angle to the curb. Do not traverse the curb diagonally. ● Because the front casters are small, they are able to travel over only small curbs. There- fore, caution is necessary when traveling over curbs in power drive mode. ● When traveling between a sidewalk and a road, be careful of curbs. ● To travel over a curb or other obstacles with the assistant operations, turn off the assistant controller and go over it manually. If the assistant goes over a curb or other obstacles in power drive mode, the assistant could easily lose balance and the passenger or assistant could get injured if the wheelchair tips over.
  • Page 23 WARNING ● When crossing a street at a crosswalk with no traffic light, pay sufficient attention to the traffic. ● If there is a pedestrian signal light, obey the signal light. If the signal light is flashing green or is red, you must not start to cross the road. ● If the street is wide, the signal may change before you finish crossing. In such places, wait for the next green light to give yourself enough time to cross the street. ● At intersections where there are no traffic lights or crosswalks, stop in the following three stages. 1. Stop before entering the road. 2. Stop where you can be seen by automobiles. 3. Stop where you have a good view of the road. 1.5.11.
  • Page 24 1.5.12. Poor Road Conditions WARNING The wheelchairs equipped with the NAVIGO or the are built to be lighter compared to other electric wheelchairs that use a heavier general lead battery. For this reason, when a person sits in it, the overall center of gravity may be different. Therefore, use caution when traveling on uneven surface.
  • Page 25 1.5.13. Parking Lots WARNING ● Do not travel directly behind or in front of automobiles in parking lots. Drivers may not be able to see you if you are directly behind or in front of their automobiles. ● Do not travel between automobiles in parking lots. Otherwise, you could damage the auto- mobiles or be crushed when an automobile starts moving. 1.5.14. Using Public and Private Transportation WARNING ● When using public transportation, check to ensure that wheelchair use is allowed before- hand.
  • Page 26 1.5.15. Crowded Areas ● When getting in the wheelchair in a crowded area, do so with sufficient attention to your surroundings. If you bump into people or objects, your body may plunge forward, or people around you may get injured. ● When you are stopped in a crowded area, be sure to turn off the power. If a person in your surrounding area hits the joystick with his or her hand or arm, the wheelchair may start moving unexpectedly, causing injury to people around you.
  • Page 27 WARNING ● Avoid storing in direct sunlight or in places where the temperature can get high. ● Do not wash by directly hosing it down with water. Also, do not wash with using steam. The electronic devices can get damaged, which may lead to malfunction. ● Do not clean with solvents such as gasoline or paint thinner. This may damage the painting and plastic parts. 1.5.17. Assistant Operations in an Emergency WARNING ● During assistant operations in case of an emergency, the assistant should switch the clutch levers to the manual position, and move the wheelchair to a safe location.
