  • Some people (about 1 in 4000) may have seizures or blackouts triggered by light flashes or patterns, such as while watching TV or playing video games, even if they have never had a seizure before.
  • Anyone who has had a seizure, loss of awareness, or other symptom linked to an epileptic condition should consult a doctor before playing a video game.
  • Parents should watch when their children play video games. Stop playing and consult a doctor if you or your child have any of the following symptoms:

      Convulsions Eye or Muscle Twitching Loss of Awareness

      2. Do not play if you are tired or need sleep.
      3. Play in a well-lit room.

    WARNING - Repetitive Motion Injuries and Eyestrain
    Playing video games can make your muscles, joints, skin or eyes hurt after a few hours. Follow these instructions to avoid problems such as tendinitis, carpal tunnel syndrome, skin irritation or eyestrain:

    • Avoid excessive play. It is recommended that parents monitor their children for
      appropriate play.
    • Take a 10 to 15 minute break every hour, even if you don't think you need it.
    • If your hands, wrists, arms or eyes become tired or sore while playing, stop and rest them for several hours before playing again.
    • If you continue to have sore hands, wrists, arms or eyes during or after play, stop playing and see a doctor.


    The Nintendo DS contains a rechargeable lithium ion battery pack. Leakage of ingredients contained within the battery pack, or the combustion products of the ingredients, can cause personal injury as well as damage to your Nintendo DS. If battery leakage occurs, avoid contact with skin. If contact occurs, immediately wash thoroughly with soap and water. If liquid leaking from a battery pack comes into contact with your eyes, immediately flush thoroughly with water and seek medical attention.

    To avoid battery leakage:

    • Do not expose battery to excessive physical shock, vibration, or liquids.
    • Do not disassemble, attempt to repair or deform the battery.
    • Do not dispose of battery pack in a fire.
    • Do not touch the terminals of the battery, or cause a short between the terminals with a metal object.
    • Do not peel or damage the battery label.

    WARNING - Radio Frequency Interference

    The Nintendo DS can emit radio waves that can affect the operation of nearby electronics, including cardiac pacemakers.

    • Do not operate the Nintendo DS within 9 inches of a pacemaker while using the wireless feature.
    • If you have a pacemaker or other implanted medical device, do not use the wireless feature of the Nintendo DS without first consulting your physician or the manufacturer of your medical device.
    • Observe and follow all regulations and rules regarding use of wireless devices in locations such as hospitals, airports, and on board aircraft. Operation in those locations may interfere with or cause malfunctions of equipment, with resulting injuries to persons or damage to property.


    1. Do not disassemble or try to repair the Nintendo DS, components or accessories. Doing so voids your warranty.
    2. Always turn the Nintendo DS power OFF before loading or removing a Game Card. Insert the Game Card completely until it clicks into place, without forcing either the Game Card or the Nintendo DS.
    3. Do not store the Nintendo DS in a humid place, on the floor or in any location where it may contact moisture, dirt, dust, lint, or other foreign material.
    4. Do not drop, hit or otherwise abuse the Nintendo DS, components or accessories. This may damage the LCD screens or other precision components of the Nintendo DS.
    5. Make sure all connections to the Nintendo DS are made carefully and inserted into the correct locations only. Hold plugs straight when inserting them into a socket.
    6. When disconnecting any plugs from the Nintendo DS or wall outlet, first turn the Nintendo DS OFF. Then carefully pull by the plug itself rather than by the cord. Do not step on, sharply pull or bend any wires or cables. Do not expose the Nintendo DS, Game Cards or any of the Nintendo DS components or accessories to extreme heat or cold. The liquid crystal displays (LCD) may become slower or may not work when the temperature is low. The LCD will deteriorate at a high temperature. Take care not to expose the Nintendo DS to direct sunlight for extended periods of time.
    7. The LCD screens may be damaged by sharp objects or pressure. Take great care to protect the displays from scratches or stains.
    8. Connect ONLY accessories designed and licensed for use with the Nintendo DS to any external connectors.
    9. Do not spill liquids on the Nintendo DS, Game Cards or other components or accessories. If the Nintendo DS comes into contact with liquids, wipe clean with a soft, slightly damp cloth (use water only). Remove the battery cover and battery. If liquid came into contact with the battery, do not reuse it. Call Nintendo Customer Service at 1-800-255-3700 for further instructions on battery replacement and possible service to your Nintendo DS.
    10. Do not rapidly turn the power switch ON and OFF, as this may shorten the life of the battery and cause Game Cards to lose your stored game information.
    11. To avoid dirt or dust from getting into the Nintendo DS, always leave a Game Card and Game Boy® Advance Game Pak loaded (with the power off), when not in use.
    12. When using an AC adapter, make sure you are using the correct model appropriate for your Nintendo DS. Always unplug the AC apter from the wall outlet when not in use.
    13. Do not use the AC adapter if the cable or plug are damaged.
    14. The AC adapter is intended to be correctly oriented in a vertical or floor mounted position.


    1. Avoid touching the connectors with your fingers. Do not blow on them or allow them to get wet or dirty. Doing so may damage the Game Card and/or the Nintendo DS.
    2. The Game Card is a high precision electronic device. Do not store it in places that are very hot or cold. Do not hit, drop or otherwise abuse it. Do not attempt to take it apart.
    3. Do not clean with benzene, paint thinner, alcohol or any other solvent.
    4. Always check the Game Card edge connector for foreign material before inserting the Game Card into the Nintendo DS.
