Precautions

On the unit

  • The unit complies with the EU nickel release standard (EN1811). However, there might be a possibility that a person develops allergies. If the unit causes skin irritation, stop using it and consult a doctor or Sony representative.

On the waterproof property

  • The watch has a waterproof property equivalent to IPX5/IPX7 (see Specifications). However, do not allow water or dust to get inside the watch. Also, do not allow accessories to get wet or be exposed to dust.
  • The charging cradle and micro USB cable are not waterproof/dustproof. Do not use them in humid locations such as bathrooms, and avoid exposing them to rain. Note that if trouble is diagnosed as exposure to water or other liquid, repair of the unit may not be covered by warranty or repair may not be possible. Repair, when possible, is not covered by warranty and is carried out at cost.

On safety

  • Do not throw the unit into fire or apply heat.
  • Do not put the unit in a cooking apparatus such as a microwave oven or a pressure cooker.
  • If odor, overheating, discoloration, or deformation is detected during use, battery charge, or storage, immediately follow the instructions below:
    • If you are charging the watch, disconnect the micro USB cable.
    • Contact a Sony representative.
  • Do not disassemble or modify the unit.
  • Wireless functions are incorporated into the unit. Radio waves may affect the operation of other devices. Do not use the wireless function in the following locations.

    • near medical equipment (keep the watch 15 cm (5.9 in) or more away from an implanted cardiac pacemaker)
    • in crowded places or medical facilities
  • If the rechargeable battery leaks, do not touch the leakage with bare hands. Consult a Sony representative if the battery has leaked as battery liquid may remain in the unit. If the liquid gets into your eyes, do not rub your eyes as this may lead to blindness. Wash out your eyes with clean water and consult a doctor. If the liquid gets onto your body or clothes, wash it off immediately. Failure to do so may cause burns or injury. Consult a doctor if you are burned or injured by the liquid from the battery.
  • Do not touch the micro USB cable with wet hands.
  • If water or foreign objects get inside the watch, disconnect the micro USB cable immediately.
  • If water enters the watch or the watch fogs up and does not clear up even after a long time, consult a Sony representative for repair.
  • Be particularly careful when holding a small child. Take off the watch before holding a small child to avoid injury and accidents.
  • Be particularly careful when engaged in strenuous exercise or work, to avoid injury to yourself and others.

On placement

  • Do not expose the unit to direct sun light or ultra violet rays for many hours. It may cause discoloration of the unit.
  • Observe the following cautions, as there may be a risk of heat generation, fire explosion, electric shock, injury or malfunction.
    • Do not place the unit in locations subject to high temperatures (e.g. by a fire, near a heater, in direct sunlight, in a car in the hot sun).
    • Do not use the unit in a humid place such as bathroom, or in a dusty place.
    • Do not use the unit in a sauna or other location that may become excessively hot.

  • If paint thinner, benzene or other solvents or products containing these solvents (including gasoline, nail polish remover, cresol, bathroom cleaners and adhesives, etc.) are allowed to come into contact with the watch, they may discolor, dissolve, or crack the materials. Be careful when handling these chemicals. Contact with mercury such as that used in thermometers may also cause discoloration of the band and case.
  • Avoid spraying the unit with insect repellent. It may cause deformation or discoloration.
  • If the unit is not to be used for a long time, disconnect the micro USB cable, carefully wipe off any perspiration, dirt, or moisture, and store in a proper location, avoiding locations subject to excessively high or low temperatures and high humidity. If a battery with expired service life is left in the watch for a long time, battery leakage may damage the mechanical parts.

On handling the band
