  1. The continuous call time and continuous standby time listed are average time lengths for usage from combined moving and fixed locations with normal signal reception. The actual times for which the phone can be used will vary widely depending on a variety of conditions, including calling time, number of calls, email composing time, number of sent and received emails, usage conditions of Internet and applications, and network conditions. (More frequent usage or poor signal reception shortens these times. Less frequent usage extends the times.)
  2. This figure has been confirmed through the operation test following KDDI's standard. With some models, copyrighted data that can be stored in external storage is transferable to secured external memories. However, note that the availability varies depending on the manufacturers: some microSD™ cards, microSDHC™ cards and microSDXC™ cards even with the above-mentioned specifications may be unsupported.
  3. The entire memory capacity cannot be used to save apps and data.
  4. Be sure the card slot cover and caps on devices with these are securely fastened and the battery cover on devices with a removable battery cover is firmly in place.
    Do not immerse the unit in ocean, pool, or hot spring water. Do not place the unit on the sand.

  1. The number of entries depends on the amount of free space in the device memory.
  2. IPX5 rating: The unit will retain its functionality as a phone even if blasted with water projected at all angles through 6.3 mm nozzles at a flow rate of approximately 12.5 liters per minute for more than 3 minutes from a distance of approximately 3 meters. IPX7 rating: Water will not leak inside and the unit will retain its functionality as a phone even if it is gently immersed in a tank of still tap water at room temperature at a depth of 1 meters and placed on the bottom for approximately 30 minutes.
  3. IP5X rating: When the unit is churned for 8 hours inside a dust resistance testing tube, the unit maintains its functionality and safety even when test dust (a diameter of 75 µm or less) enters the unit.
