  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.
