Sharp AQUOS sense7 Quick Start Manual page 33

● Use in very hot or cold environments, for example, when left in an
automobile with the windows closed in summer, will cause the
internal battery capacity to drop and shorten the available battery
usage time. This will also shorten the internal battery's service life.
Try to use the internal battery as much as possible at room
temperature.
● The internal battery gradually discharges after charging even if the
product is not used. The internal battery may discharge completely
after long time no use. Charge before using the product.
● Internal batteries sometimes swell up as they approach the end of
their service life depending on the usage condition. This is due to the
properties of lithium-ion batteries, and is not a problem in terms of
safety.
● The internal battery is a consumable item. If the performance of the
internal battery does not recover and deteriorates (e.g. the usable
time after each charge has become extremely short or the internal
battery swells), the internal battery is at the end of service life, so stop
using it and contact us at the inquiries listed on the last page of "取扱
説明書 詳細版 (Full Instruction Manual)" (Japanese). Note that the
length of service life varies depending on the usage condition, etc.
● Because the internal battery performance or service life will become
low, do not store the product in the following conditions.
• Battery level is full (soon after charging is complete)
• Battery level is empty (to the extent that the product is not powered
on)
• In extremely hot or humid conditions
■ SIM card
● Do not forcibly remove or insert the SIM card. Be careful not to exert
excessive force when inserting the card into your cell phone.
● You are responsible for any damage caused by inserting your SIM
card into some other IC card reader/writer, etc.
● Do not put stickers etc. on the SIM card.
● Do not insert the SIM card attached with a conversion adapter. Doing
so might cause a fault.
● Do not subject the SIM card to actions that can damage it (use in
high-temperature conditions, throwing in a fire, allowing metal
contacts to come in contact with foreign objects, subjecting to shock,
bending or pressing, wetting, etc.). Doing so might erase data or
cause a fault.
