memo
◎ Depending on the operation procedure and usage
environment, the temperature inside the product may get
high and the product may even get heated. In such case,
charging may stop for security reasons.
◎ Charging the internal battery while using the camera
function etc. may lengthen the charging time.
◎ If you perform various operations with a specified charger
(sold separately) connected to the product, charging/
discharging may take place repeatedly in a short time.
Frequently charging the internal battery shortens its service
life.
◎ If you charge the internal battery when the battery has run
out, the charging/notification indicator may not illuminate
soon. However, charging is in progress.
◎ If the charging/notification indicator flashes in red, turn the
power off forcibly (zP.55) and turn it on. If the indicator
flashes even after that, stop charging the internal battery
and contact an au shop or Secure cell phone support
center.
◎ If you stop charging while the charging/notification indicator
still illuminates during charging, the internal battery may be
left not fully charged even if is displayed. In such case,
the usage times shorten.
