Getting Ready
Charging the Battery Pack
The battery pack is not fully charged at the time of purchase. Charge the
battery pack when you use the PTL21 for the first time or when the battery
level becomes low.
◎ The PTL21 and the battery pack may become warm while charging. This is not
a malfunction.
◎ Read carefully the Safety Precautions “安全上のご注意” in the Instruction
Manual (Japanese) before using the battery pack.
◎ The charging time may become longer depending on the function used
while charging.
◎ When using the PTL21 with the specified charger (sold separately) connected
for charging, it may induce a repetition of small charging periods/electrical
discharges. Repeatedly charging the PTL21 may shorten the battery life.
◎ If the PTL21 charging indicator flashes in red, check that the battery is correctly
installed and that the cable is connected. If the indicator keeps flashing, stop
charging and contact an au shop or the Customer Service Center.
◎ The common AC adapter 01 (sold separately) is for use in Japan with
100V AC power supply. Do not use it with single-phase 200V power
supply or voltage transformers.
When charging with a specified AC adapter (sold separately), other than the
common AC adapter 01 (sold separately), outside Japan, use a plug adapter
according to your destination. Do not charge the PTL21 using a voltage
transformer.
◎ After charging, make sure to close the external connection jack cover
securely, and do not pull or twist it forcefully.
■Charging with the specified AC adapter (sold separately)
directly connected to the PTL21
The specified AC adapter (sold separately) is required. (The AC
adapter appearance in the figure may differ from the actual shape of
the adapter you are using).
The following is an explanation of how to charge your PTL21 using the
common AC adapter 03 (sold separately).
◎ When charging with the common AC adapter 01 (sold separately), the common
AC adapter 02 (sold separately) or an AC adapter with specifications similar
to the common AC adapter 02, use the 18pin-microUSB conversion adapter
01(sold separately) to make the connection to the PTL21.
◎ When starting charging with the PTL21 turned off, it automatically turns on and
the charging screen appears. Cell phone operation cannot be performed when
only the charging screen is displayed. When charging is finished, the PTL21
automatically turns off.
◎ When charging the PTL21 with the power turned off, if charging is stopped
while the battery is almost empty, a message prompting to charge the battery
may appear.
