When the system is to be used for the
first time or the battery is exhausted,
recharge the battery.
For details on charging, refer to the
“Startup Guide.”
Connect the AC-UD10 AC adaptor
(small) and the AC power cord to the
battery unit to start charging.
The (power) indicator is lit in orange
during charging, and the indicator
goes dark when charging is
completed (if the system power was
off).
• Charging is possible even while the
system is turned on, but longer charging
time is required. We recommend
charging with the system turned off
when the system is not to be used.
• Charging may not be possible or longer
charging time may be required
depending on ambient temperature or
other conditions of use.
– Perform charging under temperatures
from 5 °C to 35 °C (41 °F to 95 °F).
– Charging may not be performed in
wireless communication mode. In this
case, turn off the system power, or try
charging in wired communication
mode.
• The battery unit and the AC adaptor
become warm when the system is in use
or while charging. This is not a problem
for safety.
If the battery unit or the AC adaptor is
excessively hot, stop using the system
and turn off the system power.
Charging time and operating time
The charging time and the operating
time are as follows at room
temperature of 23 °C (74 °F).
• The charging time and operating time
may differ, depending on ambient
temperature, the battery condition and
other conditions of use.
• Longer charging time is required or
charging is not completed in the
following cases:
– when the system is used in wireless
communication mode
– when equipment is connected to the
battery unit and operated in MHL
connection
– under high ambient temperatures
• The operating time is shorter when
wireless communication conditions are
poor.
