using it for the first time, or if it has not
been used for more than 2 months. The
charger automatically restarts charging
when the battery voltage drops.
• Disconnect the AC adapter from the outlet
when not charging the battery.

supported.
• The charging time may differ, depending
on the current. When you use a lower
than 1 A output AC adapter or PC, it may
take longer to charge, or the battery may
not be charged.
• Before using the AC adapter, thoroughly
read its instructions.
NOTE: If "Q ER" is displayed, a charging
error has occurred.

adapter, and then connect properly.
