Notes About Charging with a Computer

• When connected to a computer, the camera turns on and starts charging. If the camera is 

turned off, charging stops.

• About 3 hours are required to charge a fully exhausted battery. Charging time increases 

when images are transferred while the battery is charging.

• The camera turns off automatically if there is no communication with the computer for 30 

minutes after the battery has finished charging.

When the Charge Lamp Quickly Flashes Green

Charging cannot be performed, possibly due to one of the reasons described below. 
• The ambient temperature is not suited to charging. Charge the battery indoors with an 

ambient temperature of 5°C to 35°C (41°F to 95°F).

• The USB cable is not connected correctly, or the battery is faulty. Make sure that the USB 

cable is connected correctly or replace the battery if necessary.

• The computer is in sleep mode and is not supplying power. Wake up the computer.
• The battery cannot be charged because the computer cannot supply power to the 

camera due to the computer’s settings or its specifications.
