Charging

. If the operation lamp starts flashing red...
If the operation lamp starts flashing red during charging, it means that further
charging is not possible for one of the reasons below. Perform the actions described
below to correct the problem and then try charging again.
Ambient temperature or the temperature of the battery is abnormally high
or low
Unplug the USB cable from the product and wait for a while until the product is within
the temperature range of 15°C to 35°C (59°F to 95°F), and then try charging again.
Safety timer activated
A battery that has not been used for a long time, certain types of computers, and
connection conditions can cause charging to take longer than normal. If charging
takes about five hours, a safety timer will terminate it automatically, even if the battery
is not fully charged. If the battery has not been used for a very long time, charging
may terminate automatically after only about 60 minutes.
1) Using a battery that has not been used for a long time.
Disconnect and then reconnect the USB cable to resume charging.
2) Insufficient power supply when connected to computer
The product can be charged only via a USB 2.0 standard USB port. Connect
directly to a USB port that supplies a current of 500mA.
For details about the power supply capacity of a computer's USB port, contact the
manufacturer of the computer. Though disconnecting and then reconnecting the USB
cable will resume charging, you may need to do so repeatedly if the power supply
capacity of the computer is low.
If problems persist after you perform the above steps or if the battery fails to
charge after 5 hours, it could mean that the battery is faulty. Contact your nearest
CASIO authorized service center.
