Charging
. If the [ ] lamp flashes red while charging
This indicates that charging is not possible due to the reasons below. Follow the
instructions provided and try charging again.
Ambient temperature or battery temperature is too high or low.
Unplug the USB cable, leave it at room temperature for a while, and then try
charging again when ambient temperature is in the range of 10°C to 35°C.
Charging Timer
Depending on the model of computer you are using for charging, the connection
environment, and non-charging of the battery for a very long period, charging may
take a long time. If charging continues for longer than about five hours, a timer will
cause charging to stop even if the battery is not fully charged.
In addition, if a battery has not been used for a very long time, charging may stop
after about 60 minutes.
1) Battery is not charged after a long time.
Unplug the USB cable and plug it back in to resume charging.
2) When charging with a computer, if sufficient power is not supplied because of
the connection environment.
Charging of this product is possible only from a USB 2.0 port. Plug directly into
a USB port that can supply a current of about 500mA.
If you still get an error after taking the above steps or if charging does not
end after more than five hours, it probably means that the battery is defective.
Please contact a local authorized CASIO Service Center or your original
retailer.
Battery Use Precautions
• Due to battery characteristics, use in a cold location will shorten the battery
operating time, even if the battery is fully charged.
• Charge the battery in an environment with an ambient temperature of 10°C to
35°C. If the ambient temperature is out of this range, charging may take longer
or full charging may not be possible.
• If battery operating time is significantly shortened or even ends immediately
after charging, it probably means that the battery has reached the end of its
service life and needs to be replaced with a new one. Always request battery
replacement from a local authorized CASIO Service Center or your original
retailer. You cannot replace the battery yourself.
• If you do not use the product for a long time, fully charge the battery about
once every three months to prevent over-discharging.
