After less than a month on the market, the EX-FH20 has a firmware update. Casio has made the update for its speedy new camera available on its website. The update will improve the performance of the EX-FH20′s memory card storage when shooting movies. A CLASS6 equivalent transfer speed memory card is recommended for the camera.
The firmware update is version 1.01, and Casio has posted a special warning for EXILIM owners updating their cameras:
If firmware update installation is interrupted due to low battery power, your camera will no longer be able to operate. Be sure to load a fresh set of new batteries into the camera before starting the firmware update installation procedure. Note that you perform firmware update at your own risk.
