Canon Compact Digital Camera Firmware Update Procedure
PowerShot S100
Firmware is software installed to control the equipment; it is the firmware that handles many of the compact
digital camera's operations, such as shooting or image processing. The instructions that follow explain the
steps for updating the camera with new firmware (by overwriting the existing firmware).
Make sure you have read the precautions and procedures below carefully before updating the firmware.
IMPORTANT: Observe the following precautions when updating the firmware
Please use a fully-charged, dedicated battery pack and a dedicated AC adapter kit to power the

camera.
Before updating the firmware, initialize the SD, SDHC or SDXC memory card in the camera. When you

initialize the SD memory card, any data written on it will be erased, so please be sure to save a copy of
any important data on the card to your computer or somewhere other than the card prior to initializing it.
Please be absolutely sure not to turn the power switch on the camera to OFF during the firmware

update. If using a household power source, please be careful about power outages.
During the firmware update, please do not open the battery cover or the memory card slot cover.

During the firmware update, please do not operate any of the camera's buttons, dials or switches.
