Smudges on the image sensor Besides dust entering the camera from outside, in rare cases, lubricant from the camera's internal parts may adhere to the front of the sensor. If smudges are visible on images, have the sensor cleaned by a nearest Canon Service Center. Battery Tips for using the battery and charger Store in a cool, dry, well-ventilated location. When storing the battery for extended periods, charge it about once a year. When charging the battery, aim to charge it to approx. 50% instead of fully charging it ( ). At room temperature (23°C/73°F), it takes approx. 60 min. to charge a depleted battery to about approx. 50%. Battery charging time varies greatly depending on ambient temperature. If the battery is not used for an extended period, the trace amount of current that continues to flow inside the battery when it is removed from the camera may eventually lead to over-discharge and prevent further use, even after charging. 26
