Troubleshooting When a subject flits across in front of the lens, the image appears slightly bent. - This is a phenomenon typical of CMOS image sensors. When a subject crosses very quickly in front of the camera, the image may seem slightly warped. This is not a malfunction. Bright red, green or blue dots appear on the screen. - Try adjusting the black balance (A 49). The camera's CMOS sensor is a delicate piece of precision engineering. Direct exposure of the sensor to ion rays or other types of cosmic radiation may affect it and this may rarely appear as bright colored dots on the screen. This is the nature of CMOS image sensors and does not represent a malfunction. - The effects of the damage may be more noticeable when the camera is used in places subject to high temperatures, when a high ISO speed or gain level is used and when slow shutter speeds are used. Abnormal images appear on the screen and the camera cannot record properly. - While recording using an almost empty battery pack together with an AC adapter, the AC adapter was inadvertently disconnected or the power supply was suddenly interrupted. Reconnect the AC adapter and turn the camera off and then on again or replace the battery pack with a fully charged one. Changing between recording (ÜREC) and record standby (STBY) takes longer than usual. - When the card contains a large number of clips, some operations may take longer than usual. Save your recordings and initialize the card (A 46). Alternatively, replace the card. Clips or photos cannot be recorded properly. - This may occur as clips and photos are recorded/deleted over time. Save your recordings and initialize the card (A 46). After using the camera for a long time, it becomes hot. - The camera may become hot after using it continuously for long periods of time; this is not a malfunction. If the camera becomes unusually hot or it becomes hot after using it only for a short while, it may indicate a problem with the camera. Consult a Canon Service Center. 207 Playback Cannot delete clips/photos - XF-AVC clips with an $ mark cannot be deleted with the camera. Remove the $ mark (A 140). - The LOCK switch on the SD card is set to prevent accidental erasure. Change the position of the LOCK switch. - Photos that were protected using other devices cannot be deleted with this camera. Deleting clips takes longer than usual. - When the card contains a large number of clips, some operations may take longer than usual. Save your recordings and initialize the card (A 46). Indicators and Onscreen Displays appears in red on the screen. - Battery pack is depleted. Replace or charge the battery pack. í appears on the screen. - The camera cannot communicate with the battery pack attached so the remaining battery time cannot be displayed. The tally lamp does not illuminate. - Set > [B System Setup] > [Tally Lamp (Front)] or [Tally Lamp (Rear)] to [On]. The tally lamp flashes quickly. (4 flashes per second) - The battery pack is depleted. Replace or charge the battery pack. - There is not enough available space on the CFexpress cards. Delete recordings (A 141) to free some space or replace the CFexpress card. - A system error has occurred. Turn the camera off and then on again. If this does not solve the problem, consult a Canon Service Center. The tally lamp flashes slowly. (1 flash per second) - The combined available space on the CFexpress cards is low. Replace the CFexpress card that is not being used for recording.
