Troubleshooting
Bright red, green or blue dots appear on the screen.
- Try adjusting the black balance (A 52). 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,
200
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 the 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 recording media contains a large number of clips, some operations may take longer than usual. Save your
clips (A 170) and initialize the recording media (A 49). Alternatively, replace the recording media.
The camera cannot record to a CFast card properly.
- This may occur as recordings are made and deleted over time. Save your clips (A 170) and initialize the recording media
(A 49).
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.
Playback
Cannot delete a clip.
- You cannot delete clips with an $ mark. Remove the $ mark (A 155) to delete the clip.
- The LOCK switch on the SD card is set to prevent accidental erasure. Change the position of the LOCK switch.
Deleting clips takes longer than usual.
- When the recording media contains a large number of clips, some operations may take longer than usual. Save your
clips (A 170) and initialize the recording media (A 49).
Cannot delete a photo.
- 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 the camera.
Cannot copy clips.
- There is not enough available space on the CFast card being copied to or the CFast card already contains the
maximum number of clips (999 clips). Delete some clips (A 156) to free some space or replace the CFast card.
