Troubleshooting

If you have a problem with your camera, refer to this section. Consult your dealer or a Canon Service Center if
the problem persists.

Power source

The camera will not turn on or it turns off by itself.
- The battery pack is exhausted. Replace or charge the battery pack.
- Remove the battery pack and reattach it correctly.
Shortly after turning it on, the camera turns off on its own.
- You are using a battery pack that is not compatible for use with this camera. Use a recommended battery pack
(A 211).
Cannot charge the battery pack.
- The temperature of the battery pack is outside the charging range. If the battery pack's temperature is below 0 °C
(32 °F), warm it before charging it; if it is above 40 °C (104 °F), let the battery pack cool down before charging it.
- Charge the battery pack in temperatures between 0 °C and 40 °C (32 °F and 104 °F).
- The battery pack is faulty. Replace the battery pack.
The battery pack is exhausted extremely quickly even at normal temperatures.
- Check the [Battery/Hour Meter] status screen (A 197) to check if the battery pack has reached the end of its battery
life. If so, buy a new battery pack.
Recording
The camera's controls are not responsive/disabled.
- The grip unit's plug may not be correctly connected to the camera. When attaching the grip unit to the camera, make
sure the grip unit's plug is firmly inserted all the way into the connection terminal on the camera (A 43). If you
changed the angle of the grip unit, make sure you did not partially disconnect the plug by mistake.
- When the Q switch is set to C, all buttons (or all buttons with the exception of some START/STOP buttons) are
locked and cannot be operated. Set the Q switch to CAMERA. You can change which controls are locked with
the [System Setup] > [Custom Function] > [Key Lock] setting (A 144).
Pressing the START/STOP button will not start recording.
- The CFast card is full or it already contains the maximum number of clips (999 clips). Delete some clips (A 156) or
save your clips (A 170) and initialize the CFast card (A 49) to free some space. Alternatively, replace the CFast card.
- The START/STOP button that was used may be disabled. Change the current settings in the [System Setup] >
[Custom Function] > [START/STOP Button] submenu (A 144) to enable the use of the desired START/STOP
buttons.
- The camera may be set to a special recording mode. If the special recording mode is no longer necessary, return
[Recording/Media Setup] > [Recording Mode] to [Normal Recording] to end the special recording mode.
- You may not be able to start or stop recording while controls on the optional RC-V100 Remote Controller are being
operated. Stop using the remote controller and then press the START/STOP button.
The point where the START/STOP button was pressed does not match the beginning/end of the recording.
- There is a slight interval between pressing the START/STOP button and the actual start/end of recording. This is not a
malfunction.
The camera will not focus.
- The camera may not be able to focus on certain subjects using autofocus. Focus manually (A 78).
- When the AF mode is set to AF-boosted MF, start focusing manually until the AF frame changes to white (automatic
adjustment range).
- The viewfinder is not adjusted. Use the dioptric adjustment lever to make the proper adjustment (A 40).
- The lens is dirty. Clean the lens with a soft lens-cleaning cloth.
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.
