Auto Temperature Cutout

G button U B setup menu

The level at which the camera will turn off automatically as its internal temperature rises can be selected from [Standard] and [High].

When [Standard] is selected, the camera will display first a J and then a K icon as its internal temperature rises, switching to a count-down timer if the temperature increases still further.
When [High] is selected, the camera will display J, K, and M icons as its internal temperature rises, switching to a count-down timer if the temperature increases still further.
When the count-down timer reaches zero, the camera will turn off automatically and further photography will be suspended.

Caution: “High”

Although selecting [High] gives you more time before the camera shuts down, the camera may become hot to the touch. We recommend using a tripod or other equipment to reduce the time spent touching the camera.

Cautions: When the Camera Is Hot

In some cases, the count-down timer may be displayed the moment the camera is turned on, even when [High] is selected.
Image quality may drop when the camera is hot.
Memory cards inserted in a hot camera may also become hot. Wait for the temperature to drop before handling the camera or memory cards.
