Terminating the Connection
While connected, movie shooting is not possible.

While connected, the following operations cannot be performed:

Multiple exposures, interval timer, RAW image processing, resizing,
movie editing, image transfer by camera operation,
cropping (EOS 5DS, EOS 5DS R)
In remote shooting, the AF speed may become slower.

Depending on the transmission range and connection status, image

display may be delayed, images may not be displayed smoothly, or
shutter release timing may be delayed.
In Remote Live View shooting, the rate of image transmission is slower

compared to a connection via an interface cable. Therefore, moving
subjects cannot be displayed smoothly.
While connected, battery power is consumed. If you will not use the

wireless communication functions for a prolonged period, terminate the
connection.
The wireless connection will also be terminated if you set the camera's

power to <2> or open the card slot cover or battery compartment
cover.
If the camera's auto power off is activated while connected, the

connection will be terminated. If necessary, set [52: Auto power off] to
[Disable]. To continue to use EOS Utility, perform the reconnection
procedure (p.64).
On the [DWi-Fi on] screen,
select [Disconnect,exit].
If the [DWi-Fi on] screen is not

displayed, select [Wi-Fi function]
under the [53] tab.
Select [Disconnect,exit], then select

[OK] on the confirmation dialog to
terminate the connection.
