From your frame

Press the Menu button and navigate to Settings > Slideshow Settings > Slideshow Timing and adjust the Photo Interval setting.

Making your CEIVA slideshow faster or slower

Your slideshow will change photos every five seconds by default, but you can change this time to be slower so you can enjoy your photos longer by adjusting the Photo Interval setting.

You can change this time in the settings of your frame on the My Frames page in your ceiva.com account or on your CEIVA frame.

* CEIVA 1™, CEIVA 2™, and CEIVA 3™ models do not have the Slideshow Timing Menu.
