Step #1: Record Your Current Device Settings

The device setup tool is available on each device running Toast. The settings are device-specific and can only be edited from the device itself. 


It's important that your new Toast Flex is set up identically to your current device. To make sure that's the case, take some time to download and fill out this form here.


To access the Device Setup screen on your device, navigate to the main menu of the Toast app, scroll down and select Device Setup under the Setup header.

Step #2: Unplug & Uninstall Your Current Hardware

Next, go ahead and uninstall your current Toast Flex by following these steps:
 

  1. First, power off your Flex terminal and unplug the power adapter from the wall outlet. If your Flex is plugged into a Toast Printer/Hub, make sure to unplug the power adapter for the Toast Printer from the wall outlet. 
  2. Remove the power plug (orange) from the bottom of the terminal and make sure to unscrew the thumbscrew and remove the cable. 
  3. If you have an Ethernet cable (yellow), please disconnect it from the terminal. (Note: Keep all ethernet and power cables handy for your new terminal.)
  4. If you're using your existing card reader, disconnect it and unscrew it from the terminal. If your card reader is attached to your Toast Printer/Hub, there is no need to unplug it. 
  5. If you have a Flex for Guest with a wedge (on-counter) Guest-Facing Display, go ahead and disconnect the Guest-Facing Display from the Flex.

  1. Gently flip and place your Flex terminal so that the display faces down and you can access the thumbscrews on the back. Unscrew the two thumbscrews and lift up to remove the backplate. 
  2. Unplug the green (GFD) (Guest Facing Display) and blue (HDMI) (High-Definition Multimedia Interface) cables and remove this cable from the terminal by guiding it back through the stand or leaving it. Note that there may not be any cables plugged in. If nothing is plugged into the green and blue ports, move on to step 3.
