To check to see if your connected to the Wireless Toast Network on your handheld device follow these simple steps.
First from the home page select the square on the bottom right corner with the dots.
Then select the option that says "Settings" it will look like a grey circular gear.
This then should bring you to the picture below.
Make sure the Connections tab at the top is selected and then the wifi option is turned on. From there select the appropiate network for your location and if it says "Connected" click on that network and check to make sure you have an IP address and that it matches the rest of the Toast equipment IP scheme. If you were installed by toast and your network is managed by toast, usually the IP scheme will be 192.168.192.xxx.
