Setting up your Vantage Lite to Use with a Single Switch.
When you select 1 Switch as an access method, you see a screen that contains a number of ways to scan with one switch. Below are brief descriptions of the different methods.
Plug a single switch (or a dual switch using only the SELECT side) in either the SWITCH A or SWITCH B connector on the left side panel of your device.
If you are unsure how you want to use the 1 Switch method, we highly recommend that you try out the different 1-switch techniques to find the one that suits you best.
You can also use the PRC Bluetooth Switch for 1-switch scanning. See the directions that came with your switch.

1 Switch Scanning Options
Scanning Speed
This is the amount of time it takes for your device to move from one key, row, or column to the next in a scan. The default scanning speed is one second. This means it takes one second from the time one key is highlighted until the next key is highlighted.
Acceptance Time
The amount of time you must maintain contact with your switch before the key you have scanned to is accepted. The device beeps when your key is accepted. For example, if you set acceptance time for .50 seconds, you must activate and hold your switch for ½ second before the key will be selected and the device beeps.
Note: if you are using a 1 switch scanning selection that includes hold, the acceptance time will begin when you release your switch.
Release Time
This tells your device how long to wait after you release your switch before you can make another activation with the same key or switch. For example, if you set the Release Time for 1 second, you must wait one second after you release your switch before you can continue to scan or activate your switch. If you release your switch and then accidentally activate it again before the release time has passed, your device will not make any activations.
Auto Repeat
This lets you choose how fast a key will repeat when you hold it down.
Activation Delay
This gives you a few seconds to change your mind when you have selected a key. This is automatically set to your Scanning Speed. For example, let’s say your scanning speed is set to one second (1.0). You scan to and select a key, then realize it’s not the key you want. You have one second to activate your switch again to “de-select” the key and then scan to a new key.
Scan Auto Restart
When this is On, a new scan will automatically start once you have made a key selection. If it is Off, you must activate your switch to start a new scan.
Number of Rescans
Select the number of times you want your device to automatically scan the overlay. The default is 3 times, then the scan will stop until you activate a switch to start it again.
Use Screen as Switch
This tells the device to let you use the display screen as a switch. Tap the screen to make selections. This option does not work in the Toolbox.
Modify Scan Pattern
This allows you to make changes to the default scan pattern. You can select the Preview key on this menu screen and see the scan move as you create it. You may want to use this option for selected Pages, especially with Scenes. .
Predictive Selection
This works hand-in-hand with Icon Prediction. (Icon Prediction is in the FEEDBACK MENU and the default is ON.)
When you turn Predictive Selection On, your device highlights only those icons where messages are stored. These highlighted icons are the only keys on the keyboard that will produce a response.
You can change the color of the non-active keys to grey or white. Go to the FEEDBACK MENU, Icon Prediction and select Grey or White. Grey allows you to see the shadow of the icon on the key; white turns the entire key white so it looks blank. But if you try to select a grey or white key, nothing will happen.
Note: Icon Prediction alone allows you to press grey or white keys. The key’s icon will appear in the Icon display area but no message will be spoken. Icon Prediction will work whether Predictive Selection is On or not.
