Setting up your 2 Switch Scanning Method in the Vantage Lite.
Plug two single switches or a dual switch into either the SWITCH A and/or SWITCH B connectors on the left side 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.
2 Switch Step Scan, Row/Column
You must activate your switch each time you want to move to a new position on the keyboard. Rows are scanned first, then columns.
2 Switch Step Scan, Column/Row
You must activate your switch each time you want to move to a new position on the keyboard. Columns are scanned first, then Rows.
2 Switch Step Scan, Quarter Row/Column
The scan divides the overlay into quarters. When the scan reaches the quarter you want, activate your switch. The rows or columns in that quarter are scanned. Select the row or column you want. Individual keys are then scanned. Select the key you want.
2 Switch Step Scan, Quarter Column/Row:
The scan divides the overlay into quarters. When the scan reaches the quarter you want, activate your switch. The rows or columns in that quarter are scanned. Select the row or column you want. Individual keys are then scanned. Select the key you want.
2 Switch Step Scan, Linear
This allows you to step through the keys on your overlay moving from left to right across the rows or from top to bottom down each column. You must activate your switch to move the scan.
2 Switch Auto Scan, Directed
Your device automatically scans the keyboard. Change directions by activating your switch.
2 Switch Hold Scan, Directed
You must press and hold your switch to scan the keyboard. Change directions by releasing and then pressing and holding your switch.
Note: At this time directed scans will not allow you to scan the Word Prediction list.
2 Switch Scanning Options
Cancel Time
If you are in the middle of a scan, get distracted, and forget to activate your switch to make a selection, the scan will stop and the highlighting will disappear after the Cancel Time has passed. If you need a lot of time between switch activations, you can set the Cancel Time to a very long time before the scan stops.
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.
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.
Scan 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.
Number of Rescans
Select the amount of times you want to scan the overlay.
Selection Type: Manual/Auto
If you select Manual, you must have a third switch plugged into your device. You will use this switch to make your final selection.
If you select Auto, your device will automatically select the key you have scanned to after the Acceptance Time has passed.
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.
Predictive Selection
This option 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.
Note: Icon Prediction will work whether Predictive Selection is On or not.
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.
