Setting up 1 Switch Scanning in Accent
An Access Method is the method you use to control your device—touch, switch, etc.
You select an access method, then you customize that method for your personal use by selecting the options you want.
TIP: 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.
1-Switch Scanning MethodsUse a single switch to scan to any key on the screen. Choose to scan by rows and columns or by columns and rows. Plug a single switch (or a dual switch using only the SELECT side) into either the SWITCH A or SWITCH B jack on your connector module.
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 technique terms.
Changing to a 1 Switch Scanning Method:
1. From the Toolbox, select Access Method Menu
2. Select Choose Different Access Method 
3. Next select 1 Switch 
4. Now you will see all the different Scanning Options. Choose the one you wish to use. Descriptions of these methods are listed below.
5. Change the settings to fit your needs.
Your device automatically scans the keyboard.
Hold Scan
You must press and hold your switch to scan the keyboard.
Step Scan
You must activate your switch each time you want to move to a new position on the keyboard.
Linear Scan
This allows you to step through the keys on your MAP 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.
Row/Column
The scan highlights each row of keys beginning with the top row and moving down the screen. When the row that contains the key you want is highlighted, activate your switch. The scan will highlight the separate columns in the row you selected, moving from left to right across the screen. When the key you want is highlighted, activate your switch. The device beeps when your key is accepted.
Column/Row
The scan highlights the columns first instead of the rows, moving from left to right across the screen. When the scan reaches the column that contains the key you want, activate your switch. The scan begins to highlight each key in that row. When the key you want is highlighted, activate your switch. The device beeps when your key is accepted.
Quarter Row/Column
Quarter Column/Row
The scan divides the MAP 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. You can select Auto, Hold or Step to scan.
Adjusting the Scanning Settings:
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.
This is the amount of time it takes for your device to accept a location you have selected and to select the key. The device beeps when your key is accepted. For example, if you set acceptance time for .50 seconds, you must touch the key or 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 method that includes hold, the acceptance time will begin when you release your switch.
This is the amount of time it takes you to release a key and be able to select another key. For example, if you set this for 1 second, you must wait one second after you stop touching a key or release your switch before you can select the same key or a new key.
This lets you choose how fast a key will repeat itself when you hold it down.
When Predictive Selection is On, keys that do not produce messages are turned off. If you touch or scan to them, nothing will happen. Only keys that contain or are part of actual stored messages will work.
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.
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.
Select the number of times you want your device to automatically scan your MAP. The default is 3 times, then the scan will stop until you activate a switch to start it again.
This tells the device to let you use the display screen as a switch. Tap the screen to make selections. NOTE: This option does not work in the Toolbox.
See the Bluetooth Switch and adapter mini-manual for complete information. Once you have your access method options selected, set the Bluetooth switch to the default Switch Mode; plug in an extra switch if you need one; select Bluetooth Switch in the ACCESS METHOD MENU. Press the PAIR button on the Bluetooth Switch, then select the Pair with Switch Button on your device screen. You will see a box on your device screen telling you when the pairing is complete and the device and switch are connected
