Setting up 2 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.
Dual or 2-Switch Scanning use a dual switch or two single switches to scan left, right, up and down to any key on the keyboard. Plug two single switches or a dual switch into either the SWITCH A and/or SWITCH B jacks on the connector module.
You can also use the PRC Bluetooth Switch for 2-switch scanning. See the directions that came with your Bluetooth Switch.
To Change Access Methods to 2 Switch Scanning:
1. Go to the Toolbox to Access Method Menu
2. Select Choose Different Access Method 
3. Select 2 Switch 
4. Now you see many 2 switch scanning options. Select the one you wish to use. Below are descriptions of the scanning methods.
5. Adjust the scanning settings to fit your needs.
Descriptions of Scanning Methods
Auto Scan Directed
Your device automatically scans the keyboard. Change directions by activating your 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.
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 and you select to have an extra hit at the end of your selections.
Adjusting your Scanning Settings:
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.
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.
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.
