How do I Adjust Additional Settings in the Selection Technique Menu?
Selection Technique Menu Basics:
Scanning Speed: Scanning speed is the amount of time it takes the device to move from one key to the next in a scan. As the device scans, it beeps and highlights each key.
Acceptance Time: Keyboard: the amount of time you must maintain contact with a switch before the device accepts a location and makes a key activation. Headpointing: the amount of time it takes between the time the key is pointed to and the time the device accepts the location and activates the key.
Release Time: The amount of time it takes for you to release a key and be able to activate another key or start a new scan.
Activation Delay: when this is turned On, you can scan to a key, select it and then change your mind and begin to scan again before the key is activated. Activation delay is automatically set to your scanning speed.
Auto Repeat Rate: Select a key, hold it down and it will repeat automatically at the speed you have set.
Predictive Selection: Predictive Selection (and Icon Prediction in the FEEDBACK MENU) will be visible only when you are using an overlay that requires two or more activations to recall a message. When Predictive Selection (and Icon Prediction) are both On, only those keys where messages are stored are active.
Scan Direction:
Row/Column: the scan starts by highlighting the top row of keys. It moves down by rows. When the row that contains the key you want is highlighted, activate your switch. The scan highlights the separate columns in the row you selected. The scan moves from left to right. When the key you want is highlighted, activate your switch. The key is selected.
Column/Row: the scan begins by scanning the columns instead of the rows. The scan moves from left to right across the columns. When the scan reaches the column that contains the key you want, activate your switch. The scan highlights each key in that row. When the key you want is highlighted, activate your switch. Column/Row is not available with 2-Switch Scan Mode 1.
Linear: allows you to step through the keys on the overlay moving from left to right across the rows or from top to bottom down each column.
Step: Activate your switch to highlight the top row. Activate your switch each time you want to step to a new row. When you reach the row that has the key in it that you want, wait for your switch Acceptance Time to pass. The device will beep and highlight the first key in the row. You can activate your switch to move to the next key, or you can wait until the Acceptance Time passes and the device will automatically select the first key in the row. Press your switch to start a new scan.
8 and 4 Location Scans: the choices are circular, linear or row/column . Use Step or Auto for switch activation. If you select Step you must activate your switch each time you want to move to a new row or key. If you select Auto the keys are scanned automatically. Activate your switch to select a key. Two switches may be used, one to step scan and one to activate.
Some Other Options in SELECTION TECHNIQUE MENU:
Scan Top Row: The scan will include the Activity Row either before or after the core vocabulary (First or Last). Off = no scan of top row.
Scan Type: The options for Scan Type include Auto or Hold and Step. Auto means that the device automatically scans the keyboard. Hold means that you must press and hold your switch to scan the keyboard. Step means that you must press your switch each time you want to step to a new position.
Selection Type: (Scanning) Choose to select a location either automatically (Auto) or manually (Manual). Auto means that the device automatically selects a location after the acceptance time has passed. Manual means that you must activate your switch to select a location. Use this with 2-switch or a joystick..
Scan Auto Restart: If this is Off, once you have selected a message, you must activate your switch to start a new scan. If this is On, once you have selected a message, the device automatically starts a new scan.
Number of Rescans: This allows you to select the number of times you want the device to automatically re-scan the keyboard. You can select a number from 0 through 10. The default is 3 times.
Auto Repeat Rate: Lets you choose how fast a key will repeat itself if you hold it (or your switch) down. If you select 1.0 for example, the key repeats itself once a second.
Activate Key When: Allows you to tell the device to activate a key when you touch or push the key or when you release the key. The default is Pushed. NOTE: If you set this to Released you will not be able to store any new recorded messages.
