How do I Scan Using a Single Switch?
1-Switch—Scan Mode 1
Summary: Plug a single switch or a dual switch (use only the SELECT side of a dual switch) into one of the SWITCH jacks on the side of the case. The default scan is Automatic and the scanning rate is 1 second. You can also choose to use the display screen as a switch.
To Scan in 1-Switch Scan Mode 1:
Activate your switch (or tap the screen if you selected Use screen as switch) to start the scan. If you are using Row/Column scan, the top row on the keyboard lights, then the second row lights, etc. Each time a row lights, you hear a beep. When the row you want lights, activate your switch or tap the screen to select the row.
The scan moves from left to right through the columns in the row. When the key you want lights up, activate your switch or tap the screen to select that key. If a message is stored in the location you have selected and the speech is turned On, the device speaks the message and then returns to scanning down the rows.
If you do not make any switch activations after starting a scan, your device automatically scans the rows or the columns three times and then stops scanning altogether. To begin another scan you must activate your switch.
To Change the Settings to 1 Switch Scanning: Activate the TOOLS button on the case to go to the Toolbox screen. Activate SELECTION TECHNIQUE MENU. Select 1-Switch in the Selection Technique box. Other functions can be adjusted to suit the users needs, such as the scanning speed, acceptance time and release time.
To Scan Using 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 either activate your switch to move to the next key, or you can wait until the Acceptance Time passes and your device will automatically select the first key in the row. Press your switch to start a new scan.
1-Switch—Scan Mode 2
Summary: Scan Mode 2 is another single switch scanning technique. This technique involves four switch activations instead of three as in Scan Mode 1. You can select this style in the Toolbox. You cannot use this technique with an 8 or 4 location keyboard.
To Change the Settings to Scan Mode 2: Activate the TOOLS button on the case to go to the Toolbox screen. Activate SELECTION TECHNIQUE MENU. Select 1-Switch in the Selection Technique box, and then select the Scan Mode 2 option.
To Scan:
The first switch activation causes the top row to light. The scan continues automatically down the rows. When it reaches the row you want, activate and release your switch. The scan stops at the row you have chosen and Column 1 is scanned. Press the switch again and the scan proceeds across the row. When the scan reaches the key you want, press the switch to activate the location.
To Scan Using 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. Your device will beep and highlight the first key in the row. Activate your switch to select the key. Activate your switch twice to step to a different key in the row.
