How do I Scan Using a Single Switch?
1-Switch-Scan Mode 1
Summary: 1-switch-Scan Mode 1 is a single switch scan mode that requires 3 switch hits to make a selection when set to Row/Column scanning. The default scan is Automatic and the scanning rate is 1 second. You can also choose to use the display screen as a single switch.
Open the SELECTION TECHNIQUE MENU. In the Selection Technique option, select 1-Switch. Select More Items until you see the Scan Mode option. Select Scan Mode 1.
To Scan in 1-Switch Scan Mode 1:
Activate your switch to start the scan. If you are using Row/Column scan, the top row on the keyboard lights, then the second row, then the third, etc. Each time a row lights, you hear a beep. When the row you want is lit, activate your switch or tap the display screen to select that row. The scan then moves from left to right across 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, your device will speak the message, then return to scanning down the rows.
If you do not make any activations after starting a scan, your device automatically scans the keyboard 3 times and then stops scanning. To begin another scan, activate your switch or tap the display.
NOTE: You can select the amount of rescans you want in the Number of Rescans option.
1-Switch-Scan Mode 2
Summary: 1-Switch-Scan Mode 2 involves 4 switch activations instead of 3. Scan Mode 2 is another single switch technique.
Open the SELECTION TECHNIQUE MENU. In the Selection Technique option, select 1-Switch. Select More Items until you see the Scan Mode option. Select Scan Mode 2.
To Scan in 1 Switch Scan Mode 2:
For Row/Column Scan: Activate your switch. The top row on the keyboard lights. The scan automatically continues down the rows. When it reaches the row you want, activate and release your switch. The scan stops at the row you have chosen. Press the switch again and the scan proceeds automatically across the row. When the scan reaches the key you want, activate your switch to select the location.
NOTE: If you prefer Column/Row scan, columns will be chosen first, then the row.
