If you press “Enter” without typing in any numbers, the “Countdown 
timer” will start with the default, which is set to one minute. When started, 
the “Countdown timer” will display “count down xx minute,” and it will 
start running. If you press “Enter” in the “Countdown timer,” the Braille 
Sense U2 will tell you the remaining time, and then it will pause. If you 
press “Enter” again, it will restart. Pressing “Backspace” will clear the 
“Countdown timer.” If the timer reaches zero, you will hear a 10-second 
alarm, and the “Countdown timer” will clear. If you press “Backspace-
enter” while the alarm is sounding, the alarm will stop and your timer will 
clear, and will be ready to accept a new time. 
If you press “tab (Space-4-5)” or “shift-tab (Space-1-2)” again anywhere 
in the count down timer, the stopwatch will be ready. If you want to exit 
the “Stopwatch” or “Countdown timer,” press “Space-z (dots 1-3-5-6)” 
anywhere within the “Stopwatch” or “Countdown timer,” and you will 
return to the “Stopwatch” menu. 
17.9 Terminal for Screen reader
The “Terminal for screen reader” function allows the Braille Sense U2 to 
be used as a Braille display when hooked up to a computer that uses a 
compatible screen reader such as Window-Eyes or Supernova Window-
Eyes, Supernova or JAWS. Before using this function, make sure that 
the Braille Sense U2 is connected to your personal computer via a 
Bluetooth serial or to the USB client port. To turn on this function, go to 
the “Utilities” menu, and press “Enter.” Then, press “Space-4,” until you 
hear “Terminal for screen reader.” Then, press “Enter.” If you activate 
“terminal for screen reader,” you will see the list of connection methods. 
In the list, you will see “Bluetooth serial port” and “USB port.” Press 
“Space-1” or “Space-4” until you reach what you want to select. If you 
have selected one, press “Enter” and you will hear “terminal mode.” The 
Braille Sense U2 will no longer say anything, as it is now simply acting 
as a Braille display for your computer. If you fail to connect, you will be 
returned to the list of connection methods.
