receiver enters the receive mode automatically after it wakes up.
• When communication is with a computer (USB selected as the cable type), connecting the
USB cable to a computer and then to the calculator (while the calculator is turned off) will
cause the calculator to turn on and the “Select Connection Mode” dialog box to appear.
