1. Sensitivity adjustment
If the Braille Sense U2 QWERTY cannot tune to the broadcast frequency
you desire, adjust the scanning sensitivity. To adjust the sensitivity, open the
"Settings" dialog as described in Section 10.1. Press “down arrow button” to
navigate to "Sensitivity" and press "Space" or "Backspace" to adjust the
sensitivity. Higher values increase the scanning sensitivity of the radio. If the
sensitivity is increased, you can fine tune to more frequencies.
2. Mute
While listening to the radio, press "Space" to mute the audio. Pressing
"Space" once again unmutes the radio. You can also mute the radio by
pressing the "stop" button on the front panel, and unmute by pressing the
"play" button. If mute is activated, the radio is silent, but TTS (text to speech)
and all other system sounds are heard.
