• Wide Angle — Widest angle of acceptance. Try starting with this
setting (even for dictation) before using a more restricted angle.
Change to the Narrow or Medium Angle to eliminate more
background noise.
1 Narrow Angle; 2 Medium Angle; 3 Wide Angle; 4 Microphones (only two of
the three microphones are shown in this illustration of the LE1600 Tablet
PC).
• Skew angle. The pre-set sound detection area is straight in front of
the system display. If you want the system to receive sound from
elsewhere, you can skew the receiving direction towards one or the
other microphone (keeping the same relative angle of acceptance.
Setting up the skew angle for calibration:
1. On the Audio panel, open the Motion Dashboard.
2. Under Microphone, tap Narrow Angle or Medium Angle. (You can-

3. Move to where you want the microphone to detect your voice.

5. Read the text aloud, speaking normally towards the Tablet PC micro-
phones. This should take 20-40 seconds.
NOTE: In many cases, you will not need to calibrate the

additional calibration.
IMPORTANT: The audio system does not store calibrations. If
you change to another angle/position and then return to the
previous one, you must re-calibrate the audio system.
