• 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 LE-Series 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 cannot cali-

brate wide angle.)

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

4. Tap Calibrate. A block of text appears.

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

microphone because the audio system filters out many

unwanted sounds. If you are dictating in an office or recording during

a meeting, the audio system may work well with no

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.

Enabling speech recognition enrollment. It is necessary to train the system to

your voice before you can use the Speech Dictation and Voice Command

capabilities of the Tablet PC. The procedure is used to adjust the microphones and

train the Tablet PC for the characteristics of your voice. The entire process takes

about 10 minutes. It is advisable to move to a quiet environment before starting this

procedure.

1. Open the Motion Dashboard and make sure the speakers and

microphone are turned on (the default settings).
