Using the microphone
Your computer has a built-in microphone that can be used to record
monaural sounds into your applications. It can also be used to issue voice
commands to applications that support such functions.
Since your computer has a built-in microphone and speakers, “howling”
may be heard under certain conditions. Howling occurs when sound from
the speaker is picked up in the microphone and amplified back to the
speaker, which amplifies it again to the microphone.
This howling occurs repeatedly and causes a very loud, high-pitched noise.
It is a common phenomenon that occurs in any sound system when the
microphone input is output to the speaker (throughput) and the speaker
volume is too loud or too close to the microphone. You can control
throughput by adjusting the volume of your speaker or through the Mute
function.
To adjust the volume or activate Mute, click start, point to All Programs,
point to Accessories, point to Entertainment and click Volume control.
In the
Master volume
panel, you can use the slide bars to adjust the
volume level or click Mute at the bottom of the panel.
■ WinDVR must be installed using the Administrator account.
■ When two sequential scheduled recording sessions have been
reserved, the first session will terminate about 2 minutes before the
specified end time. This is because the second session needs a time
for preparation (For example, if two recording sessions of 1:00-2:00pm
and 2:00-3:00pm have been booked, the 1:00-2:00pm session will
terminate about 2 minutes earlier, that is, at about 1:58pm).
■ When you have set a password for the user account, scheduled
recording cannot be performed if Standby Mode is activated.
■ Even if you click the Stop Auto Scan button, the scan may not be
stopped due to the timing of processing. In that case, click the button
repeatedly.
■ If you exit WinDVR one minute or less before the scheduled recording
starts, recording may not be performed correctly. Therefore, do not
close WinDVR during a period of one minute before the scheduled
recording start time.
■ When video is imported from a video deck or other devices, noise may
appear in the top or bottom part of the screen. This noise is due to the
display areas called vertical blanking intervals, and not a failure.
