Quick Reference Guide
Precautions for Use
This section describes precautions for using the machine. It also provides additional information about
the machine's specifications.
Where to use this machine
• The location in which the machine is used may affect the audio quality. Read the information
provided on p.17 "Installation Requirements" and select an appropriate location.
• This machine may not work properly depending on the network environment you are using.
For details, see p.17 "Installation Requirements".
Screen
• Do not remove the connected output cable to change the video output device after you turn
on the machine. Doing so can distort the screen image.
• Depending on the monitor used, the screen image may not be centered properly. If the
monitor is equipped with screen adjustment features, use these features to adjust the screen
image.
• If the machine is used in a poor network environment or the connection speed is slow, video
from a meeting or PC Screen Share may lag or even stop.
Meetings
• Because the automatic learning function of the echo canceller is active for approximately five
to ten seconds after a meeting starts, you may hear a loud noise or howling for a short time.
Although this noise greatly diminishes the audio quality and makes it difficult to hear the other
contacts, there is nothing wrong with the machine. The audio quality will gradually improve as
you continue the meeting and speak with the other parties.
• Depending on the status of the network band, video from you or the other contacts might not
be displayed. As a result, you will only be able to hear the voices of the other contacts
participating in the meeting.
PC Screen Share
• Sometimes PC Screen Share may not start automatically when you connect the machine to the
computer via a USB cable. If this is the case, the auto-play function on the computer might be
disabled. Check whether the function has been disabled. If it has been disabled, enable it. The
procedure for enabling and disabling the auto-play function differs depending on the
operating system version or edition you are using. For details, see the Windows Help.
