Quick Reference Guide

• Do not use this machine when it is improperly positioned or oriented. Doing so may lead to failure
or shorten the product life.
• Route and position the power cord and other cables so that other users do not trip over them.
Tripping over the cables may cause the machine to fall, resulting in personal injury.
Preventing the deterioration of sound quality
• Keep objects that may cause the sound quality to deteriorate away from the microphone or
speaker.
• Blocking both the microphone and speaker may cause the sound quality to deteriorate.
• Do not place devices that generate noise, such as projectors or computers, near the machine.
• When using the machine in a room where sound echoes, try keeping your voice as low as
possible during meetings to avoid distracting echoes.
• Make sure there is sufficient space between this machine and the wall.
• Keep this machine away enough from the other party's device, for example, when the other
party's voice can be heard directly instead of through a speaker.
• Do not move the machine during a meeting.
• If you plan to use an external microphone and speaker, see the manual for details about how
to use the device.
• When using an external microphone speaker, keep it away from the air outlet of the machine.
Placing an external microphone speaker too close to the air outlet can cause the audio quality
to deteriorate.
About network environment
• A poor network environment can cause delays in video streaming during meetings.
• When using a wireless network, communication quality may deteriorate or communication
may be lost, depending on the environment in which the machine is used. If these problems
occur, use a wired network instead. To switch to a wired network, you must first turn the
machine off and then turn it back on.
• When using a wireless network, radio or electromagnetic interference or weak reception may
cause the following problems to occur during meetings:
• Delays in video streaming.
• Video is stopped.
• Audio of other party cuts out.
• Synchronization between video and audio is lost.
• Audio quality deteriorates.
• Meetings are automatically ended or left.
• Delays in video streaming occur when sharing computer screen.
• Your video and the other party’s video disappear and only audio is heard.
