Appendix A: Performance Tips
Below are a few performance tips for getting the most from your Polycom CX5000 device.
Tips for audio performance
Review the following tips for getting the best audio quality during your phone session.
• Place the Polycom CX5000 device in the center of the meeting table. If your room is large,
consider seating the most active participants nearest to the device.
• Encourage attendees to speak in their normal voice. Speaking loudly or shouting may result in
uneven audio performance.
• Ask the people located at the remote site if they can hear you. Have them introduce themselves so
that you are certain to hear them.
• Because there may be a slight audio delay, you may need to pause briefly for others to answer or
make comments.
• Avoid rustling papers or tapping solid objects near the microphones.
Tips for video performance
Review the following tips for getting the best video quality for your conference.
• Place the Polycom CX5000 device in the center of the meeting table. If your room is large,
consider seating the most active participants nearest to the device.
• Distribute the lighting in your conference room evenly. Daylight is a variable light source and can
conflict with interior room lighting, so consider closing drapes or blinds.
• Because there is a slight delay in sending and receiving video signals, avoid rapid movements and
use natural gestures.
• When adjusting your Polycom CX5000 device prior to the meeting, try to populate the screen with
meeting participants rather than with the table, chairs, or walls.
• Ideal lighting would be a room with white fluorescent light.
• Echoes in a room degrade speaker detection for the device; avoid rooms that allow audio to echo
back.
• Have those presenting in the meeting talk directly towards the device. If their back is turned
towards the device, the sound capture is degraded.
