Tip
Presentation devices automatically shut off when there is no longer a video signal to that presentation device. An
on-screen timer counts down the remaining time to shut-down. The amount of time that it takes a device to shut down
depends on your Cisco Unified CM configuration. Most CTS devices that support
PiP
shut down in 10 to 15 seconds
after the video signal is removed. Devices on the CTS 3000 and CTS 3200 series that have black boxes associated
with the auxiliary control take 5 minutes to shut down. See the Product Specific Configuration Layout section of the
Cisco Unified Communications Manager Configuration Guide for the Cisco TelePresence System
for more
information about controlling presentation devices and associated displays.
