Backlit Button Indicator

The Cisco Video Door Station button's light can be turned on or off depending on what is required for
the installation.
The backlit button may make it easier to see the button when it is dark outside. Normally, the light on
the button remains on or off depending on how it is configured in the system, however, it is also used to
convey device status during certain times.
When the device is first powered on, the button will blink slowly until the device is ready to be used in
the system. If the button continues to blink slowly for over 3 minutes, then the device may be
experiencing a problem and should be factory restored. During a factory restore process the button will
blink rapidly.
