Protection Mode
The 4305P system is provided with different levels of protection, in the rare event that the system
detects and internal malfunction, it will be represented by the selected Source icon to illuminate
solid Red color. The system will remain in that state for as long as the protection event is present.
(The example to the right, an issue has resulted while the Optical input was selected.)

• Software upgrades are automatic, as long as the system is connected to an active network.
• If a valid update is available, the unit will automatically start the update process which will be
indicated by the Power LEDs to illuminate and flash Purple in color.
• When completed, the Power LEDs will return to previous status and normal operation will
resume.
