A. A/V Memory

Each of the external inputs has its’ own Audio/Video Memory. A change in an A/V setting at a specific input is stored in memory for that specific input.

B. A/V Reset

1.The front panel AV Reset (pressing the “Guide” and “Format” buttons at the same time) initializes all A/V Memories.

2.The AV Reset in the user’s menu initializes only the selected input’s A/V Memory.

LED Indicator Diagnostics

The front panel LEDs provide an indication of the sets operation, and the possible cause of a malfunction. There are three front panel LEDs, “Power”, “Status” and “Lamp”. Which LED is lit, the color and whether it is blinking or steady indicate the current status, or a possible malfunction.
