Last Memory; Aging - Pioneer PDP-433CMX Technical Manual

Before Beginning Adjustments

5.1.5 Last Memory

The last memory timing used by the unit is given in the table below.
Remember, no last memory function is executed if you perform the following without meeting these timing requirements:
• Switch off MAIN POWER;
• Unplug the power;
• Switch off the outlet.
Item
Operation in Normal Operating
Mode
• Power switch On/Off
• Input switchover
• Changing of screen size
• Volume adjustment
• Setting of KEY LOCK/UNLOCK
Adjustments and settings in
menu mode
Adjustments and settings in
Integrator mode
Adjustments and settings in
RS-232C adjustment mode
(NOTE) If you start or stop the entire system by switching a breaker on or off, allow enough time for the last memory
function to be performed by satisfying the timing requirements given above.
Note that this practice causes count errors on the hour meter.

5.1.6 Aging

After switching on power to the unit, input signals to perform aging until the unit stabilizes. Use signals that are unlikely
to cause the displayed images to be "burned" onto the screen: signals such as a 100 % white signal, or animation from
LDs are recommended. The process should take about 30 minutes. This ensures precision adjustments.
(NOTE) Display of still images over extended periods can lead to the above-mentioned "burning".
