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		Memory Timing
Operation in Normal Operating		•	Approximately four seconds after the end of the operation
Mode		•	When entering the STANDBY status through remote operation, through the operating panel
• Power switch On/Off			of the main unit, or by issuing a <POF> command.
• Input switchover		• When switched to Menu mode as a result of a MENU button action
•	Changing of screen size	• When switched to RS-232C adjustment mode by an <AJY> command
		(NOTE) Among the RS-232C commands available in Normal Operating mode, some are not stored in
•	Volume adjustment/muting
			last memory when used in this mode.
• Setting of KEY LOCK/UNLOCK
			See 5.5.1, “About the RS-232C Adjustment Mode”.
Adjustments and settings in		•	Approximately four seconds after the end of the operation
menu mode		• When entering the STANDBY status through remote operation, through the operating panel
			of the main unit, or by issuing a <POF> command
		•	When returning to the previous screen with the SET button
		•	When exiting Menu mode with the MENU button (restoring the unit to Normal Operating
			mode)
		• When exiting Menu mode with the KEY LOCK/UNLOCK button (switching unit to Normal
			Operating mode and entering the KEY LOCK status)
		• When switching to RS-232C adjustment mode with an <AJY> command
		• When switching over to another input signal mode (i.e., to another signal frequency) (restoring
			the unit to Normal Operating mode)
		• When automatically exiting Menu mode after persistence of no-signal status for approximately
			eight minutes (restoring the unit to Normal operating mode)
Adjustments and settings in		•	Approximately four seconds after the end of the operation
Integrator mode		•	When entering the STANDBY status through remote operation, through the operating panel
			of the main unit, or by issuing a <POF> command
		•	When returning to the previous screen with the SET button
		• When exiting Integrator mode with the MENU button (restoring the unit to Normal Operating
			mode)
		• When exiting Integrator mode with the KEY LOCK/UNLOCK button (switching unit to Normal
			Operating mode and entering the KEY LOCK status)
		• When switching to RS-232C adjustment mode with an <AJY> command
		•	When switching over to another input signal (i.e., to another signal frequency) (restoring the
			unit to Normal Operating mode)
		• When automatically exiting Integrator mode after persistence of no-signal status for
			approximately three minutes (restoring the unit to Normal operating mode)
Adjustments and settings in RS-		•	Approximately four seconds after the end of the operation
232C adjustment mode		•	When entering the STANDBY status through remote operation, through the operating panel
			of the main unit, or by issuing a <POF> command
		• When changing adjustment or setting items using PC commands
		• When exiting the RS-232C adjustment mode with an <AJY> command (restoring the unit to
			Normal Operating mode)
		• When exiting RS-232C adjustment mode with the KEY LOCK/UNLOCK button (switching
			unit to Normal Operating mode and entering the KEY LOCK or KEY/UNLOCK status)
		• When switching to the Menu mode with the MENU button

(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”.
