<Change time (Projector Usage Time)>
This function is used when changing the Projector Usage Time.
The action for the modification of the projector usage time should be carried out in the standby mode at all
times.
The present projector data are acquired and displayed on the screen.
The data acquired at the beginning (at the time of adjusting software start) are stored as the initial values and
displayed on the left of the arrow mark. The present values are displayed on the right of the arrow mark.
However, if ADJ Data Write is performed with [Data], the written data are stored as the initial values.
If it is necessary to change the Projector Usage Time, check the Change Time. Then, operation becomes
possible with the scroll bar, the [Set] button, and the [Reset] button.
Set up the proper time with the use of the scroll bar or by directly entering the time data into the time display
editor.
When the [Set] button is clicked, the projector usage time preset with the scroll bar/editor input is written in the
Flash ROM and displayed on the [Set] button.
When the [Reset] button is clicked, the projector usage time is restored to the initial values (those at the time
of adjusting software start) and written in the Flash ROM. Since then, the display on the [Set] button is
cleared.
After the Projector Usage Time has been changed ([Set] and [Reset]), pull out the AC cord of the PJ, without
fail, and confirm that the Power LED is unlit.

The default data setting of OSD display is carried out for the domestic (Japan) models (in Japanese) and the
overseas models (in English).
For the domestic (Japan) models, select [VTxxxJ Model].
For the overseas models, select [VTxxx, G, GS Model].
This setting is intended for the factory data only. Modification of user setting is not performed. (This is be-
cause of holding the user setting when ADJ data writing is effected with [Data].)
Note 1: In case of ADJ data Read/Write with [Data] during the replacement of the MAIN PWB, it is unneces-
sary to change the lamp, filter, panel,and projector usage time as well as the language since these
data have already been changed to the previous usage time.
Note 2: For the [Set]/[Reset] action of the lamp, filter, panel, and projector usage time, such operation should
be carried out in the standby state. In addition, these writing data cannot be written in the Flash ROM
unless the AC cord of the PJ is pulled out after the completion of [Set]/[Reset].
