METHOD OF ADJUSTMENTS
<Change time (Filter Usage Time)>
This function is used when changing the filter usage time.
The action for the modification of the filter usage time should be carried out while the PJ power supply is
made to stay in the Standby mode.
At the beginning (at the time of adjusting software start), the projector data are acquired and stored as the
initial values.
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 Filter Usage Time, check the Change Time. Then the usage time is displayed
as "0 Hours." At that time, 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 filter 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 filter 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.
Upon the completion of changing the filter usage time ([Set] and [Reset]), pull out the AC cord of the PJ
without fail and confirm that the Power LED is unlit.
When changing the Filter Usage Time to "0 Hours," use the ON-screen menu in the serviceman mode. Then,
clearing becomes possible.
