2.1.3.5. Warning indication
C C h h a a n n g g e e r r can indicate a warning mark to induce to replace the spare lamp and a
pre-announcement of auto-lamp changing on screen. It can be set in WARNING menu in
INDICATION in the system menu (chapter 1.5.1.11, on page 40). Or you can also select no
indication setting.
[Warning mark to induce to replace the spare lamp]
"☀" mark is displayed on screen when a spare lamp is required to
replace after the auto-lamp changing (in other word, when spare lamp
status is "USED", "JUNK" or no attaching). It blinks once in 5 seconds.
The mark will disappear when the spare lamp is replaced to "NEW"
(new or not-deteriorated lamp). Even if the spare lamp status is not
"NEW", you can erase the indication by resetting the spare lamp
operating time (on page 77).
[Pre-announcement of auto-lamp changing]
The message appears when brightness deterioration is detected. The
auto-lamp changing starts after 5-minute displaying.
