 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.
