When to replace the lamp unit

replace the lamp unit regularly.
Please refer to the displayed time in [Lamp counter] of [Info.] about the usage time of lamp .
The estimated duration before replacement is 6 000 hours which is displayed in [Lamp counter], but the lamp may
go off before the time above mentioned has elapsed depending on individual lamp characteristics, usage conditions,
and the installation environment. It is recommended that the Replacement lamp unit be prepared earlier.
The time which is displayed in [Lamp counter] is a total time when the real usage time in [ (Normal)], [ (Eco 1)]
or [ (Eco 2)] is converted to the runtime in [ (Eco 1)]. Please note that they are not displayed individually.
The displayed time in [Lamp counter] = "Lamp runtime of [ (Normal)]" × 1.2 +"Lamp runtime of [ (Eco 1)]"
+ "Lamp runtime of [ (Eco 2)]" × 0.6
The real usage time when the displayed time in [Lamp counter] is 6 000 hours means,
When [Lamp control] is constantly set to [ (Normal)] without switching to other modes = 5 000 hours
When [Lamp control] is constantly set to [ (Eco 1)] without switching to other modes = 6 000 hours
When [Lamp control] is constantly set to [ (Eco 2)] without switching to other modes = 10 000 hours
If you continue to use the lamp unit after the displayed time in Lamp counter 6 600 hours has elapsed, the lamp
