2. 3. How to check the lamp runtime
The WARNING indicator will light in red when the lamp runtime (corresponding value) reaches 20 000 hours.
This is to indicate that lamp replacement is required. The lamp runtime is calculated by using the below formula.
The displayed time in [Lamp counter] = "Lamp runtime of [ (Normal)]" × 2 +"Lamp runtime of [ (Eco )]"
+ "Lamp runtime of [ (Quiet)]" × 2
When [Lamp control] is constantly set to [ (Normal)] without switching to other modes = 10 000 hours
When [Lamp control] is constantly set to [ (Eco)] without switching to other modes = 20 000 hours
When [Lamp control] is constantly set to [ (Quiet)] without switching to other modes = 10 000 hours
Follow the procedure below to check the lamp runtime:
1. Press and hold the <v
/b> button on the projector or the remote control for more than 20 seconds.
2. The projector runtime and lamp runtime will be displayed on the screen briefly as follows.
