LAMP SELECT "LAMP SELECT" is used to choose from "SINGLE" and "DUAL" modes depending on user's needs or viewing conditions. In "SINGLE" mode, the projector may automatically select either lamp from the 2 lamps, or the particular lamp can be specified. DUAL : Two lamps are used simultaneously. SINGLE : One of either lamps is used (lamp with shorter operating hours is automatically selected). LAMP1 : Lamp Unit 1 is always used. LAMP2 : Lamp Unit 2 is always used. When one of the above settings is selected, it will take effect after the ENTER button is pressed. Note • If, in the "SINGLE", "LAMP1" or "LAMP2" mode, one lamp remains off or the currently active lamp exceeds 3 000 hours of cumulative operating time, the other lamp will light. If, in the "DUAL" mode, one lamp remains off or the currently active lamp exceeds 3 000 hours of cumulative operating time, the other lamp alone will light. However, if both lamps remain off or the 3 000 hours of cumulative operating time are exceeded, the projector will enter the standby mode. • The colors of the items indicate the status. Green Current setting Yellow Current setting (when a lamp fails or fails to light) Red Lamp that has failed to light White Any other status • If the projector is repeatedly used for short periods of time, the lamps will need to be replaced more frequently. LAMP RELAY If using the projector for a continuous period of 24 hours or more, this setting can be used to automatically switch the lamps that are turned on in order to reduce the lamp deterioration that can occur as a result of continuous use. OFF : This is the standard setting. "LAMP RELAY" is disabled. 00:00 - 23:00 : This can be set in one hour intervals from 00:00 to 23:00. Note • Only when "DUAL" or "SINGLE" is selected in "LAMP SELECT", "LAMP RELAY" is active. If "LAMP1" or "LAMP2" is selected, "LAMP RELAY" function is not available. • When "DUAL" is selected in "LAMP SELECT", only one lamp will light for a 4-hour period after the set time. • When "SINGLE" is selected in "LAMP SELECT", the lamp that was off at the set time will light, and then the lamp that was lighted until the set time will turn off. • The setting time will be the local time.
