Depending on the operation mode of the projector, changing the active lamp initiate different actions:
Cold Standby or Auto Switch mode
In this operation mode, the active lamp is on, the second lamp is switched off. Therefore when changing the
active lamp, the second lamp first has to be switched on (and the other lamp is switched off). Since a lamp re-
quires some time to burn stable, the displayed image will first have reduced brightness. After some instants the
image will show the former brightness.
In these operation modes, a subsequent change of the active lamp is only possible after the
cool down cycle of the first lamp (about 30sec).
Hot Standby mode
In this operation mode, both lamps are switched on. Therefore when changing the active lamp, there is no no-
ticeable impact on the displayed image (both lamp are adjusted to have the same brightness).
Since both lamps are one, a second subsequent change of the active lamp is immediately possible.
