automatically. For more detail, see "AUTO FOCUS" below.

AUTO FOCUS
The focus sensor on the projector detects the distance to the screen and automatically adjusts the focus of an
image.
• The AUTO FOCUS function will work when the following tasks are done:
- Turning on the power
- Changing the zoom lever
- Repositioning the projector
- Changing the projection angle
Effectve auto focus range for screen :3
Throw distance Image size (inch)
Tele (Zoom at min.) Wide (Zoom at max.)
Minimum distance 57.1"/1.5 m 33" 40"
Maximum distance 216.5"/5.5 m 123" 149"
When the throw distance is beyond 5.5 m/216.5", it means that the focus sensor will not work correctly and
that you need to use the FOCUS button to adjust the focus manually.
NOTE: In some cases, the AUTO FOCUS may not work correctly or the AUTO FOCUS range can be made narrower, de-
pending on the environmental conditions.
The AUTO FOCUS function will not work under the following circumstances
• When using a transparent screen.
• When there are objects between the focus sensor of the projector and the screen.
• When moving the projector so slowly that the focus sensor cannot detect the distance to the screen.
• When moving the screen, not the projector, because the focus sensor cannot detect the distance to the screen
TIP: To turn off the AUTO FOCUS function, from the menu select [SETUP] → [OPTIONS(1)] → [AUTO FOCUS] and select [OFF].
