HORIZONTAL/VERTICAL KEYSTONE
To obtain maximum quality of the projected image, we recom- mend the installation of the projector on a level platform parallel and central to the screen.
Adjust the feet underneath to obtain a level position, lining up the base of the projected image to the base of the projection screen (Fig. 22).

The keystone adjustement helps to compensate possible ho- rizontal tilts of the projector.
LENS
The ZOOM adjustment impacts on the motorized zoom lens allowing to increase or decrease the dimension of the projected image. The FOCUS adjustment impacts on the motorized lens focus, allowing to obtain the highest definition on the projected image, an accurate focus setting should allow the viewer to di- stinguish each pixel that create the image one from another.
If the video signal used is not suitable for this purpose, the HT 500 LINK system provide two test pattern , each available with the ajustment mentioned above, in order to select the appropriate value for ZOOM and FOCUS.
This test pattern is displayed by pressing the • key, once the right adjustments are reached using the fl and ‡ keys, the test image can be easly removed pressing again the • key of the remote control. The LENS SHIFT adjustment allows to move horizontally (keys fl and ‡) and vertically (keys · and ‚) the lens, in order to center the image.
If the projected images needs to be centred, the LENS SHIFT (see next paragraph) adjustment allows the projected image to be moved vertically and horizontally, in relation to the centre of the screen (Fig. 23).

In the event you are unable to centre the image within the screen area, tilt the projector until the image is correctly positioned. Any keystone error can be removed by the Keystone adjustment in the Set up menu.

In the initial phase of installation the configurable keys (F1, F2) serve as optical zoom and optical focus (Fig.24).
LAMP POWER
If your room is especially dark, the images from the system HT500LINK could result execessively bright. In order to enjoy wonderful images, the ECOMODE function activation allows to re du ce the power used to feed the lamp. In this way, the bright- ness of the image will be adapted to your projection conditions
and a grater life lamp will be guaranteed.
POWER ON
If active (AUTO) allows to power up the system directly from the power feeder, once the initializing phase is completed.
