Ultra short throw (UST) lens installation
The ultra short throw (UST) lens enables large screen projection from a short distance, which significantly
increases the flexibility of projector installation. This installation guide provides detailed steps on mounting
the UST lens to your projector. Before the installation, please read through this guide in full to ensure the
installation steps are made correctly.
Safety precautions
•Installation and adjustments should be performed by qualified Technicians or authorized service
dealers.
•Make sure the projector is turned off when installing and removing the UST lens.
•Do not look into straight into the projector lens when the projector is operating. The bright light may
cause permanent eye injury.
•Make sure no personnel or object is in the light path of the projector when It is running.
•Do not place the projector on an unstable surface to prevent product damage and personal injury.
•Failure to follow the control, adjustment or operation procedures may cause damage by the exposure
of laser radiation.

Identifying product versions
The UST lens kit is designed with two types of installation accessories in order to fit the different lens shift
modules (LSM) on the projectors. These instructions contain installation steps for both types. Please check
the projector’s boresight to identify the version of the lens shift module.
Note: Make sure the projector is turned off before checking the boresight.
•Type 1 Lens Shift Module (LSM 1)
•On LSM 1, the boresight plate is secured with three screws.
•Compared to LSM 2, LSM 1 has a lens cable plugged to the circuit board on the top left corner.
•Type 2 Lens Shift Module (LSM 2)
•On LSM 2, the boresight plate is secured with four screws.

Setting the projector start mode (excluding ZU860)
Set the start mode of the projector to get it ready for UST lens installation. During the setup process, the
projector reduces the image brightness and performs a lens calibration to center the lens position.
1. Remove the lens cap.
2. Install a non ultra-short throw (non-UST) lens on to the projector.
3. Turn on the projector.
4. Enable the UST Install mode though the on-screen display (OSD) menu.
a. Select Menu > Service
b. Enter the service password (which is 1590 or LEFT, DOWN, RIGHT, UP) and click OK.
c. Select UST Install > Start.

5. A lens calibration is performed.
6. To turn off the projector, press the “Exit“ key on the remote control.
7. Switch off the AC power button.
8. Remove the power cord.
Or if you do NOT have a non-UST lens for this projector, or are using a ZU860, please use
one of the following steps.
Option 1:
a. Turn the projector on
b. Send RS232 command which is ~XX361 1 or for the ZU860 use ~XX525 3
c. Projector will perform a lens calibration.
d. If command is successful, Projector will power down to standby.
Option 2:
a. Turn the projector on
b. Using buttons on the rear of the projector press in sequence EXIT, INPUT, LEFT, RIGHT (same
for all models)
c. Projector will perform a lens calibration.

Removing the non-UST boresight plate
To replace the projector with a UST lens boresight plate, complete the following steps.
1. Remove the non ultra-short throw (non-UST) lens.
2. Remove the screws securing the non-UST lens boresight plate with a Philips #2 screwdriver.
LSM 1: three screws
LSM 2: four screws
Note:
To have better visibility for the lens holder, you can stand the projector with the lens opening facing up.
3. Remove the non-UST lens boresight plate from the projector.
LSM 1: three screws LSM 2: four screws

Installing the UST lens boresight plate (LSM 1)
For type 1 lens shift module (LSM 1), you need to install a UST lens boresight plate in order to attach the
UST lens to the projector.
1. Disconnect the lens cable from the small circuit board on the lens shift module.
Note: Ensure the cable is not wrapped or pinched when replacing the lens boresight plate.
2. Insert the UST lens boresight plate in to the projector.
3. On the UST lens boresight plate, install and tighten the 3 screws with a Philips # 2 screwdriver.
4. Connect the lens cable to the boresight plate.

Installing the UST lens pogo pin adapter (LSM 2 ONLY)
For type 2 lens shift module (LSM 2), you need to install an UST lens pogo pin adapter in order to attach the
UST lens to the projector.
1. Loosen the three screws on the UST lens pogo pin adapter with a Philips #2 screwdriver.
The middle screw controls the lateral position of the circuit board on the adapter:
•Turning the screw counter-clockwise moves the circuit board towards the screw.
•Turning the screw clockwise moves the circuit board away from the screw.
To install the pogo pin adapter correctly, turn the middle screw counter-clockwise for at least 3 turns
before the installation.
2. Insert the UST lens pogo pin adapter in to the projector.
Note: Before installing the pogo pin adapter, make sure the middle screw on the adapter is turned
