							12 Overview  
Installing/replacing the remote control batteries
1. Press and slide off the battery cover, as illustrated. 
2. Remove the old batteries (if applicable) and install two AAA batteries within. Make sure that the 
positive and negative ends are positioned correctly, as illustrated.
3. Slide the battery cover in until it clicks into place.
•  Avoid leaving the remote control and batteries in an excessive heat or humid environment like the 
kitchen, bathroom, sauna, sunroom or in a closed car.
•  Replace only with the same or equivalent type recommended by the battery manufacturer.
•  Dispose of the used batteries according to the manufacturers instructions and local environment 
regulations for your region.
•  Never throw the batteries into a fire. There may be danger of an explosion.
•  If the batteries are dead or if you will not be using the remote control for an extended period of time, 
remove the batteries to avoid damage to the remote control from possible battery leakage.
Remote control effective range
The remote control must be held at an angle within 30 degrees perpendicular to the projectors IR 
remote control sensor(s) to function correctly. The distance between the remote control and the 
sensor(s) should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote control and the IR sensor(s) on the projector.

							14 Installation  
Obtaining a preferred projected image size
The projected image size is determined by the distance from the projector lens to the screen, the zoom 
setting, and the video format.
HT1075 is equipped with movable lens. See ‘Shifting the projection lens vertically (HT1075 only) for details. 
Projection dimensions
Use the illustration and tables below to help you determine the projection distance.
HT1075
HT1085ST
All measurements are approximate and may vary from the actual sizes. If you want a permanent installation 
of the projector, we recommend that you use the actual projector to physically test the projection size, 
distance, and the projectors optical characteristics prior to the installation. This helps you determine the 
exact mounting position which best suits your installation.

  Installation
Shifting the projection lens vertically (HT1075 only)
The vertical lens shift control provides flexibility for installing your projector. It allows the projector to be 
positioned slightly above or below the top level of the projected images. 
The lens shift (offset) is expressed as a percentage of the projected image height. It is measured as an 
offset from the projected images vertical center. Use the lever to shift the projection lens upwards or 
downwards within the allowable range depending on your desired image position. 
To use the lens shift lever:
1. Release the lever by turning it counterclockwise.
2. Move the lever to adjust the projected image position.
3. Lock the lever by turning it clockwise.
•  When the screen position is fixed
•  When the projector position is fixed
•  Do not over-tighten the lever.
•  Lens shift adjustment does not result in a degraded picture quality. In the unlikely event that the image 
distortion is produced, see Adjusting the projected image for details.

  Connection
Connecting with video equipment
You need only connect the projector to a video source device using just one of the connecting methods. 
Each video source provides different picture quality. The method you choose most likely depends upon 
the availability of matching terminals on both the projector and the video source device as described 
below:
In the connection illustrations shown below, some cables may not be included with the projector (see 
Shipping contents). They are commercially available from electronics stores.
Connecting HDMI devices
HDMI (High-Definition Multimedia Interface) supports uncompressed video data transmission between 
compatible devices like DTV tuners, DVD players, Blu-ray players and displays over a single cable. You 
should use an HDMI cable when making a connection between the projector and HDMI devices.

The projector can project the content directly from a MHL compatible smart device. Using an HDMI to 
Micro USB cable or an HDMI to Micro USB adaptor, you can connect your smart devices to the 
projector and then enjoy your content on the big screen.
Some smart devices may not be compatible to the cable that you use. Please consult the manufacturer of 
your smart device for detailed information.
Using an HDMI to Micro USB cable
1. Connect one end of the HDMI to Micro USB cable to the HDMI input connector on the projector.
2. Connect the other end of the HDMI to Micro USB cable to the Micro USB output socket on your 
smart device.
3. Switch to the HDMI/MHL input source. To switch input signal, see Selecting an input source for 
details.
Using an HDMI to Micro USB adaptor and an HDMI cable
1. Connect one end of the HDMI cable to the HDMI input connector on the projector.
2. Connect the other end of the HDMI cable to the HDMI input socket on the adaptor.
3. Connect the other end of the adaptor to the Micro USB output socket on your smart device.
4. Switch to the HDMI/MHL input source. To switch input signal, see Selecting an input source for

Connecting a computer
Connect the projector to a computer with a VGA cable. 
Many laptops do not turn on their external video ports when connected to a projector. Usually a key 
combination like Fn + F3 or CRT/LCD key turns the external display on/off. Locate a function key labeled 
CRT/LCD or a function key with a monitor symbol on the laptop. Press Fn and the labeled function key 
simultaneously. Refer to your laptop
s documentation to discover your laptops key combination.
