Projector Setup

Charging the Battery

Switch the Power Switch to the ON position, then press the Power button to turn the projector ON or OFF. Battery life is approximately 3 hours when at 50% Brightness/volume level. This unit has the Main Power Switch, which gives the unit power and puts the unit on standby. When powered ON and in standby mode, the battery will last approximately 5 hours.

Image Adjustment

Keystone Adjustment

For Keystone Correction, press buttons on the remote.
You can also adjust Keystone Correction by pressing the Menu button on the remote, going to the Options Menu, and selecting Keystone Correction. Use the Up and Down Arrow buttons to manually adjust the Keystone Correction.
Removing the Lens Cap
Please remember to remove the lens cap before attempting to view media.

Putting Lens Cap On
1. When putting the lens cap back on, please make sure that you retract the lens back into the projector to avoid damaging the lens. You can do this by:
1. Orient the projector with the lens facing you, as shown below. 2. Scroll the focus ring all the way to the left. Once the lens is fully retracted back inside, you may then place the lens cover back on.

Projector Placement
For best results, place the projector in a dark room or another dimly lit area. The projector will display screen size from 30 to 150. Adjust the projector angle and distance to best suit your needs. Use the unit with a dedicated projector screen for the best picture resolution. If placing the projector behind the viewing screen (unit in front of/projecting toward viewers), a special screen will be required. Projector screens are not included. If you are not using the unit with a screen, a smooth, white or lightly colored surface will provide the best results.
Angle Adjustment

Viewing Options
The projector can be used to project onto a wall or screen. It can be mounted from a ceiling or placed on a table. Be sure to aim the remote at the sensor on the front or rear of the projector. See page 6 for sensor locations on the projector. When projecting from the rear position, a special screen will be needed (not included) to display the image.

External Audio

The PJ770 has built-in full-range speakers. However, you can also connect external speakers for more sound options.
Bluetooth – Pairing to Wireless Speakers or a Sound Bar
NOTE: Bluetooth is OFF by default when the projector first powers ON. Bluetooth can be turned ON or OFF from the OPTIONS Menu (See Page 19).

1. Enable Bluetooth on the external speakers, or soundbar (Bluetooth receiver) to which you wish to connect.
2. Power on the projector and make sure the projector’s Bluetooth is ON (see the note above). The projector will begin searching for nearby Bluetooth devices to connect to.
3. Using the projector’s Arrows/OK buttons, select the Bluetooth speaker you want to connect to from the Bluetooth menu. Note: To eliminate confusion, disable Bluetooth on all receivers to which you do not wish to connect.
4. When successfully paired, the Bluetooth receiver should indicate it is connected, usually with a chime or tone. Check the user manual on your Bluetooth receiver for more information.
5. When successfully connected, the projector will display the Bluetooth receiver’s (your speaker or soundbar) name on the top right portion of the Main Menu screen, and sound played from the projector will be heard through the Bluetooth receiver.

After the initial pairing, the projector and the Bluetooth speakers will stay paired unless unpaired manually by the user, or erased due to a reset of either device. If this occurs or you find either unit is unable to connect, repeat the above steps.
Headphone Jack/Audio Out
Requires a 3.5mm to RCA audio/video cable (included). Note: Speakers must have their own power supply.

1. Using a 3.5mm to RCA stereo cable (included), connect the external powered speakers to the Headphone Jack on the projector. Note: The yellow video plug will not be needed in this setup and will not need to be connected.
