Connecting an MHL source device
This projector supports MHL devices (MHL-enabled) through the use of HDMI input jack. 
You can connect your MHL-enabled mobile device to the projector with an MHL cable to 
play high-definition video with fluidity.
MHL (Mobile High-definition Link) supports uncompressed video and audio transmission 
between compatible devices like mobiles phones, tablets and other portable consumer 
electronics devices and transmits signal over a single cable. It provides pure digital viewing 
and listening experience.
Examine your mobile device to determine if it is MHL-enabled:
• If so, you can continue with this procedure.
• If not, you will need to reassess which method you can use to connect to the device.
To connect the projector to an MHL source device:
1. Take an MHL cable and connect the MHL end to the MHL output port of the MHL 
source device.
2. Connect the HDMI end of the MHL cable to the HDMI 1/MHL input port on the 
projector.
Not all mobile devices are MHL-enabled. Consult with your mobile device dealer to verify MHL 
capabilities.

Connecting a component video source device
Examine your video source device to determine if it has a set of unused component video 
output sockets available:

RCA type connectors to the component video output sockets of the video source 
device. Match the color of the plugs to the color of the sockets; green to green, blue 
to blue, and red to red.
2. Connect the other end to the PC socket on the projector.
3. If you wish to make use of the projector’s built-in speakers, take a suitable audio cable 
and connect one end of the cable to the audio output sockets of the video source 
device, and the other end to the audio input socket on the projector.
• When audio output jack is connected with the earphone or external speaker, the sound will 
not come out from the projector’s built-in speakers.
• No sound will come out from the projector’s built-in speakers or audio output jack if video 
signals are not input. Besides, the sound cannot be adjusted either.
