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

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 Switching input

• Many notebooks do not turn on their external video ports when connected to a projector. 
Usually a key combo 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 notebook. 
Press FN and the labeled function key simultaneously. Refer to your notebooks 
documentation to find your notebooks key combination.

Connecting video source devices
You need only connect the projector to a video source device using just one of the 
connecting methods, however each provides a different level of video quality. The method 
you choose will most likely depend 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 on page 8). They are commercially available from electronics stores.
Connecting audio
The projector has one built-in mono speaker which are designed to provide basic audio 
functionality accompanying data presentations for business purposes only. They are not 
designed for, nor intended for stereo audio reproduction use as might be expected in 
home theater or home cinema applications. Any stereo audio input (if provided), is mixed 
into a common mono audio output through the projector speaker.
The built-in speaker will be muted when the AUDIO OUT jack is connected.
• The projector is only capable of playing mixed mono audio, even if a stereo audio input is 
connected. See Connecting audio on page 27 for details.
• If the selected video image is not displayed after the projector is turned on and the correct 
video source has been selected, check that the video source device is turned on and 
operating correctly. Also check that the signal cables have been connected correctly.

Playing sound through the projector
You can make use of the projector (mixed mono) speaker in your presentations, and also 
connect separate amplified speakers to the AUDIO OUT socket of the projector.
If you have a separate sound system, you will most likely want to connect the audio output 
of your Video source device to that sound system, instead of to the mono audio projector.
Once connected, the audio can be controlled by the projector On-Screen Display (OSD) 
menus.
The table below describes the connection methods for different devices, and where the 
sound is from.

Audio output port AUDIO OUT AUDIO OUT AUDIO OUT
The selected input signal determines which sound will be played by the projector speaker, and 
which sound will be output from the projector when AUDIO OUT is connected. If you select the 
COMPUTER/PC signal, the projector can play the sound received from AUDIO IN mini jack. If you 
select the COMPONENT/VIDEO signal, the projector can play the sound received from AUDIO 
(L/R).

a wall socket. Turn on the wall socket switch 
(where fitted). Check that the POWER

up. The projector does not respond to further commands whiles it is warm up.
(If necessary) Rotate the focus ring to adjust the image clearness.
To turn off the ring tone, see Power On/Off Ring Tone on page 59 for details.
If the projector is still hot from previous activity, it will run the cooling fan for approximately 90 
seconds before energizing the lamp.
