No/Low Sound; Noisy Fan - Dr. J HI-04 Quick Start & Troubleshooting Manual

6.4 No or low sound
If connecting with a VGA cable, use a 3.5mm headphone
line to connect device audio with the projector.
If using HDMI, USB, or other means of connection, please

contact for support.
We will send you an update to upload to the projector to
restore sound for both internal and external speakers.
6.5 Projector fan is too noisy
The projector fan should not be louder than the audio
output. However, noise from the fan is inevitable as it
keeps the projector from overheating.
Please see section 6.4 if the fan drowns out the audio ou-
tput.
