Solution
• Check the batteries of the remote control.
• For this projector it is normal to generate
moderate heat during operation.
• Check that the HDMI cable is plugged in correctly.
• Make sure that the laptop has been switched to
projector display.
• Turn on the Bluetooth device and make sure it is
in pairing mode.
• Position the Bluetooth device so that it is less
than 10 m (33 ft) from the projector.
• To connect Bluetooth speakers/headphones to
the projector, make sure the projector is on.
• To connect a Bluetooth playback device to
the projector, make sure the projector is off (in
standby mode).
• If another Bluetooth device is already connected
to the projector, disconnect it.
• Move the projector farther away from other
devices (microwave oven, wireless router, etc.)
that are emitting radio frequency signals.
• Check if the Bluetooth device's volume is at the
minimum.
• Check if projector's volume is at the minimum.
• Check if the playback has started.
• Try playing another video/audio file.

DMD displays from Texas Instruments typically
contain a small number of pixels that do not
function normally. Your display has been inspected
and is in compliance with the manufacturer's
specifications, meaning that any pixel defects will
not affect the operation or use of your display.
Without prejudice to generality of the foregoing, a
display with no more than 7 dead pixels meets the
factory specifications and is not considered a defect
under this warranty.
