Service
Solutions
• Disconnect and reconnect the power cable, and
try to turn the projector on again.
• Low battery power. Connect the projector to an
external power supply.
• Press and hold
longer than ten seconds. If this
does not work, disconnect the power cable.
• Low battery power.
• When the projector is running for a long period of
time, the surface becomes hot.
• Check that the power cable is connected correctly.
• When connecting a USB device to the projector
using the supplied USB cable, use an external
power supply to power the projector, not built-in
battery.
• The projector does not support the exFAT file
system.
• Format the USB stick in FAT format, then use it.
• We recommend checking regularly for new
firmware of your projector (see Update software,
page 14).
• In order to allow screen mirroring, your device
must support Miracast. Not all Android devices
support this function. The function name can be
also known as Screencast, Screen Sharing, WiFi
Direct, Wireless Display, etc..
• Please refer to the user manual of your Android
device to check if this function is supported and
how it can be enabled.
• The available WiFi bandwidth is insufficient for
sending the video flawlessly from the smartphone
to the projector. This can happen if one or more
WiFi networks operate in the same frequency
range nearby. Certain IoT devices (e.g. ZigBee
enabled devices) also operate in this frequency
range.
• Your smartphone is not fast enough to compress
the screen data and send it simultaneously over
WiFi.
• Your smartphone may maintain parallel
connections to your home network and the
projector. This will reduce the available bandwidth.
Disabling temporarily the connection to your
home network may help.
• For this projector it is normal to generate moderate
heat during operation.
