Problems with
sound recording
• It is possible that the battery is very low. In this
case, the system automatically prevents the complete
discharge to avoid loss of information and stored data.
Before you make an attempt to re-enable the device,
charge it for at least 5 minutes and disconnect the power
adapter from the wall outlet during operation.
• You may use programs that require a large
expenditure of energy. Most energy is spent on viewing
the video.
• Try to establish a better screen brightness.
• Install the latest firmware.
• The battery is discharged during operation at low
temperatures.
• Make sure the power adapter is plugged into a
working outlet. When you connect the power adapter to

Sound
• Ensure that the sound reproduction is enabled in the
basic system settings. Make sure that the volume is set to
the maximum or your desired level.
• Many of the problems with the playback of audio
are associated with the software. If the previous audio
problems were not observed, perhaps, its absence is due
to incorrect software installation or configuration of the
installed program. To resolve the problem, contact the
manufacturer of the software.
• Check for damaged files. Try to play another file in
another directory.
• Make sure that the device's microphone is directed
towards the sound source, and that the record displayed
