• Make sure the power adapter is plugged into a
working outlet. When you connect the power adapter to
the device, the power indicator should be lit.
• Make sure you are using the power adapter included
with the device.
• Battery may not charge when operating at high
temperatures.
Sound
• Make sure the sound playback 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 no audio issues were
previously observed, the problem may happen 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
on the desired volume level. The level of the recorded
sound may not be sufficient to successfully record it.
• Make sure the proper recording software is installed.
Reinstall the software if necessary.
Miscellaneous
• Make sure the USB-device is functioning properly. If
you use an external hard drive, make sure it is connected
to the working power supply.
