USB data carrier is not recognised
• The screen/DVR can only be operated with USB data carriers up to a capacity of 1 TB.
• The screen/DVR can only handle the file format FAT or FAT32, but not, e.g., NTFS.
• Format the USB data carrier with the corresponding function of the screen/DVR, see chapter 11. e); all data on the
USB data carrier will be lost. Depending on USB data carrier size, formatting may take a while.
• Select the right data carrier for saving (either memory card or USB data carrier; see chapter 11. f).
• Switch off the screen/DVR and then on again.
• If a USB hard disc is connected, check if it is switched on.
• Try using a USB hard disc with a dedicated mains unit. Some 6.35 cm-/2.5"-USB hard discs (that work without a
mains unit) need too much power (especially when starting up).
Recordings cannot be saved
• Is the data carrier full? Insert a new, empty memory card or connect a new, empty USB data carrier.
• If necessary, activate automatic overwriting of the memory card or the USB data carrier; see chapter 11. d). The
oldest recordings are overwritten with the respective current recording here and will be lost.
When overwriting is deactivated, no further recordings can be saved when the data carrier is full.
• Format the memory card or the USB data carrier with the corresponding function of the screen/DVR; see chapter
11. e). All data on the memory card or the USB data carrier will be lost. Depending on USB data carrier size,
formatting may take a while.
• The screen/DVR can only handle the file format FAT or FAT32, but not, e.g., NTFS.
• If problems occur when saving on a MicroSD/MicroSDHC memory card, observe that it corresponds at least to
"Class 4" or higher; see chapter 8. a). This ensures that the speed of the memory card is sufficient to ensure con-
tinuous recording of the video data.
No audio signal from the radio camera
• The screen/DVR offers setting of the volume, but the radio cameras have no microphone.
Whistling sounds/noise
• The screen/DVR offers setting of the volume, but the radio cameras have no microphone. Therefore, no audio
signals can be recorded.
Reduce the volume to the minimum, see chapter 11. o).
Recording cannot be played back
• While the video signal is being recorded, no recording can be played back. This also applies if an existing recording
is to be played back via the Android or iOS-App.
