By purchasing the digital radio DVR set, you have acquired a product designed to the state of the art and 

operationally reliable. Nevertheless, problems or errors may occur. Therefore, observe the following infor-

mation about troubleshooting.

Radio camera image is not displayed
•  Each radio camera (up to 4 are possible) must be logged on to the DVR. This process is also called „Pai-

ring“. Observe chapter 11 c), function „Pairing“.

  The radio camera enclosed with the DVR-set usually has already been paired by the manufacturer (ca-

mera/channel 1). If no image appears anyway simply perform pairing again.

•  Test the function by operating DVR and radio camera at a distance of no more than 2 m. If required,

perform the login („pairing“) again; see above.

•  Check if the channel for the radio camera was switched off, see chapter 11 c), function „Activation“. If

this is the case, switch on the channel again.

•  Pick the right radio camera/channel.
•  Check if the radio camera is supplied with power through the plug-in mains adapter.
•  Check if the aerial of the DVR or radio camera is screwed on correctly.
•  Observe Chapter 13.

Motion detection is not working correctly
•  Use a different sensitivity setting.
•  Align the radio camera differently.
•  The motion detection is based on the quantity of changing image parts in the monitoring area. If, e.g.,

leaves of a tree or bush are moving, this is recognised as movement and the recording is started. 

  Quickly changing brightness situations (sun/clouds) may be recognised as motion and the recording may 

be started.

SD/SDHC memory card is not recognised
•  The DVR can only be operated with SD memory cards up to 2GByte or SDHC memory cards up to 32GByte.

Use of SDXC memory cards is not possible.

•  Format the SD/SDHC memory card with the corresponding function of the DVR, see chapter 11 e), func-

tion „SD format“.
