Check and report a fault

Updated on 01.11.2026

When the C.A.P. system has a fault, first check yourself whether you can solve the problem. If it persists, report it to Cyreen Support. If a service call on site is needed, costs and conditions are as set out in your contract.

Choose what you see. Each item tells you what you can do yourself.

The screen is black

Possible cause: The power supply is interrupted.

What you do: Switch the screen on. The on/off switch is at the back of the screen, at the top on the back of the speaker. If it stays black, report the fault. Read more

Report the fault
The picture is frozen

What you do: Switch the screen off and on again once. If the picture is still frozen, report the fault. Read more

Report the fault
Advertisement not played with sound

What you do: Advertising in the loop always plays without sound. Sound comes with contact-based advertising, which starts when an RFID-tagged trolley or basket passes the screen. Check that the volume knob on the back of the screen is at the 9 o’clock position. If it is not, turn it to 9 o’clock. Read more

Report the fault
The sound is too loud or too quiet

What you do: Check that the volume knob on the back of the screen is at the 9 o’clock position. If it is not at 9 o’clock, turn it to 9 o’clock. If it is at 9 o’clock, do not adjust it: if the sound is still too loud or too quiet, report it. Cyreen then takes over. Read more

Report the fault
Advertising does not start when a trolley or basket passes

Possible cause: The area reader does not detect the trolley or basket, for example because metal objects block the area in front of it.

What you do: Clear the area in front of the area reader, especially of metal objects. Then test with an RFID-tagged trolley or basket. Read more

Report the fault
A device is damaged

What you do: Do not repair, move or remove the device yourself. Take a photo that shows the device number and report the damage. Read more

Report the fault
Another fault on the C.A.P. system

What you do: Describe as precisely as possible what you see, on which device and since when.
