This message can only arise if the Sunny WebBox is used with a GSM modem. The disturbance is not caused by the Sunny WebBox itself, but signalizes that the quality of the GSM reception is not sufficient.
The following measures can help to improve the GSM reception:
- Change the location
- Use an external antenna
- Install the SIM card (?) in a cellular phone as an experiment to check the reception quality at the location
- Select a provider with better network coverage at the location
