For Blumax-devices, you find the pre adjusted configuration as an image format and for the Sanav-devices Geräte as download and installable text-files for the configuration software form Sanav. In the brackets you find the appropriated times for each configuration and need. If you configure the devices on your own, there could be the danger of commiting extra costs while the device is sending sms. For the first installation of your device, we recommend to use these installation data to be on the safe side.
