 # Settings and options
 
-During normal operation of the photometer, we can select the gear (also press the joystick) and we will enter a menu with several options (information about the device, current Wi-Fi information, reboot and Reset device configuration, including the wifi setup). Among them, you will see "Data mode setup" and it will show three enable/disable possibilities:
+Remember that, for your FreeDSM to take part in the data collection campaign, you must create a profile and register the instrument on our website: http://dsm.citic.udc.es/
+
+During the photometer’s normal operation, you can access the Settings menu, represented by a gear icon, by pressing the physical joystick next to the small LCD screen. Several options are available there, but the one we are interested in is “Data mode setup”, where you will find three additional settings that can be enabled or disabled. Two of them are relevant here:

-Here you can disable the sending of data to the Gaia4Sustainability project platform (we recommend do not disable it, at  https://dsm.citic.udc.es you can register and view your data).
-
-Other option is to enable/disable the storage of the data in the device's internal flash (datalog.json file; very limited space, around 16h of data); It is possible to download these JSON files through the photometer's web interface with any web browser, using the IP that the device has assigned in our network. To do this, select "Console" or "Tools" -> "Manage File system" and click on the file to start the download.
+a) “Save local” is enabled by default and allows the FreeDSM to automatically send measurements to the platform.
 
-The third option is to enable the "eclipse mode"; the instrument will configure the sensor to perform correctly during the elipse, and the previous hours, on August 12, 2026. In this mode, the instrument will show an eye and "eclipse" on the main screen.
+b) If you enable “eclipse mode”, the sensor will adjust its sensitivity so that it works correctly during the eclipse and in the minutes leading up to it on August 12. When this mode is enabled, an eye icon and the word “eclipse” will always appear at the top of the LCD screen. Remember to update the location of your FreeDSM at http://dsm.citic.udc.es/ so that it matches the place where you will be using it to monitor the eclipse.

+c) Ideally, your FreeDSM should be connected to a Wi-Fi network with Internet access. Remember that you can always create a Wi-Fi hotspot using your mobile phone if no other option is available.
+If connecting it to the Internet is not possible, you can enable the “Save local” option so that the captured data is stored on the photometer itself in JSON format. This data can be downloaded through the web interface. Select “Console” or “Tools” → “Manage File System”, and then click on the “datalog.json” file to download it (very limited space, around 16h of data). If you used this option for the eclipse, please send this file by email to info@gaia4sustainability.eu, including the name of the photometer and its geolocation.
+
+Remember that, without an Internet connection, the instrument will not be able to synchronize the date and time automatically. During the boot, it will therefore ask you to configure them manually (year/month/day/hour/minute).

 # How the sensors work
 
 The photometer takes 6 light measurements at the end of each minute, sending the data. Additionally, it incorporates temperature and humidity information, as well as the raw measurements used for the calculation of mpsas and their calibrated value (calibrated mpsas are displayed on the LCD screen). The device has a built-in generic average adjustment, with which we have obtained an error of about 0.11 mpsas (on moonless nights) in relation to the measurements of a Tess-W. It is possible to perform individual calibrations with parallel FreeDSM / Tess-W measurements, although it is outside the scope of this document. In such cases, the error is reduced to 0.5 mpsas.
