The setup menu

The setup menu allows local access to almost all settings of the user and device configuration. All changes in the setup menu are done and stored locally on the device but can be easily synced back into the configuration file using the Green-GO Control software. These settings are also persistent on the device unless overwritten.

Si4WR Setup Menu

The setup menu can be accessed by pressing Button 1+Button 2 together.

Si4WR Setup Menu

Once inside the setup menu, Button 3 and Button 4 can be used to navigate up or down.

Button 1 confirms a selection or enters a submenu.

Button 2 can be used to either cancel a selection or go one menu level higher.

Access to the setup menu can be restricted by configuring the security options of a configuration file or user with the help of the Green-GO Control software. The user may be asked to enter the Tech Pincode before access is given in restrictive security configurations.

Tip: More information on security options can be found here.
