2.13. Putting into operation
Before putting the MR36 router into operation it is necessary to connect all components
needed for the operation of your applications and the SIM card must be inserted (the modem is
off).
The modem is put into operation by connection of the power supply to the modem.
In the default setting the modem starts to login automatically to the preset APN. The behavior
of the modem can be modified by means of the web interface which is described
in the following chapter.
