and electrical interface between application and TME-3 is the M2M system connector.
The application can be powered through M2M system or the application can deliver
power to TME-3.

User Control mode
In the user control mode the Nokia 30 GSM Connectivity Terminal is controlled by a
mobile phone. Text message templates that are sent from the mobile to the Nokia 30
instruct the terminal, which in turn controls a device or machine attached to it through
the M2M System connector.
An example of a device attached to the Nokia 30 for wireless control would be a refrig-
erator. You might want to check the temperature of the refrigerator when out of town.
The temperature of the refrigerator could be altered with the mobile as well.
You could also turn off the lights of the apartment that you had accidentally left on by
sending a text message template.
There are three levels of access control for the User control mode.
Firstly, a message identifier entered when the terminal is used for the first time with the
Nokia 30 Configurator is only known by the person who entered it. This identifier begins
every text message template aimed to control the Nokia 30 and the application attached
to it.
