Switches
DIP-switch
The M2M CONTROL CX660 device contains two dip-switches. The dip switches are located on the
front side of the device for easy user access (see graphical overview).
System switch (RST)
The M2M CONTROL CX660 device contains a combined reset/diagnostic switch. This switch is
accessible from the front of the unit (see graphical overview). It is necessary to use a small thin
object with a diameter of approx. 2 mm, for example, a straightened-out paper clip for this
purpose.
By activating the switch shortly, the device will do a complete reset as if the power was removed
and reapplied.
If the reset switch is held down for approx. 3 seconds

the device will instead enter recovery mode
2
where the application will not be started. In recovery mode, the system will automatically turn on
any communication channel and establish a connection to the M2M Control GPRS Gateway or
M2M Communication Hub (if configured).
Pressing reset will also activate the device when in power-down mode. If external power is
removed and the backup battery is disabled, the reset switch can still be used to boot into recovery
mode, as long as there is enough power left on the battery.
