The turning off of the device can be done in two ways:

• via AT command (see GE864-QUAD / PY Software User Guide)

• by tying low pin ON#

Either ways, when the device issues a detach request to the network informing that the device

will not be reachable any more.

To turn OFF the GE864-QUAD / PY the pad ON# must be tied low for at least 2 seconds and then

released.

The same circuitry and timing for the power on shall be used.

The device shuts down after the release of the ON# pad.
