The SN400 915 MHz. antenna is PCB mounted and located internally to the enclosure. Note that it is possible to connect an external antenna to the SN400 device. This is supported only as an option, and should not be necessary in a typical application. - Page 8 Batteries are not supplied with the sensor node, and should be inserted by the customer at the time of SN400 installation. If the sensor node device is not to be used for a long period of time, the batteries should be removed to prevent their depletion.

Page 11: Physical Dimensions
All dimensions are shown in millimeters. 7 Installation To facilitate mounting, the SN400 is provided with two rear facing magnets for easy attachment to a ferrous metal, steel surface. Alternatively, a fastener screw, or double- sided adhesive foam tape can be used on the top flange for mounting to a wall or other flat surface. - Page 12 Ideally, the external ports should point downward to prevent ingress of spills and liquids. The image below shows the SN400 installed on the outside of a refrigerator using integrated magnets. An external wired sensor is used to sense refrigerator temperature.
