of the embedded cellular radio. Please refer to the Plug-In User Manual for power supply characteristics of the embedded Plug-In Module in the
Terminus T3. Plug-In User Manual can be downloaded at http://www.janus-rc.com/terminuscf.html

Note:
1) Average Supply Current specification is stated as the maximum average current the Terminus T3 terminal can draw while maintaining junction
temperatures within the internal power supply IC’s specifications. It is the applications responsibility to maintain operation within this limit to maintain
reliable operation over the life of this terminal product.
2) Values taken with GPS turned OFF. When GPS is used, expect a 20mA increase during operating states.
