Programming Over-the-Air 
Over the air programming of the main processor allows the user to program the device 
without having any local access to it.  Only devices with software version 2.20 or higher are 
able to be programmed in this fashion.   
Over the air programming uses an SMS command to initiate an Over-the-Air code download, 
so  a  GPRS  connection  is  required.    In  areas  with  very  weak  or  no  GPRS,  this  method  of 
loading code will fail.  Also, before proceeding with an over the air programming, ensure the 
device will remain on for the entire programming sequence. 
For instructions on performing an over the air code upgrade, please consult the IMB O&M 
manual.
