Installation and Programming 

 

71-506-10D can be installed to operate Fixed Station in any mode of operation.  The antenna(s) 
used for this transmitter must be fixed-mounted on outdoor permanent structures.  RF exposure is 
addressed at the time of licensing, as required by the responsible FCC Bureau(s), including 
antenna co-location requirements of §1.1307(b)(3). 
 
The radio may also be used for mobile and transportable applications. 
 
The 71-506-10D must be programmed before it will operate correctly. This is best done by the 
equipment supplier or a competent radio engineer. They will require the correct programming kit 
and a computer.  Complete programming instructions are provided with the kit.  If a duplexer is 
used, please observe the maximum frequency range permitted by the duplexer notches. 
 
It is important that the 71-506-10D be correctly installed at its working location. It is recommended 
that this be done by a competent radio engineer.  
 
As a minimum, it is necessary to: 
 

• 

Securely attach the mounting plate to the desired location. 

• 

Connect the DC Input power lead to a suitable 13.8 Volt Regulated DC Power supply that 
has sufficient capacity. (Ensure that the DC Polarity is correct, otherwise the fuse will 
blow). 

• 

Connect the antenna feed line(s).  (Check that the VSWR of the antenna is acceptable). 

• 

Connect the Control System to the 25 position sub D connector.
