CHAPTER 3: INSTALLATION 

 

Upon opening the shipping carton, the following items should be present and undamaged: 

 

• 

CS-540 FM Repeater System 

• 

This CS-540 Owner’s Manual 

• 

Detachable AC-line cord 

• 

One strip of four rubber feet 

 

The CS-540 is capable of producing HIGH-powered RF signals that require proper termination into 
a suitable load.  It is highly recommended the CS-540 be installed by a qualified technician with 

experience installing FM repeaters and controller equipment.  

 

Installation

 

 

The CS-540 provides 4 mounting holes on the front panel for installation into a 19” rack and 4 rubber feet for 

placement in a desktop configuration.   If installing the CS-540 in a 19” rack, use 4 rack screws (not supplied) 
to securely fasten the CS-540’s front panel flush with the rack’s rails.   If placed in a desktop configuration, it 

is recommended the rubber feet be placed close to the four corners of the bottom of the chassis. 

 
Optional accessories include a base station microphone, internal duplexer, and the PGM-540 programmer.  

Please check with your dealer for more information about these optional accessories. 

 

The CS-540 is shipped with or without an internal duplexer.  If the unit is not equipped with an internal 
duplexer, there will be an N-type female connector for RX and another for TX located on the rear of the unit.  

If the unit is shipped with an internal duplexer, there will be one N-type female connector at the TX/Duplexer 

Out port.

 

 

The internal power supply of the CS-540 is factory pre-set for 120V AC 60HZ operation to deliver 13.8 Volts.    
To convert the internal power supply to 240V AC, see Appendix E.  If the CS-540 did not come with a duplexer 

installed, connect the received signal to the RX antenna port and connect the TX antenna port’s output to 

where the powered signal is to be transmitted.  If the CS-540 came installed with a duplexer, attach the 

antenna cable to the duplexer out port on the rear of the unit.   

 

Power Up 

 

To power the unit, simply plug the detachable AC-line cord into the receptacle located on the back of the unit 

and then plug it into an AC line source.  Pressing the lighted power switch to the up position turns on the CS-
540. The power switch will illuminate indicating the unit is on.  The CS-540 will cycle through a power-up 

sequence illuminating the LCD and the LED’s.  The model name will be displayed for approximately two 

seconds followed by the version of firmware.  If the CS-540 was ordered without being custom programmed, 

the default personality will be loaded and HIGHPWR will be displayed for approximately 2 seconds and then 
dashed lines.  If the unit was ordered custom programmed, the name given to the first channel will be 

displayed instead of HIGHPWR.  If the CS-540 was ordered without being custom-programmed, you will have 

to purchase the PGM-540 repeater programmer.  Please reference the PGM-540 User’s Manual for learning 
how to program your CS-540.  Once programmed, the CS-540 will be reset and cycle through its power-up 

sequence and default to repeater mode. Note: HIGHPWR is the name of the channel programmed.  This 

channel is configured at the factory to transmit 40 watts.  Keep this in mind prior to attaching the repeater to 
a service monitor.  Depending on your test equipment setup, you may need to reduce the output power or 

pad the TX output so as not to damage your test equipment.
