This manual describes the PJ20KPS-C/PJ25KPS-C, a solid-state RF amplifier designed for frequency modulation sound broadcasting, manufactured by R.V.R. Elettronica S.p.A. Being the PJ20KPS-C/PJ25KPS-C a combination of two PJ10KPS-C or PJ12K5PS-C, in this manual is described the general operation of the transmitter and of the devices present in addition, instead of with regard to the single transmitter refer to the manual of PJ10KPS-C.
Very often installing errors are discovered by dealers. If your dealer cannot help you, contact R.V.R. Elettronica and explain the problem. If it is decided to return the unit to the factory, R.V.R. Elettronica will mail you a regular authori- zation with all the necessary instructions to send back the goods.
