ETLUW4G03 TV TRANSMITTER • ETLUW4G03 TV Transmitter incorporates three ETL0W474G R.F. Amplifiers, one (two as option) Exciter, one Transmitter Supervisor & Controller, one input power divider, one output R.F. power combiner, 50 Ohm balancing loads for the combiner and one band-pass filter (option) for the attenuation of harmonics and out of band products.
CAUTION: CAUTION: CAUTION: The ETLUW4G03 transmitter unit is shipped disassembled in a series of main blocks. To assemble and install the Transmitter unit follow the steps below. For R.F./electrical connections also refer to “MAINFRAME AND WIRING DIAGRAM” provided with For R.F./electrical connections also refer to “MAINFRAME AND WIRING DIAGRAM” provided with For R.F./electrical connections also refer to “MAINFRAME AND WIRING DIAGRAM”...
First time operation of ETLUW4G03 First time operation of ETLUW4G03 ETLUW4G03 is shipped with all the main switches set in the correct configuration. So when the Transmitter is connected to mains network it will be turned off. Prior to switch on the transmitter ensure that all R.F. connections have been carried out properly.

Due to the reliability of the basic ETL0W474G module, partial failures in one RF Amplifier are very rare and total failures extremely unlikely. Replacement of an ETL0W474G amplifier module can be done without turn off the ETLUW4G03 transmitter unit. During this operation the transmitter unit will work at a lower R.F. output power.
