  • Page 17 HC5-10 When left one phase of the mains power, that is not what it feeds the HC5-10, the transmitter reduces its RF output power to a value that doesn't exceed the 5KW. If the power of programmed regime is inferior to the value of 5KW, doesn't happen any reduction.

    For this reason, some options that are related to other kinds of devices are deactivated in the software version that is installed in the HC5-10 (see for example the P.A. menu). Note that some of the parameters that are measured and can be read may be, in some circumstances, not available.

    The hybrid coupler is factory-adjusted so that the transmitter it is included in will work satisfyingly works over the whole FM band. Cases may happen, that it is necessary to perform the RF adjustment of the HC5-10, for example if the RF interconnection cables with the amplifiers have been sustituted with other of slightly different characteristics or length, or if it is desirable to optimize the transmitter’s performances on a certain frequency.

  • Page 38: Maintenance Procedures

    10.1 Routine Maintenance The only regular maintenance needed by HC5-10, is the periodic substitution of the blowers, and the cleaning of dust filters and any dust accumulated inside the amplifier. The time between overhauling of the blowers depends upon several environmental factors, temperature, humidity, dust pollution etc.
