  • Page 16 5.1.6 Initial start-up and setting of operation For initial start-up, follow the procedure below. Due to its function, an HC04CH-FM is always used inside a transmitter. The description given in this section therefore refers to these devices in general. When the HC04CH-FM is powered up, check that the POWER lamp lights up.
  • Page 17 HC04CH-FM ELETTRONICA Activate the exciter at minimum power and wait for it to lock onto the working frequency. Once the exciter has locked on, gradually increase its output power, checking the exciter instruments, the amplifiers and the combiner display. Increase the power of the exciter until the combiner output reaches the desired value, that is, the full power of the station at the very most.
