FC automatic antenna tuner – 10 (manual plus experience)
The FC-10 automatically tunes the HF transceiver and antenna frequencies using microcomputer control. This feature is especially useful, when the SWR of the antenna is not low enough for the frequencies, which are far from the resonant frequency of the antenna.

* The broadcast may begin.
Tuning
* When the SWR is less than 1.5:1 tuner data is stored in memory. Press the TUNER button – then this frequency is automatically transferred to the stored data and retrieved from memory.
Debugging takes approximately 1 to 10 seconds
* When SWR is 1.5:1 in this case, turn the RF PWR knob clockwise, tuner data is not saved. This means that you must press the START button every time, when you are working near this frequency to restart a new tuning.
Debugging takes approximately 10 to 30 seconds
* When SWR exceeds 3:1, and or, when tuning takes longer than 30 seconds, appears on the FT-840 display “Press the TUNER button on the FT-840 to call up”.
If you decide to broadcast with such a high SWR, first turn off the tuner by pressing the TUNER button and reduce the transmitted power by turning the PWR knob to the left (counterclockwise).
These steps will reduce the resistance to the end output of the transistor as low as possible, adjusting the optimal conditions for transmission.
NOTE: (broadcast with SWR 3:1 and higher may damage the tuner).
*Although the FC-10 can reduce the SWR in its alignment time intervals (reconciliation) with the output stage of the radio station, the current resonant frequency of the antenna member will not be adjusted (i.e.. the antenna does not tune). We recommend adjusting the antenna to an acceptable level and reducing the SWR to the minimum possible level before using the antenna tuner.

* When you want to use the BACK UP switch, always make sure the FC-10 is turned off first.
* Do not place any objects in front of the FC-10 fan grilles, separately in the front of the device.
* When connecting a CNTL cable, always turn off the FC-10 first. If the CNTL cable is switched while the device is switched on, (lights up on the FT-840 display “Press the TUNER button on the FT-840 to call up”) a warning signal sounds and goes out “Press the TUNER button on the FT-840 to call up”. When reconnecting the cable in such a situation, always turn off the power of the FT-840 first.
* Message “Press the TUNER button on the FT-840 to call up” appears only on the FT-840 display, when FC-10 is connected, and does not appear when the FC-800 is connected.

Both connectors are the same 8-pin ( if you swap them, “POWER LED” lights up and the tuner stops working, preventing any possible damage).
FAULTS
* The TUNER and START buttons do not correspond ! Turn off the power, check the cables and turn on the power again
* Tuning stops soon after the START button is turned on ! When the START button is pressed, tuning starts in the frequency band in the FC-10 memory. When SWR antenna is 1,5 or lower, will appear “Press the TUNER button on the FT-840 to call up” on the FT-840 display and tuning will end soon

2, Minor experience with FC-10, Minor experience with FC-10, but he didn't want to stop. And yet, that the antenna had SWR 1,7. It might happen, that the relay contacts will stick together. This randomly resolved the issue before sending it for repair, that after being transported by car and after moving to another place, the tuner started working again and still works today. That would be a calibrated punch?
3, If it happens to you, if you accidentally connect the coaxial cables on the tuner in the opposite way and key them, HI SWR will light up , so stop broadcasting and check the cables quickly and pray, to make it work as it should. It can happen, But not always that device can survive in a healthy way.
