d) Use of Automatic Tuner
To complete the programming it is necessary to match the antennas to the
amplifier by operating “TUNE“ (read the “TUNER“ chapter of this manual).
We recommend you to select each band (with available antenna) and then
program the tuner for the sub-bands within which you will operate.
Refer to the table in section 18 of this manual to select the appropriate
sub-bands for your operating preferences.
Progress as follows:
1) Find the central frequency of the sub-band to tune in the table (refer to
section 18 of this manual) and set the transceiver to that frequency.
2) Set your transceiver to transmit a continuous tone in RTTY or CW.
3) Press the [TUNE] key. The procedure for automatic tuning will start and
then it will stop when SWR is at a minimum. Sometimes it is possible to
improve tuning by pressing the [TUNE] key again.
4) Repeat the previous steps for all bands and sub-bands you want.
5) Repeat the previous steps for the eventual other antenna of the same
band after having selected it using the [ANT] key.
Note: if the ALC link is not used, it is preferable to reduce the transceiver power
to about 50 Watts during this operation.
Note: as a default, the table is programmed for standard 50 ohm out. If, for a
band/antenna, you want to reset to default programming, proceed as
follows:
- Go to the “ANTENNA“ menu page and set this band/antenna to
“NO“, then exit from that page.
- Go to the “ANTENNA“ menu page again, assign the appropriate
antenna to this band, then exit from that page.
The programming will be reset for 50 ohm output.
The initial programming concludes after steps a), b), c).

procedures, please refer to “18. APPENDIX 1”.
