HF multi-mode transceiver KN920 operation manual (MCU v02.02)
Trimming function using the receiver
KN920 with acceptable frequency tuning function, can be adapted to receive and transmit
frequency QSO objects inconsistencies or some other conditions. To use the receiver tuning
function, you need to follow the following steps:
Repeatedly press the DIS button to adjust the second line of the LCD display characters shown
below：
Now press the F3 key will be received in the use of fine-tuning and fine-tuning

seen,
When the RIT, it means receiving trimming function is not used;
When the display similar to the following characters, that the use of fine-
tuning of the receiver.
Shown above, indicates the current receiving frequency than the VFO frequency
(LCD first line shows the frequency) high 120Hz, receiving and tuning frequency
shown in the display is corresponding to the VFO frequency, i.e. see the
numbers on the LCD of the last a bit of 10Hz.
Contents shown above represent the following meanings:
Current
VFO
frequency
is
higher
than
the
reception
frequency,
another
possibility in the display is the symbol "-", which represents the current VFO
frequency is lower than the reception frequency.
12 999 numbers or other small, representing VFO receive frequency and the
frequency difference value, the unit is 10Hz. Ie receiving trimming can be
adjusted between the ± 9.99kHz.
<Means now turn the main tuning frequency knob to change the frequency of
acceptance, rather than changing the VFO frequency.
If you need to change the VFO frequency, you can press the F4 key to switch,
