Set the receiver to the desired frequency as at
right.
r
Set the connected terminal unit to the appropriate
settings.
• Refer to the terminal unit’s instructions.

Frequency settings depend on the mode used.
FM mode:
[Setting frequency (displayed freq.)] = [Desired
[Setting frequency (displayed freq.)] = [Desired
freq.]
USB mode:
[Setting frequency (displayed freq.)] = [Desired
[Setting frequency (displayed freq.)] = [Desired
freq.] – [Center of Mark and Space freq.]
CW narrow mode:
[Setting frequency (displayed freq.)] = [Desired
[Setting frequency (displayed freq.)] = [Desired
freq.] – [Center of Mark and Space freq.] + [600 Hz]
LSB mode (for amateur RTTY):
[Setting frequency (displayed freq.)] = [Desired
[Setting frequency (displayed freq.)] = [Desired
freq.] + [Mark freq.]
The RS-R75 remote control software is available
