[. . . ] No risk of personal injury, fire or electric shock. PRECAUTIONS CAUTION!The coaxial cable between this down converter unit and your transceiver should be clamped to the antenna pole to prevent the down converter unit from weighing down the preamplifier.

The built-in protector may not function correctly when accidental transmission such as continuous transmission is applied. Confirm a satellite's operating mode in advance through documentation (magazines, etc. ) or via appropriate satellite tracking software. In the wrong mode, you cannot use the satellite even if you receive its beacon signal. s Activating the satellite mode Operating frequencies in satellite mode can be set both before and after activating the satellite mode. to transfer the frequencies, set in steps q and w, into the satellite VFO. · "SATL" indicator with either "NOR" or "REV" indicator appears. · VFO and memory mode indication are displayed in the SUB band (lower area) during satellite mode. s Tracking selection REV ] for 1 sec. to switch bePush [F-INP ENT NOR tween normal and reverse tracking. ï Normal tracking Both downlink and uplink frequencies increase or decrease in the same step simultaneously by tuning dial rotation. ï Reverse tracking The downlink frequency follows the tuning dial rotation, however, the uplink frequency changes in the reverse direction to the tuning dial rotation in the same step.

[. . . ] CONVENIENT: As the transceiver has 10 satellite memory channels, once set, desired satellite frequencies can be recalled instantly. NOTE: As the downlink (MAIN band) signal is applied to the SUB band unit receiver circuit in satellite mode, an optional FL-133 CW NARROW FILTER is necessary to operate CW-N mode. w Set the desired downlink frequency to the MAIN band and uplink frequency to the SUB band, as well as operating mode. · Push [Scan .
