Reducing transmitter power | Furuno FS-1570, FS-2570 instruction

2 SSB RADIOTELEPHONE

2.1.6 Reducing transmitter power

To conserve energy and to minimize possible interference to other stations, reduce the transmission power. This should be done when using the transceiver in a harbor, near the shore or close to communication partner (other ship).

1.Rotate the [ENTER] knob to choose LOW, MID or HIGH (whichever is shown) at the top of the screen and then push the [ENTER] knob.

MODE: SSB	SIMP	LOW
		LOW

CH: 200			MID
TX: 2182.0			HIGH

	FS-1570	FS-2570
LOW	68 W	70 W

MID	100 W	125 W
HIGH	150 W	250 W

2.Rotate the [ENTER] knob to choose power among LOW, MID and HIGH as appropriate and then push the [ENTER] knob.

Note: Power amplifier temperature is monitored, and when its temperature rises above a certain temperature output power is automatically reduced.

2.1.7 Displaying IA, IC, VC or RF

While transmitting, you may display RF (PA output), IA (antenna current), IC (collector current) or VC (collector voltage), at the lower right corner of the radiotelephone screen.

1.Rotate the [ENTER] knob to choose RF, IA, IC or VC (whichever is displayed) at the bottom right corner.

2.Push the [ENTER] knob.
