Furuno FS-5070 manual Reducing transmitter power, Condition of the transmitting unit

2. SSB RADIOTELEPHONE

completed, TUNE: OK appears. If tuning fails, TUNE: NG appears.

2. Hold the handset close to your mouth, press the PTT switch and speak clearly.

Note: When tuning is initiated in the two control units system, the display of the idle control unit shows “OCCUPIED(ANOTHER CONTROLLER).” In this case, only the DISTRESS button is operative on the idle control unit. Further, if a control unit is in use when the other control is tuned, the display of the activated control unit shows “OCCUPIED” plus the reason why cannot use: ANOTHER CONTROLLER or NBDP to inform you that tuning is not operated.

2.3.2Reducing transmitter power

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 HIGH, MID, LOW (1) or LOW2 (shown on FS-5070) in the equipment states area and then push the ENTER knob.

2.Rotate the ENTER knob to choose a power 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. For FS-5070, when the over current is detected, output power is automatically reduced.

2.3.3Condition of the transmitting unit

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

1.Rotate the ENTER knob to choose RF, IA, IC or VC (whichever is displayed) in the equipment states area, and push the ENTER knob.
