Furuno FS-1503 manual Displaying Station Name, Transmitting, Tuning the antenna

1.9 Displaying Station Name

User channels 0-01 to 0-65 can be registered with a name, and it or the Rx frequency can be displayed on the second line of the display. This function is available when a system setting is set to display both channel and frequency. See page 3-3 for how to register station name.

1.Press [ENT] and [CURS/2] keys together. Each time those keys are pressed together, Rx frequency or station name is displayed on the second line of the display.

2.When station name is displayed, you may press the [ENT] key to display Tx and Rx fre- quency temporarily.

RX freq Station CH No. (Example)

DUP		DUP
R	Press ENT + CURS		R
0 2 4 6 8 10 S		0 2 4	6 8 10 S
AGC			AGC
TLX			TLX

Note: If no station name is registered,

Rx frequency is soon displayed.

1.10 Transmitting

After selecting class of emission and frequency, you can transmit by pressing the PTT (press- to-talk) switch on the microphone (handset). (“T” appears when the PTT switch is pressed. Output power can be evaluated on the operation display. Do not transmit any signal other than emergency during the silence period, 00 to 03 min, and 30 to 33 min of every hour.

Tuning the antenna

Maximum transmission power is achieved only when the antenna impedance and transmitter impedance match each other. Because the antenna impedance changes with frequency a means must be provided to match (tune) the antenna impedance with the transmitter impedance. This is done with the antenna coupler. The antenna coupler automatically tunes the transmitter to a wide range of different antenna length (6 – 15 m). To initiate the automatic tuning, do the following:

1.Press the PTT switch on the microphone (handset), or the [TUNE/7] key.

2.“TUNE” appears on the display.

3.Tuning will be completed within 2 to 15 seconds for a newly selected frequency, or less than 0.5 seconds for a once tuned frequency. (A built-in memory remembers coil and capacitor settings.)

4.When the tuning process is successfully completed “OK” appears.
