2.Enter frequency by one of the methods below.

Entering frequency with the numeric keys:

Use the numeric keys to enter frequency and then push the ENTER knob. For example, to enter 2161 kHz, key in 2, 1, 6, 1, 0. (Keying in 2-1-6-1 will set 216.1 kHz.) Be sure to include zero for 100 Hz place.

Choosing frequency with the ENTER knob (for RX only):

3.Use the FILE/CURSOR key to choose digit to change.

4.Rotate the ENTER knob to set digit.

5.Push the ENTER knob.

Note: When Tx and Rx frequencies are different, enter Tx and Rx in that order: Tx: Tx/Rx frequencies

Rx: Rx frequency only

2.3Transmitting

After selecting class of emission and frequency, you can transmit by pressing the PTT switch. Tx is shown on the display.

2.3.1Transmitting procedure

Maximum transmission power is achieved only when the antenna impedance and transmitter impedance match each other. Because the antenna impedance changes with frequency, antenna impedance matching with the transmitter impedance is done with the antenna coupler. The antenna coupler automatically tunes the transmitter to a wide range of different antenna lengths, from 7 to 18 (FS-1570/2570) or 10 to 18 (FS-5070) meters.

To initiate the automatic tuning, do the following:

1.Press the PTT switch on the handset or the LOG/TUNE key more than one second on the control unit. Tuning is automatically adjusted at first transmission after frequency is changed. “TUNING” appears when the LOG/TUNE key is pressed more than one second; “Tx” pops out when the PTT switch is pressed.

Tuning will be completed within 2 to 5 seconds for a newly selected frequency, or less than 0.5 seconds for a once-tuned frequency. When the tuning process is successfully
