  • Page 12: User Channels

    User channels You can recall user channels through the keyboard by channel numbers. Once a channel is selected with the keyboard, the channel can be changed with the [FREQ/CH] control. For how to write user channels, see Chapter 3. 199 user channels ( 0-01 to 0-99 and 1-00 to 1- 99) can be programmed in addition to ITU channels.
  • Page 13 ITU telephony channels (SSB) To recall ITU SSB channel 412, for example, select J3E with the [MODE/1] key. Press [CH], [4], [1], [2], [ENT], and a combination of Tx frequency of 4098 kHz and Rx frequency of 4390 kHz is selected. To select only Rx or Tx frequency, hit [RX] or [TX] first.

  • Page 14 ITU TELEX channels To select the ITU TELEX channel 4012, for example, first select TLX with the [MODE/1] key. This radiotelephone is furnished with J2B class of emission. The J2B is compatible with F1B which may be used on other parties. You do not have to worry about F1B or J2B; you can just select TELEX mode for narrow-band direct-printing.

  • Page 15: Displaying Station Name

    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.

    4. Indicate the end of message by saying “Over.” 5. When you receive no answer to a distress message, repeat at intervals over again the radio- telephone alarm signal, the distress call and the distress message. Distress frequencies All distress frequencies including 2182 kHz are shown below:...

  • Page 18: Receiving

    1.12 Receiving You can select a receiving frequency by one of the following methods: - Direct frequency entry, or - Channel number entry Adjusting RF gain In normal use the [RF GAIN] control should be set for maximum. If the audio on the received channel is unclear or interfered with other signals, adjust (usually reduce) the control to im- prove clarity.

    Receiving AM broadcasting stations 1. Press the [MODE/1] key repeatedly to select H3E. 2. To tune in a 15,260 kHz shortwave station, for instance, press as below: [RX], [1], [5], [2], [6], [0], [0], [ENT]. Be sure to enter the last zero. Squelch control Squelch is used to mute the receiver audio output when the receiver input is less than a preset value or dominant noise is higher than a preset (1000 Hz) frequency.

  • Page 20: Frequency Scan

    1.13 Frequency Scan Channel scan Scan is the function where the receiver watches 10/group user or ITU channels in succession at predetermined intervals. The scan-stop signal level and scan-stop time can be changed on sys- tem codes 9951 and 9952, respectively. AGC is automatically turned on when scanning is acti- vated.
  • Page 21 ITU channels To select the scan group (band or channel, including user channels), shift the cursor to either the position of the band or channel number by pressing the [CURS/2] key. (Band scan is useful to watch frequencies on the same channel in different bands.) 2.

    2.1 Telex Communication Telex communication is performed with a Narrow-band direct-printing (NBDP) Terminal con- nected with an SSB transceiver. The recommended terminal for the FS-1503 is the FURUNO DP-5/DP-6. Other makes can also be connected with the FS-1503, provided they comply with the interfacing requirements.

  • Page 25: Remote Station Rb-500

    The Remote Station RB-500 usually has higher priority than the FS-1503. This means that opera- tion of the FS-1503 is disabled when the handset of the RB-500 is picked up. The indication “REM” appears on the FS-1503 display when the remote station is in operation and the PTT switch on the microphone of the FS-1503 is inoperative.
