 MPE COMPLIANCE
            MPE compliance distance: 1.28 meters (4.2 feet)

            Users and other nearby individuals maintain 1.28 meters (4.2 feet)
            or more from a boat-mounted antenna during transmission.


      Compliance with the FCC's MPE limits in 47 CFR Section 1.1310, Table 1(b).

* Maximum permissible exposure (MPE): The rms and peak electric and magnetic field
  strength, their squares, or the plane-wave equivalent power densities associated with
  these fields to which a person may be exposed without harmful effect and with an
  acceptable safety factor.


Operation


1.   Controls




                       Figure 1: Controls




(1) POWER/VOL Control:Turns the radio on and off, and adjusts volume of the speaker.


@ SQUELCH Control:      Adjusts the squelch. Rotate the control counter—clockwise until noise
                        is heard, then rotate it clockwise slowly until noise just fades out.


@) 16/9 Key:            Immediately recalls CH16 from any channel location. Pressing this key
                        for more than 1 sec recalls CHO9.


@ U/I/C(USA, International, Canadian)Key :   Holding down this key for more than 1
                        sec changes the channel modes from USA, International to
                        Canadian.    "USA" or "INT" will appear on the LCD display for
                        each mode, but no indicator will be displayed for Canadian
                        channel mode.


(8) WX Key:             This key has double functions. When pressed once, it selects the weather
                        channels receiving mode. "WX" will appear. While the radio is in this mode, the
                        transmitter is always disabled.
                        When pressed for more than 2 sec, it switches the LCD backlight on and off.


   MEMO/SCAN Key:       Controls the memory function. All receiving channels except weather channels
                        can be stored in this memory.
                        Channel Memory:
                            First select the channel to be memorized, then hold the MEM/SCAN key
                            down until a beep sounds (approx. 2 seconds). "MEMO" and the channel
                            number will appear on the LCD.
                           To store more channels, repeat the same procedure.
                        Memory Scan:
                            Memorized channels can be scanned by simply pressing this key. "MEMO"
                            blinks and the memorized channels are scanned one by one in an upward
                           direction. This operation is invalid if no channel is stored in the memory.
                        Memory Clear:
                           To cancel a memorized channel, select the channel to be cleared. Then hold
                           the key down until a beep sounds ( approx. 2 seconds). "MEMO" will
                           disappear from the LCD.


                           * Usage of this key in the DSC mode is explained in the DSC section.


) DW/TRI Key:           There are two kinds of scan mode; Dual watch and Tri—watch.
                        First pressing of this key selects Dual watch, and pressing again leads to Tri—
                        watch..


   1W/25W Key:          Alternately changes the transmitter output power between 1 watt ( "LOW"
                        appears ) and 25 watts ( "LOW" disappears).
                        USA channels 13,17,67 and 77 are automatically set to 1 watt, but channels
                        13 and 67 can be switched to 25 watts if 1/25 key is pressed while PTT switch
                        is on.


© CALL Key:             Selects DSC operation. See the DSC section for details.


   DISTRESS Key:        Remove the cover, press the key once, then press for 3 seconds or more to
                       send the distress call transmission using the DSC function. See the DSC section
                       for details.


M 16/9 Key:             Works same as (3) 16/9 Key.


) UP/DWNAwKey:       Selects channels. Also selects functions in the DSC operation.


13 PTT Switch ( Push—to—Talk):    Hold this switch down to transmit, and release it to
                        listen. "TX" appears during transmission.

3. DSC (Digital Selective Calling) Operation
     This device complies with RTCM SC101—STD.


 3—1: Transmitting DSC ( Digital Selective Calling) Calls
   This radio is equipped with the DSC function necessary for maritime traffic.


   * Distress Call


    The Distress Call automatically sends the information including the vessel‘s DSC
    MMSID (Maritime Mobile Service ID) and Lat/Lon position.
    Note: It is necessary that the radio is connected to GPS or LORAN to send the
          vessel‘s position.


     1. Remove the cover and press the DISTRESS key. CH7O, AYOS             and

       "DST" will appear On the display.
    2. Press the key again (for about 3 seconds) and "TX" will appear.
    3. After the distress signal has been sent, an alarm is sounded, and the radio
       dual— watches between CH16 and CH7O until an ACK is received. ("DST" blinks)

             Transmission is repeated at the interval of 3.5min to 4.5min until an ACK signal is received.
             To quit this mode, press 16/9 key.


     4. If an ACK signal is received, "ACK RCV" appears, the channel goes to CH16
        automatically, and the Distress Alarm is sounded. To stop this Distress alarm,
        press any key.
