(190-1110A)                Operation                  Faxback Doc. # 60264

A Quick Look at the Controls

    OFF/VOLUME - turns the radio on/off; adjusts the volume.

    RF-G/MIC-G - attenuates strong signals; reduces the microphone's gain
                 and SSB transmitting power.

     STEP/NB/1 - selects the frequency tuning step; turns the noise
                 blanker on/off; selects memory Channel 1.

        CALL/2 - quickly recalls a frequency in memory Channel 2; selects
                 memory Channel 2.

  SCAN/SHIFT/3 - starts/stops scanning; selects the frequency shift;
                 selects memory Channel 3.

         LCR/4 - recalls the last tuned channel; selects memory Channel 4.

  MODE/T-LOW/5 - selects the operation band, AM/FM/USB/LSB; turns hi-cut
                 filter on/off; selects memory Channel 5.

 M-LOAD/M-SAVE - loads from/saves to a memory location.

FINE/PUSH FUNC - adjusts fine tuning; activates sound function.

       SQUELCH - sets the squelch level to block weak signals.

          TUNE - selects a frequency.

Operation

Setting Squelch and Receiving

1.  Rotate SQUELCH fully counterclockwise.

2.  Rotate RF-G fully clockwise.

3.  To turn on the transceiver, rotate OFF/VOLUME clockwise until it
    clicks.  The display lights and the frequency appears.  A bar graph
    also appears which shows the received signal's strength.

4.  Set OFF/VOLUME to a comfortable listening level.

5.  Rotate SQUELCH clockwise until you hear a hissing sound.  Then slowly
    rotate SQUELCH counterclockwise just until the noise stops.

    Note: If the transceiver picks up unwanted weak transmissions, rotate
          RF-G slightly counterclockwise to decrease the transceiver's
          sensitivity to signals.  The transceiver blocks the weak
          transmissions.

6.  Repeatedly press MODE to select the desired band (FM, AM, USB (upper
    sideband), or LSB (lower sideband).

7.  Rotate TUNE or press UP or DN on the top of the microphone to select a
    frequency.

8.  To turn off the transceiver, rotate OFF/VOLUME counterclockwise until
    it clicks.

Transmitting

Notes: Do not attempt to transmit unless you posses a valid amateur radio
       license.

       We recommend you try receiving before you transmit.

1.  Follow Steps 1-7 in "Setting Squelch and Receiving," above.

2.  Turn MIC-G fully clockwise.

3.  To transmit, hold down the push-to-talk button on the microphone, hold
    the microphone 2-3 inches from your mouth, and speak in a normal tone
    of voice.  TX appears along with a bar graph which shows the strength
    of your transmission.

4.  When you finish transmitting, release the PTT button.  TX and the
    signal strength bars disappear.

5.  To turn off the transceiver, rotate OFF/VOLUME counterclockwise until
    it clicks.

Notes on SSB Reception

If the voice sounds distorted, slowly rotate FINE to bring the signal into 
its natural voice tonal range.

An SSB signal produces a fluttering, unintelligible sound when received in 
the AM mode.  Set the mode switch to either LSB or USB, and adjust FINE.  
If the voice is still not intelligible, it might be an SSB signal 
operating on the other sideband - try the other SSB mode.
