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 turned 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 second function.

       SQUELCH - sets the squelch level to block weak signals.

          TUNE - selects a frequency.

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 possess 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.
