    MK4000 Scanner Volume

      I have set the Volume using EMML, Javascript, and the meta tag for volume.

      I even set Control Panel sound levels.  I still get the ear splitting MK4000 scan beep. 


      What is the best way to control scanner volume short of stuffing cotton and superglue in the speaker?

          Hi Carl


          Have you tried changing the scan frequencies and volume in the config file?

            Hello Carl,


            The value of below XML tag of Config.xml can be changed to control the scan beep volume


            <DecodeVolume          VALUE="1"/>

            <DecodeFrequency     VALUE="0xBB8"/>

              Tried the Config.xml.  Even rebooted.  No change in beep volume.


                      <DecodeVolume             value="1"/>

                      <DecodeFrequency        value="0xBB8"/>

                      <InvalidDecodeFrequency value="0x9C4"/>

                      <DecodeDuration           value="250"/>

                      <ScanDecodeWav          value=""/>

                      <ScanInvalidWav             value=""/>

                      <ImagerCaptureWav       value=""/>



              Also tried javascript - No change in beep volume.


                  function doSoftScan()



                      notification.setBeeperFrequency = 1500;




              Why is it the little things that make one consider being a greeter at WalMart?

              I have more time invested with beeps than I did courting my wife.  Sheesh.

                Changing frequency works.

                Changing duration works.

                Changing volume does nothing.... wait .... ran it up to 3  ... GEEZ!  The PAIN!

                Apparently a volume of 1 is still darn loud.  0 is silent.

                Changing volume works in Config.XML.


                If someone needs to have a lesser volume on an MK4000, lowering the frequency and duration is the technique.
