the VU meter for "Microphone (USB Voice CODEC) on the Recording tab, then click OK.
11. Return to the Playback tab, double click "Speakers (USB Voice CODEC)," select the Levels tab and
adjust the microphone to the same level you set in the previous step.
12. Turn on VOX and speak into the microphone. Using the R1 trimmer, set the same drive level as you set
in step 12 on page 66 - do not adjust the MIC GAIN on the radio.
NOTE: To make fine adjustments, you can compare levels for the direct ("A") connection and through
the sound card ("Cm") by pressing the footswitch or hand mic PTT. When the radio is keyed by VOX or
MOX, the microphone audio is passing through the sound card. When the radio is keyed by the
footswitch or hand mic PTT, the microphone is connected directly to the radio.
13. If you cannot balance the direct and sound card levels with the trimmer, return it to the midpoint, click on
"Balance" in the "Speakers (USB Voice CODEC)" Levels tab and adjust the Left level. Then use the
trimmer for fine adjustment.
