[FAQ-1223] Error message: LOW VOLUME (Code 46)

Page Type: SYMPTOM


The LOW VOLUME warning means that, when the scanner is set to a test condition where it receives static, the observed audio level is less than 40% of full volume. If the input levels are too low, the audio recordings may have lower quality. And in the extreme case, the Rangecast software may not be able to automatically detect that the audio port is associated with a particular scanner, rendering the scanner inoperative.


Raise the audio levels in Windows Sound for the audio input from the scanner.

[FAQ-1067] Adjusting Windows audio input levels

The Rangecast audio recording process compresses audio to support a wide dynamic range, but if the levels are too high or low, quality is compromised (and some transmissions may even be discarded). A level control is available in Windows Sound to adjust the input levels from each scanner, and Rangecast provides information about observed levels to help determine when adjustments are needed.

It is recommended that the audio levels be checked on all scanners connected to this PC. When one scanner shows a "Low Volume" error, it is not uncommon for other scanners to have marginal quality audio levels (low, but not low enough to raise an alarm) that would benefit from adjustment. It is easy to check and correct the audio levels on all scanners connected to a single PC at the same time.
