Pulsar 590/590A Troubleshooting: Low Transmit Volume
People cannot hear me well during phone calls. What can I do about this?
The microphone boom of the Pulsar is a clear voice tube. These voice tubes have a very thin micro filter that can become clogged from moisture combined with dust. If your voice is not transmitting well, you can gently pull the voice tube off of the Pulsar headset and replace it with one of the spares that comes with the Pulsar travel case. You can also order additional voice tubes from one of our distributors. The part number is 70903-01.
