DH280 Mouthpiece and Drain
The DH-280 shares the side drain concept with the top-of-the-line DH500.
When I replaced the voice circuitry in the DH-280 with that from an old DH-100, I had to also bring the breath sensor from the old DH-100. I think the diaphragm coils had different impedances between models.
