    Tone remote 1 1 general unless noted, this manual refers to dsp-223 operating software 2.6. The vegadsp-223 tone-remote adapter provides remote control of two-way-radio base stations using any vega tone remote consoles. The dsp-223 is also compatible with other consoles using the industry- standard ...
