Compatibility Notes
-
Accessory Voltage: The Constant Able™ requires a radio that provides accessory voltage at the 6-pin connector. It will not function with radios where this power is absent.
-
DISCUS: Not compatible with DISCUS. DISCUS is designed exclusively for dynamic microphones.
-
U-384 Red Rings: If the downlead on your headset has red rings, you will require the TP-105 O-ring as an addition to this PTT. Red rings typically indicate the U-384 (Dual Comm Split Audio*) configuration.
