Warning: Last items in stock!
OPERATION NOTES: Inserting the headphone plug into the connector will provide sound from the headphones only and will automatically disable the detector’s speaker. This automatic speaker-disable feature requires the input impedance of the headphones to be 10,000 ohms or less.
Note that some non-Garrett headphones may not meet this requirement and will require the addition of a 10,000 ohm termination resistor inside the connector to disable the speaker.
