Connecting One to External Devices
Most often, if you're connecting to an audio input jack or a mic input, you can use one of the male-male 3.5mm cables provided with your stethoscope. Plug one end into the One and the other into the input jack of your device.
If you're making a recording on a mobile device and want to monitor the output with headphones while recording, use Thinklink (see Thinklink Instructions).
If you're connecting to a device with a "headset" jack (i.e., it provides both microphone input AND headphone output in one 3.5mm jack), use Thinklink, which provides switching to facilitate changing the direction of signals - from the stethoscope to your device for recording and from your device to your headphones for playback.
