How do I connect the RP750x reader to my device?

There are two ways to connect the RP450c reader:

Audio Jack
Connect the RP450c reader by inserting the stem of the reader into the audio jack of your mobile device. The jack is detachable from the RP450c unit, and can be inserted to either of the reader’s ports based on the location of the audio socket on your mobile device.

Pairing via Bluetooth
The audio jack head is a detachable unit from the reader. Unless you are using the reader primarily using the audio jack, the audio jack head will be used just for initial Bluetooth pairing. Once paired, the audio jack can be stored securely. To do this, follow the instructions below:

10. If the code matches, the application will begin pairing with your reader.  Important: While Pairing or Setting up process is in progress:  The “Disconnected Reader + Spinner” animation will be shown to the user in the app’s header AND the Text under the reader in My Readers will be Connecting… (The entire Reader row and the Info icon will not be tappable)

11. Only after the reader is ready to accept transactions (after Setup) the following events will happen at the same time:
• The “Disconnected Reader + Spinner” animation will be replaced by the “connected reader” icon AND
• The Connecting… text on the Reader row will be replaced by Connected.
