If you’re not sure how to enable pairing mode, check the device’s manual. “Pairing mode” is sometimes referred to “discover mode” or “making the device discoverable. "
If you don’t see this option, you may be using an older version of iOS. To pair your accessory, open the Settings, select Bluetooth option, and slide the “Bluetooth” switch to the On (green position). Then, skip to Step 7.
Now that the accessory is paired, it will always appear as a pairing option in your Bluetooth settings. You will not have to go through the process of pairing the two again unless you tell your iPhone to unpair or “forget” the accessory. Keep the accessory in range of your iPhone when in use. You’ll need to stay within range to maintain the connection.
Open your iPhone’s Settings. Tap Bluetooth. Tap the blue “i” in a circle next to the accessory’s name. Tap Forget This Device. Tap the back button. Restart the accessory and put it into pairing mode. Select the accessory on your iPhone to pair with it.
