This article explains how to pair a Bluetooth device with an iPad and how to forget a paired device.

The process of pairing a Bluetooth device ensures that the communication between the device and the iPad is encrypted and secure. Security is essential because phone headsets are a popular Bluetooth accessory and you don't want someone to easily intercept the signal when you're using them for a call.

Bluetooth also lets iPad remember the devices you pair with it, so you don’t have to go through the setup process every time you want to use the accessory. It connects to iPad the moment you turn it on.

Open the iPad settings by launching the Settings app.
