# 2-4. Managing Device Types (Add / Edit)
> On the Device Type Management screen, you can add and edit device types used to classify devices.
The top of the device list shows three device categories — **PC**, **Phone**, and **Other**. Each device type is associated with one of these categories.
#### Open the Device Type Management screen
1. Go to Devices and click **Edit device types** in the upper right.
2. The **Device Type Management** screen appears. Here you can edit default items and create custom items (up to 30).
#### Device types
There are two kinds of device types: built-in **default items** and freely created **custom items**.
* Default items: pre-configured items marked with \[Default] in the Type Name column.
* Custom items: items you create by clicking \[+ Add new device type]. You can create up to **30** device types in total.
