#### Overview
This page explains how to register, update, and delete devices, as well as how to operate device management.
1. [**Register a device**](#register-a-device)
[**Update or delete registered device information**](#update-or-delete-registered-device-information)
2. [**Assign devices and register statuses**](#assign-devices-and-register-statuses)
3. [**Manage device usage and history**](#manage-device-usage-and-history)
### Register a Device
Register a new device. You can register devices [manually](#register-a-device-manually), via [MDM integration](/en/it-management/device/k1u975zc6h-mdm), or via [CSV import](/en/it-management/device/dwrsgbckjp-device-csv). Enter device-specific information such as the serial number and model name, and asset information such as the purchase date and price.
#### Register a Device Manually
1. Go to Devices and click **New Device**.
2. On the "Add new device" screen, select a device type. Choose from "PC (Desktop PC / Laptop PC / Tablet PC), Phone (Smart Phone), or Other (Monitor / Other / Peripheral Device / Server)".
3. Enter the required device information and click **Apply**. For a list of input fields, see [Device Management Field Reference](/en/it-management/device/qlla5169py-devicetype#device-management-field-reference). To add custom fields, see [Add Custom Management Fields](/en/it-management/device/2gdbiob664-device-itme#add-a-custom-field).
4. When registration succeeds, the message "Device information has been registered" appears. The device is added under "PC", "Phone", or "Other" according to the selected type.
### Assign Devices and Register Statuses
Assign a user to a device and register its status. For shared PCs and similar devices, assign them to a location instead.
1. Go to Devices, select the device to assign, and click **Change Assignment and Status**.
2. Fill in each field on the "Change Assignment and Status" screen and click **Save**. When you select a status other than "In Stock" or "Disposed / Cancelled", the fields "User / Assignment Date / Assignment End Date" appear. For fields that do not appear, see [Hide Fields](/en/it-management/device/2gdbiob664-device-itme#hide-a-field).
For the **Before Use** status, select "In Use" as the status and set a future date as the assignment date. After saving, the status changes to "Before Use", then automatically changes to **In Use** on the assignment date.
| Item | Description |
| ------------------------------------- | ------------------------------------------------------------------------------------------------------- |
| Status | Select from "In Use / In Stock / Awaiting Delivery / Location Unknown / Broken / Disposed & Cancelled". |
| User | Select the user to assign. Filter by name, email address, or user type. |
| Assignment Date / Assignment End Date | Enter dates manually or select from the calendar. |
| Location 1 / 2 | Enter the location. |
3. The registered information appears under Info > Usage History.
### Manage Device Usage and History
Multiple changes occur throughout a device's lifecycle. Record usage changes as history entries. When conducting an inventory, also refer to [Conduct an Inventory](/en/it-management/survey/duof745x7d-4-survey#inventory-check).
Examples:
* Assignment changes (device user changes due to transfers or resignations)
* Maintenance history (device repairs or replacements)
* Status changes (under repair, scheduled for disposal, etc.)
1. Go to Devices, select the target device, and click **Add History**.
2. Fill in each field on the "Add Usage History" screen and click **Save**. When you select a status other than "In Stock" or "Disposed / Cancelled", the fields "User / Assignment Date / Assignment End Date" appear.
3. The registered information appears under Info > Usage History.
