This guide covers RADR's settings menu, WiFi configuration, and power management options.

## Accessing Settings

From the main menu, select **Settings** to access the settings menu.

## Settings Menu Options

| Option         | Description                            |
| -------------- | -------------------------------------- |
| Go Back        | Return to the main menu                |

### Navigation

* **Right Encoder** — Scroll through options

## WiFi Configuration

WiFi connectivity enables over-the-air (OTA) firmware updates for your RADR.

<Info>
  WiFi is optional and primarily used for firmware updates. RADR's core functionality (device control) works entirely over Bluetooth.
</Info>

### Setting Up WiFi

<Steps>
  <Step title="Open WiFi Settings">
    From the settings menu, select **WiFi Settings**.
  </Step>

  <Step title="Connect to RADR's Access Point">
    RADR creates a WiFi access point called **"RADR Setup"**.

    A QR code is displayed on screen for easy connection:

    ```
    WIFI:S:RADR Setup;T:nopass;;
    ```

    Scan the QR code with your phone, or manually connect to the network:

    * **Network Name:** RADR Setup
    * **Password:** None (open network)
  </Step>

  <Step title="Configure WiFi Credentials">
    Once connected to RADR's access point, a configuration portal opens automatically:

    1. Select your home WiFi network from the list
    2. Enter your WiFi password
    3. Save the configuration
  </Step>

  <Step title="Confirmation">
    After successful configuration, you'll see the **"WiFi Connected"** screen:

    * **Message:** "Your OSSM Remote is now connected to WiFi."
    * RADR is now ready to receive OTA updates
  </Step>
</Steps>

### WiFi Configuration Details

| Parameter         | Value              |
| ----------------- | ------------------ |
| Access Point Name | RADR Setup         |
| Security          | Open (no password) |
| Portal Timeout    | 30 seconds         |
| Retry Attempts    | 5                  |

<Warning>
  The WiFi setup portal has a 30-second timeout. If the portal times out, restart the WiFi Settings process.
</Warning>

## Update Device

Select **Update Device** to check for and install firmware updates.

<Note>
  This feature requires WiFi to be configured. Updates are downloaded and installed over-the-air.
</Note>

## Restart Device

Select **Restart Device** to reboot your RADR. This is useful for:

* Clearing temporary issues
* Applying certain settings changes
* Resetting the Bluetooth state

The device will power off and restart automatically.

## Sleep Mode

From the main menu, select **Sleep** to enter deep sleep mode.

### What Happens in Sleep Mode

1. RADR disconnects any connected devices
2. A shutdown sound plays
3. The display turns off
4. LEDs turn off
5. The device enters ultra-low power mode

### Waking from Sleep

Press any of the three under-screen buttons to wake RADR:

* Left button
* Middle button
* Right button

<Info>
  When waking from sleep, RADR performs a full restart and returns to the main menu.
</Info>

### When to Use Sleep Mode

Use sleep mode when:

* You're done using RADR but don't want to fully power off
* You want to conserve battery between sessions
* You want a quick way to pause without disconnecting the power switch

<Tip>
  For extended storage, use the physical power switch instead of sleep mode. Sleep mode still consumes minimal power.
</Tip>
