# E300 Setup Guide

> [!CAUTION]
> TOP TIP: Push the power plug all the way in. The most common reason an E300 won't turn on is a power plug that isn't fully seated. The plug and the power port both have small notches inside. If they aren't lined up, the plug can feel secure when it isn't. See Step 4 below.

## Introduction

### About this User Manual

Please read this user manual carefully and keep it for future reference. Pictures in this manual may differ slightly from your player because of continuous updates.

### Product Overview

The Skykit E300 is a compact, fanless media player built for 24/7 digital signage. It's small enough to mount behind a display or inside a kiosk, plays content at up to 4K, and connects to your network over Ethernet or Wi-Fi. The E300 is TAA compliant, so it meets sourcing requirements for government and other procurement-driven deployments.

### Intended Use

The E300 Media Player is intended for commercial use to power digital signage content on a single display, with reliable 24/7 operation.

### Key Features

- Up to 4K (4096 × 2160) output at up to 120 frames per second
- Ultra-thin, fanless design for silent 24/7 operation
- Gigabit Ethernet, dual-band Wi-Fi 5 and Bluetooth 5.1
- Hardware video decoding for AV1, H.265 (HEVC), H.264, VP9 and AVS2
- 6 TOPS NPU
- TAA compliant, CE and FCC certified

## Quick Start Guide

### Step 1: Unbox your Skykit E300 Media Player

Check that the box contains everything listed in **Unboxing and Package Contents** below. You'll also need an HDMI cable, an Ethernet cable if you're using a wired connection, and a USB keyboard and mouse if you need to set up Wi-Fi manually.

### Step 2: Position the player

Place or mount the E300 behind the display, inside a kiosk or on a flat surface. Because the E300 is fanless, it cools through its case. Leave space around it for airflow and avoid enclosed spaces that trap heat.

### Step 3: Connect HDMI and network

1. Connect an HDMI cable from the **HDMI** port on the back of the E300 to your display. Turn the display on and set it to the matching HDMI input.
2. For a wired connection (recommended), connect an Ethernet cable from the E300's **Ethernet** port to your router or network switch. If you're using Wi-Fi, you'll set it up in Step 5.
3. If you need to set up Wi-Fi manually, plug a USB keyboard and mouse into the USB ports on the side of the player.

> [!NOTE]
> Check your firewall
> 
> If your network restricts outbound traffic, make sure the player can reach Skykit's services. See [Network Firewall Configuration for Skykit](https://support.skykit.com/docs/network-recommendations).

### Step 4: Connect power

1. Plug the power adapter into a wall outlet.
2. Look at the end of the power plug. You'll see small notches inside the tip.
3. Line the plug up with the **DC-IN** port on the back of the E300 and push it in firmly.
4. Check that the metal part of the plug is fully inside the port. If you can still see the metal barrel (shown by the arrow below), the plug isn't fully seated. Rotate the plug slightly until the notches line up, then push again.

The E300 turns on automatically when it receives power. If it doesn't, press the power button on the front.

> [!CAUTION]
> Use the included power adapter
> 
> Other adapters, including ones with the same plug size, may not supply the right power.

### Step 5: Configure Wi-Fi (if needed)

If you're using Wi-Fi and the player wasn't preconfigured, follow **Wi-Fi Setup** below.

### Step 6: Start displaying content

Once the player is online, [sign in to your Skykit account](https://support.skykit.com/docs/signing-into-your-skykit-account), pair the player and publish content with Skykit Beam. Your sign-in details are in your welcome email. If you don't have them, contact [support@skykit.com](mailto:support@skykit.com).

See [Why won't my E300 device power on?](https://support.skykit.com/docs/why-won-t-my-e300-device-power-on) If it still won't turn on, contact [support@skykit.com](mailto:support@skykit.com).

#### The display shows "No signal"

- Check that the display is set to the correct HDMI input.
- Reseat the HDMI cable at both ends.
- Try a different HDMI cable.

#### The player isn't showing up as online

- For Ethernet, check the cable at both ends and confirm the port on your switch or router is active.
- For Wi-Fi, repeat the Wi-Fi setup steps and check the password.
- Confirm your network allows the player to reach Skykit's services. See [Troubleshooting Connectivity Incidents](https://support.skykit.com/docs/troubleshooting-connectivity-incidents).

## Precautions Before Use

- Use only the power adapter supplied with the player.
- Keep the player within its operating temperature range and away from enclosed spaces that trap heat.
- Don't block the case. The E300 is fanless and cools through its surface.
