Hardware Installation: 15-Minute Setup

Step 1: Prepare Your TV Surface

Critical for adhesion success:

1. Power off and unplug your TV
2. Clean the back perimeter with isopropyl alcohol (70% or higher)
3. Let dry completely (2-3 minutes)

Why this matters: 90% of LED strip failures come from poor adhesion. Oil and dust prevent proper bonding.

Step 2: Install Fixing Clips

Optimal placement pattern:

• Start at bottom center
• Place clips every 4-6 inches
• Maintain 1-2 inches from TV edge
• Press each clip for 10 seconds

Pro tip: For TVs 55" and larger, use all provided clips. For smaller TVs, space them 3-4 inches apart.

Step 3: Mount the LED Strip

1. Start from the power connector end
2. Press strip firmly into each clip until it clicks
3. Ensure no sagging or loose sections
4. Leave 2-inch gap at corners for smooth bends

Common mistake to avoid: Don't stretch the strip—this damages the LEDs and causes uneven lighting.

Step 4: Cable Connections (The Right Order Matters)

Connect in this exact sequence to avoid HDMI handshake issues:

1. LED Strip → Sync Box

   • USB connector into "LED OUT" port
   • Push until fully seated

2. Source Device → Sync Box

   • Existing HDMI cable into "HDMI IN 1" port
   • Supports up to 4 sources (gaming console, streaming device, etc.)

3. Sync Box → TV

   • Included HDMI 2.1 cable from "HDMI OUT" to TV
   • Use HDMI 2.1 port on TV for 4K/120Hz support

4. Power Connection

   • Connect power adapter last
   • Use surge protector recommended

Compatibility note: Works with any HDMI source but requires HDCP 2.2 for 4K content.

Software Setup: 5-Minute Configuration

Initial Pairing Process

1. Power on sequence:

   • Turn on sync box (LED strip flashes white)
   • Wait for breathing effect (pairing mode active)
   • If no flashing: hold reset button 5 seconds

2. App connection:

   • Download companion app (iOS 12+ / Android 8+)
   • Enable Bluetooth and Wi-Fi
   • Tap "Add Device" when strip is flashing
   • Select your 2.4GHz network (5GHz not supported)

3. Firmware update:

   • App prompts for update on first connection
   • Takes 3-5 minutes
   • Don't power off during update
