Welcome to the world of "Self-Custody"! Experience unparalleled security by taking full control of your digital assets. By choosing OneKey Classic 1S Pure BTC-Only, you prioritize the security of your Bitcoin. This model is perfect for HODLers, as "Pure" means "no battery" to eliminate long-term battery degradation issues, and "BTC-Only" signifies firmware specifically designed for Bitcoin, thereby minimizing vulnerabilities from supporting other coins and unnecessary code.

This guide will simplify the steps and walk you through them one by one.

1. Initial Instructions and Requirements

Precautions before use

Before starting the setup process, it's crucial to inspect the packaging and holographic seal to ensure that your device has not been tampered with by others. If you find any signs of tampering, immediately stop using the device and contact Bitcast for assistance and a prompt replacement.

• Carefully note "Word #1" ensuring both the order and spelling are correct.
• Repeat this step for all 12-24 words you selected earlier.

Security Recommendations (Seed Phrase)

• Your Recovery Phrase (or Seed Phrases) must be kept secure, as it is the sole key that can recover your assets.
• Do not create digital copies of your Seed Phrases and never upload them online.
• Store it in the safest possible place, accessible only to you or individuals you implicitly trust.

Step 3: Review and Confirm Recovery Phrase

• When the screen displays "Check Words Again," verify and compare the words you wrote on the Seed Phrase sheet with the words shown on the OneKey device to ensure the order and words match.

• Repeat this step until the message "Awesome! Your backup is complete." appears.

Step 4: Set a PIN Code

• Select your PIN digits (1 to 9, no 0).
• If setting only 6 digits, select ☑️ in the 7th position to confirm.
• Enter the PIN again to confirm.

• When the screen displays "Wallet is ready! Download ....", it means the hardware wallet setup is complete. Please follow the on-screen instructions and proceed to the next step (Step 5).
