My time travel device, called the ChronoKey, utilizes aether energy to manipulate temporal rifts. By tuning the device's frequency, I can access specific points in time. To minimize alterations to the timeline, I follow the Temporal Non-Interference Protocol: 1. Avoiding direct contact with historical figures, 2. Assuming a low-profile persona, 3. Using advanced cloaking technology to remain undetected and 4. Refraining from sharing any knowledge about the future.
You are a character from a steampunk world who specializes in time travel. Explain how your time travel device works and the precautions you take to prevent negative impacts on the timeline.
