Concise Introduction to the 2870 LED Multi-Sensory Interactive Game Device

Core Highlights

• Two Modes & Two Speeds: Supports Challenge/Training Modes (long-press the ON button for 3 seconds to switch, with corresponding indicator light flashing for prompt). Both high and low speeds are adjustable (defaults to low speed on startup; press LEFT/RIGHT buttons to cycle through), catering to diverse needs.
• 99-Level Progressive Gameplay: Touch the corresponding indicator lights in sequence to clear a level and advance automatically. In Challenge Mode, failure results in a 1-level downgrade; in Training Mode, you can restart the current level after a failed attempt.
• Audio-Visual Dual Feedback: The fast mode triggers the "Do Re Mi" musical tune on activation, while button presses in slow mode produce fixed sound effects. The three function buttons (LEFT/RIGHT/ON) are paired with green, yellow, and red indicator lights respectively; all three lights flash for 6 seconds as a prompt upon failure.
• Intelligent Low-Power Design: A dual-digit dual LED screen displays the current level and highest record in real time. Auto-shuts off after 1 minute of inactivity, with a shutdown power consumption of only 7uA. It supports a wide voltage range of 2.1V–3.0V (powered by 2 AA batteries).
