ASIC Heatsink Heat‑pipe based heatsink designed to efficiently cool the core hashing chips. Power Chip Heatsink Independent cooling structure that reduces temperature of power management chips for better long‑term stability. Interface Area DC Jack power connector + Status indicator LED. ️ Important: Do not block the air intake or exhaust vents. Ensure proper airflow at all times. ️ Installation & Power‑On Place the device on a stable and well‑ventilated surface. Connect the included 5V/8A power adapter to the DC Jack. Plug the adapter into a standard AC outlet (100‑240V). The device will start automatically – the fan will spin and the LED will indicate status. Caution: Do not plug or unplug the DC Jack while the device is powered on. Use only the supplied 5V/8A adapter – third‑party adapters may cause damage. Network Configuration (WiFi 2.4G & RJ45) The device supports WiFi 2.4G and RJ45 wired connection. Network configuration is completed via the web management interface after power‑on. Connect to the miner&#x27;s hotspot or use Ethernet to access the setup page. ️ Mining Modes SOLO Solo mining – earn full block reward when a block is found. PPLNS Pay Per Last N Shares – rewards based on contributed shares. PPS Pay Per Share – stable payout per valid share. Cooling & Noise The PWM fan automatically adjusts speed based on temperature. Typical operating noise is below 40 dB – quiet for home use. Increased fan speed under high load is normal . Frequently Asked Questions Q1: Is hashrate fluctuation normal? A: Yes. Hashrate variation within ±5% is normal due to network and temperature conditions. Q2: The fan is loud after startup – is that normal? A: Yes. During startup or under heavy load, the fan may run at higher speed temporarily to cool the chips. This is normal behavior. Q3: What power supply do I need? A: Use the included 5V/8A adapter. Do not use any other adapter – it may damage the device. Q4: Can I use the device in a closed cabinet? A: No. Enclosed spaces restrict airflow and may cause overheating or shutdown. Place in open, ventilated area. Q5: Will the miner resume mining after a power outage? A: Yes. If network and pool settings are saved, the device will automatically resume mining when power is restored. Q6: Does it support 5G WiFi? A: No, it supports 2.4G WiFi and RJ45 Ethernet. Q7: What should I do if the device cannot connect to the network? A: Check that your WiFi is 2.4G, verify signal strength, and ensure the network is stable. Try using Ethernet if issues persist. Q8: Does the device guarantee mining profits? A: No. Mining profitability depends on network difficulty, pool rules, electricity costs, and market conditions. ️ Safety Notice Do not disassemble or modify the device. Do not block the cooling airflow. Do not use the device in humid or high‑temperature environments. Power off immediately if abnormal behaviour occurs. Only use the supplied 5V/8A adapter – other adapters may cause fire or damage. Warranty & Disclaimer 6‑month warranty – void if disassembled, modified, using unofficial firmware, or damaged by improper use (including third‑party adapters). No after‑sales service for unauthorised modifications. Users are responsible for complying with local laws regarding cryptocurrency mining. Mining results are not guaranteed and may vary due to network difficulty, pool performance, and market factors. The manufacturer is not liable for pool access or network issues. Specifications may change without notice. Gamma 602 – Desktop SHA‑256 ASIC Miner Production Version V1.0 • Designed for enthusiasts and home miners.
