Operation Instructions 1. Insert the 18650 lithium battery into the microphone battery compartment, ensuring correct polarity, then close the battery cover. 2. Turn on the microphone power switch. The indicator light will illuminate, and the microphone will automatically enter pairing standby mode. 3. Plug the included receiver into the corresponding input jack of your speaker, sound card, or amplifier. The receiver will automatically pair with the microphone. 4. Once pairing is successful, you can start singing, speaking, or using it for meetings – no additional frequency adjustment is needed. 5. When battery power is low, charge the microphone using a Type-C charging cable connected to a power source. HOW TO CHARGE & PRECAUTIONS V. Charging Instructions The unit features a standard Type-C charging port. The indicator light turns on while charging and automatically changes color or turns off when fully charged. It is recommended to fully discharge the battery before recharging. For first-time use, it is advisable to fully charge the battery before use to protect battery life. Do not overcharge for extended periods. VI. Precautions - Do not use the microphone near high temperatures, high humidity, or in rainy conditions. Prevent water ingress which may damage internal circuits. - When not in use for a long period, remove the battery for storage to prevent leakage that may shorten battery life. - Do not drop or hit the microphone; avoid damaging the voice coil and internal components, which would affect sound quality and signal reception. - Keep away from strong electromagnetic devices during use to avoid interference (noise, disconnection). - Unauthorized disassembly is not permi…
