  • Charging time varies depending on the usage conditions of the built-in rechargeable battery.

  • Charge the microphone or receiver in an ambient temperature between 5 °C and 35 °C (41 °F and 95 °F). Be aware that room temperatures may fall to 5 °C (41 °F) or lower depending on the season, especially during winter.

  • The microphone and receiver may become warm during charging. However, this is not a malfunction.

  • Avoid sudden temperature changes, direct sunlight, mist, sand, dust, and electrical shocks. Also, never leave the microphone and receiver inside a parked car.

  • The microphone or receiver can be charged even if the power is on, as long as it is connected to a power outlet using a USB AC adaptor. However, depending on usage conditions, charging time may be longer. For optimal charging, it is recommended to turn off the microphone or receiver.

  • Charging will stop in environments with extremely high or low temperatures for safety reasons. Additionally, charging may stop if it continues for an extended period. To resume charging, disconnect and reconnect the USB cable within the usable temperature range of 5 °C to 35 °C (41 °F to 95 °F).

  • If the built-in rechargeable battery experiences a high load during charging, charging will stop for safety reasons. In such cases, stop using the microphone or receiver.
