Charging the microphone and receiver

You can charge the microphone and receiver by connecting a commercially available USB AC adaptor and the supplied USB Type-C cable to a power outlet.

When using the microphone and receiver for the first time, charge them for at least 1 hour before turning on the power.

After charging the microphone and receiver, you can use them with the built-in rechargeable batteries only.

Recommended USB AC adaptor

Use a commercially available USB AC adaptor with an output of 5 V 0.5 A (500 mA).

  1. Connect the microphone or receiver to a power outlet for charging.

    Use the supplied USB Type-C cable to connect the DC input port of the microphone or receiver to a USB AC adaptor. Then, connect the USB AC adaptor into a power outlet.

    The charge indicators on the microphone and receiver light up in orange while charging is in progress. The indicators turn off when charging is complete.

    It takes approximately 2.5 hours (*) to fully charge the built-in rechargeable battery from an empty state when the microphone or receiver is turned off.

    (*) This is the estimated time when using a commercially available USB AC adaptor with an output of 5 V 0.5 A (500 mA).

How to check if the built-in rechargeable battery is fully charged

Connect the microphone or receiver to a power outlet using a commercially available USB AC adaptor. If the built-in rechargeable battery is fully charged, the charge indicator will light up in orange and turn off approximately 1 minute later.

Charging time for the built-in rechargeable battery

  • Microphone

    Approximately 2.5 hours (*)

    A 10-minute charge provides approximately 120 minutes of use.

  • Receiver

    Approximately 2.5 hours (*)

    A 10-minute charge provides approximately 120 minutes of use.

(*) This is the estimated time required to fully charge the built-in rechargeable battery from an empty state under the following conditions.
The microphone or receiver is turned off.
A commercially available USB AC adaptor with an output of 5 V 0.5 A (500 mA) is used.

Note

  • The charging time depends on the output current of the commercially available USB AC adaptor. Additionally, the types or specifications of the USB AC adaptor and USB cable may result in a longer charging time than the one mentioned above. Charging time may also vary depending on the surrounding temperature and usage conditions.


The above times are measured using the company's specified audio source.

Charging and usage times may vary depending on the surrounding temperature and usage conditions.

Hint

  • 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.

  • The microphone or receiver can also be charged by connecting it to a speaker with a USB charging-compatible port. However, this does not guarantee compatibility with all speakers.

Note

  • Depending on the types or specifications of the USB AC adaptor, the remaining power of the built-in rechargeable battery may decrease or the power may turn off even when the microphone or receiver is connected to a power outlet. This is not a malfunction. In such cases, turn off the power and fully charge the microphone or receiver before use.

  • 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.

  • The microphone and receiver are not designed to be waterproof or dustproof. Depending on how they are used, water or dust may get inside, potentially causing fire, electric shock, or malfunction. Be careful to avoid exposure to moisture or dirt.

  • If you are not going to use the microphone or receiver for an extended period, charge it once every 6 months to prevent the deterioration of the built-in rechargeable battery.

  • When charging the microphone or receiver via a speaker, be sure to connect or disconnect the USB cable while the speaker is turned off.
