Sending RF signals from the transmitter

The transmitter starts sending RF signals automatically when it detects an audio signal from the equipment connected.

If it does not detect an audio signal for more than about four minutes, the transmitter will stop sending RF signals, and the power indicator will turn off.

When the transmitter receives an audio signal again, it starts sending the RF signals, and the power indicator will light in red again.

If the audio signal is very weak, the transmitter does not send RF signals. If the transmitter is connected to a headphone jack, make sure the volume of the equipment connected is set to 5 – 6 or higher.

You may not hear the beginning of the sound from the headphones until the transmitter starts sending the RF signals after detecting an audio signal.

The headphones automatically turn off when they are taken off— Auto power on/off function

Do not pull up the self-adjusting band when not in use, as this will consume the battery power.
