Otherwise, you will have to turn up the volume of the headphones, and that may cause noise. ⷠWhen you connect the connecting cord directly to an earphone jack (monaural mini jack), the audio signal may not be output through the right channel. In such a case, use the separately sold PC-236MS plug adaptor (stereo mini jack y monaural mini plug) between the connecting cord and the earphone jack.

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. Set the VIBRATION switch to ON and adjust the level of vibration using the vibration volume. You can enjoy powerful bass sound when you listen to movies or games through the headphones.
