Just by placing the headphone unit on the transmitter, the headphone unit battery can be charged. ● AUTO ON/OFF function is equipped with the transmitter. ● AUTO OFF function is equipped with the headphone unit. ● ENHANCING SPEECH is a function to enhance human voice for speech intelligibility.

What are bone conduction headphones?

While ordinary headphones convey sounds through the eardrums, bone conduction headphones convey sounds by conducting vibrations directly to the auditory ossicles and cochlea through the skull. Since they do not cover the ears, you can enjoy music coming from the headphones and still hear sounds from the surrounding environment. This feature reduces the strain on the eardrums as compared to ordinary headphones that cover the ears. Skull

This unit uses radio waves. The waves can be transmitted to a range of up to 100 meters. Note

Under optimum conditions, the headphone unit can pick up clean signals from the transmitter to a maximum of

100 meters. Metal between the two units and the presence of other radio waves may cause interference to occur at a shorter distance. This interference can be cleared by moving closer to the transmitter, removing the obstructions, or changing the transmitter channel. You may occasionally experience interference due to dead spots in the area covered by the transmitter. This phenomenon occurs with any kind of radio signal and is not a malfunction. Dead spots can be moved by moving the transmitter and the headphone unit.

Recharge the battery before using the unit.

1. Connect the supplied AC adaptor to the transmitter, and then to a household mains socket. (AC 230 V - 240 V, 50 Hz) 2. Mount the headphones on the receiver. Insert the plug on the headphones to the jack on the receiver, and connect them. (The headphones connected to the receiver are hereinafter referred to as “the headphone unit”.) 3. Place the headphone unit in the transmitter. Put the headphone unit correctly, with [OPR] indicator toward you, and place it in the transmitter. Press the headphone unit down gently, and make sure [OPR/ CHG] indicator will light up in red.

How to put the headphone unit

AUTO ON/OFF function

When the transmitter receives audio input, the power is turned on ([OPR/CHG] indicator lights up in green).

When the transmitter has not received audio input for approximately 3 minutes, the power is automatically turned off ([OPR/CHG] indicator goes out). When the volume of the connected unit is too low, this function doesn’t work. Turn up the volume as much as possible without causing distortion. Note

Even if the transmitter’s power is automatically turned off, some noise may be generated when the headphone unit is still on. This is not a malfunction.

If reception is still poor

Interference may occur between the radio waves from the transmitter and other radio waves. You can change the transmitter channel to improve reception. If you use the unit near a cordless telephone, it may cause radio interference.

Before changing the transmitter channel: Make sure that the headphone unit is turned off.

1. Hold the headphone unit correctly, with [OPR] indicator outward.

2. Slowly expand the arms, and put the right and left speakers. ● Do not excessively pull the arms apart. Put the bone conduction headphones 3. Hang the hook on the tragus (triangle part) . This will give you the most appropriate position. ● If you put the headphones in the incorrect position, you may not hear sounds well from the speakers and the surrounding environment. Put the In-Ear headphones 3. Insert the earpieces into ears. ● If earpieces do not fit your earholes properly, a low pitch could not be heard due to the decreased sealing property. In order to enjoy higher quality sound, insert earpieces farther into the ears by turning them slightly. ● If earpieces do not fit to your earholes, replace them with other earpieces sets supplied.

1. Select another channel with [CHANNEL] switch.

/TUNING] button to adjust the 2. Press [POWER frequency automatically.

How to replace the headphones

Some sound or noise may still be heard even if no sound signals are passing through the transmitter.

ENHANCING SPEECH See illustrations

ENHANCING SPEECH can be used to make human voice easier to hear.

1. Make sure that the headphone unit is turned on ([OPR] indicator is red). The function only works when the headphone unit is turned on. 2. Press [ENHANCING SPEECH] button. [OPR] indicator turns to green. The enhancing speech function is enabled. ● To disable the function, press [ENHANCING SPEECH] button again. [OPR] indicator turns to red. ● When the headphone unit is turned off and turned on, the unit starts up with the last enabled/disabled status of the function. Note

When using bone conduction headphones, this function may not be effective.

This unit can be reset if all operations are rejected. To reset the unit, press the end of a thin object, such as a paper clip, into the [RESET] switch on the upper part of the receiver.

Remove the headphones

While pressing and holding the release buttons on the both sides of the receiver, pull out the current headphones from the receiver. Mount the headphones Mount the other headphones on the receiver. ● Insert the plug on the headphones to the jack on the receiver, and connect them.
