Tips for volume setting
I cannot turn the Headphone on
If you connect the transmitter to the headphone jack of the A/V component, set the volume of the A/V component
as high as possible but not so high that the audio signal becomes distorted.
When watching videos, be careful not to raise the volume too high in quiet scenes. You may hurt your ears
when a loud scene is played.
Replace the batteries in the headphone, and make sure the switch is in “ON”
Tips for better reception
Receiving performance
This system utilizes signals in the 88-40MHz band so the receiving performance may
deteriorate due to the surroundings. The following examples illustrate conditions that may reduce the reception
range or cause interference.
- Inside a building with walls containing steel beams.
- An ares with many steel file cabinets, etc.
- An area with many electrical appliances capable of generating electromagnetic fields
-The transmitter is placed on a metal instrument.
- An area facing a roadway
- Noise or interfering signals exist in the surroundings due to radio transceivers in trucks, etc.
- Noise or interfering signals exist in the surroundings owing to wireless communication systems installed along
roadways.

To reduce the risk of fire or electric shock, do not expose this apparatus
to rain or moisture.
To reduce the risk of fire or electric shock, do not expose this apparatus to dripping
or splashing, and do not place objects filled with liquids, such as vases, on the
apparatus.
Do not expose the batteries (battery pack or batteries installed) to excessive heat
such as sunshine, fire or the like for a long time.
To avoid electrical shock, do not open the cabinet. Refer servicing to qualified
personnel only.

cabinet.
As the main plug of AC power adapter is used to disconnect the AC power adapter
from the mains, connect it to an easily accessible AC outlet. Should you notice an
abnormality in it, disconnect it from the AC outlet immediately.
Excessive sound pressure from earphones and headphones can cause hearing
loss.
Effective area of the transmitter
The optimum distance is up to approximately 9.1 m( 30ft) without the system picking up some interference.
However, the distance may vary depending on the surroundings and environment.
- If the system picks up some noise whthin the above mentioned distance, reduce the distance between the
transmitter and the headphones, or select another channel.
- When you use the headphones inside the effective area of the transmitter, the transmitter can be placed in any
direction from the listener.
- Even within the signal reception area, there are some spots (dead spots) where the RF signal cannot be received.
This characteristic is inherent to RF signals, and does not indicate malfunction. By slightly moving the transmitter,
location of the dead spot can be changed. or straighten the audio cable between transmitter and device.
