Try the above steps 2 and 4 until the
receiving performance becomes better.

Sending RF signals from the Transmitter

The transmitter starts sending the RF signals
automatically, when it detects audio signals from
the equipments connected.
If it does not detect an audio signal for more than
approximately one minute, the transmitter will
stop sending  RF signals.
But the Power indicator remains lighting.  When
the transmitter receives an audio signal again, it
starts sending the RF signals.
If the audio signal is very weak, the transmitter
does not send RF signals automatically. In this
case, make sure the volume of the equipments
connected is set to 5 – 6.
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.

Note

If the transmitter is connected to the headphones jack of
the source equipment, set the volume of that equipment
as high as possible without distorting the audio signal.

Auto power on/off function

When you remove the headphones, the power
turns off automatically.  Do not allow the self
adjusting band to be pulled up, otherwise the
headphones will be switched on.

Mute function

If a hissing noise is heard when the headphones
are used outside of the effective range (see the
next section), the mute function will be activated
and the sound will not be heard from the
headphones.  To restore the sound, move near
toward the transmitter.

The power turns on.

The power turns off.
