Face the source (for example, your TV) and switch the
HEAD TRACKING switch to ON. Wait for 2 seconds
without moving.
Do not move your head until the head tracking system

After the head tracking system stabilizes, playback
sound can be heard. After this, even if you turn your
head in any direction, the sound will be heard as if
from the front.
Notes
• Always wear the headphones vertically so that
the head tracking system will be stable.
• Whenever the HEAD TRACKING switch is set
to ON, and whenever you put on the
headphones with its power on, always wait for 2
seconds without moving your head as the head
tracking system newly stabilizes each time.
• If the sound from the headphones (while facing
your TV) seems to be different from the
actual direction of your TV, face forwards and
press the RESET button on the headphones.
The headphones automatically turn off
when they are taken off

power.
To check the remaining battery power
Pull up the self-adjusting band and check the POWER
indicator. The batteries are still serviceable when the
POWER indicator lights red.
Charge the rechargeable batteries or use new alkaline
batteries if the POWER indicator flashes and an
intermittent beep sound is heard from the
headphones.
If no sound is heard from the headphones
A short beep sound is heard repeatedly and the
Muting Function is automatically activated if the
sound output from the headphones is cut off when the
headphones are outside the infrared transmission
area, or when the infrared signals are interrupted. The
Muting Function is automatically cancelled when you
get closer to the processor or there is no longer
anything in the way of the infrared signals.
