the left housing of the headphones to
open the battery compartment, then
remove the lid.

When to change the batteries
The operation indicator b on the right housing of the
headphones lights in red when the [OPR] switch a on
the left housing of the headphones is turned "ON". When
the batteries become weak, the indicator dims or fails to
light. Noise and interference also increase. Change the
batteries if any of the above occurs.
Installation
This unit uses an infrared beam. The approximate area
in which the infrared beam from the transmitter (beam
emitter c) can reach the headphones (beam sensor d)
is shown in the fi gure. Install the infrared beam transmitter
within the area indicated.
e: Approx. 3 m
f: Approx. 8 m
Note
● As infrared beams can not pass through walls or
window panes, the headphones must be used where
the infrared beam transmitter is directly visible without
any obstructions.
● Do not expose the headphones to direct sunlight or to
the bright light of an inverter fl uorescent light.
