Before using this unit
Plug the supplied power cord into this AC INLET.
• Do not use a power cord other than the one supplied with the
DTR-6.4/5.4. The power cord supplied is designed for use with
the DTR-6.4/5.4 and should not be used with any other device.
• Never have the power cord disconnected from the DTR-6.4/5.4
while the other end is plugged into the wall outlet. Doing so
may cause an electric shock. Always connect by plugging into
the wall outlet last and disconnect by unplugging from the wall
outlet first.
Note:
The shape of the power cord plug will be different depending on the
shipping area.
1. Remove the battery compartment cover by pressing it
and sliding it in the direction shown by the arrow below.
2. Insert two AA (or R6) batteries into the battery
compartment. Carefully follow the polarity diagram
(positive and negative symbols) inside the
battery compartment.
3. After the batteries are installed and seated correctly,
replace the compartment cover.
Notes:
• Do not mix new batteries with old batteries or different kinds of
batteries.
• To avoid corrosion, remove the batteries if the remote controller
will not be used for a long time.
• Remove dead batteries immediately to avoid damage from corrosion.
If the remote controller does not operate smoothly, remove the old
batteries and replace them both with two new AA batteries.

Point the remote controller toward the remote control sensor. The
Standby indicator lights up when the unit receives a signal from the
remote controller.
Notes:
• Make sure that the remote control sensor is not subject to strong
light such as direct sunlight or inverted fluorescent light for it
may prevent proper operation of the remote controller.
• Using another remote controller in the same room or using the
DTR-6.4/5.4 near equipment that uses infrared rays may cause
operational interference.
• Do not put objects on the remote controller. Its buttons may be
pressed by mistake and drain the batteries.
• Make sure the audio rack doors do not have colored glass.
Placing the DTR-6.4/5.4 behind such doors may prevent proper
remote controller operation.
• If there is any obstacle between the remote controller and the
remote control sensor, the remote controller will not operate.
