Inserting batteries into the remote Insert two R6 (size-AA) batteries in the RM-AAU021 Remote Commander. Observe the correct polarity when installing batteries. Notes • Do not leave the remote in an extremely hot or humid place. • Do not use a new battery with old ones. • Do not mix manganese batteries and other kinds of batteries. • Do not expose the remote sensor to direct sunlight or lighting apparatuses. Doing so may cause a malfunction. • If you do not intend to use the remote for an extended period of time, remove the batteries to avoid possible damage from battery leakage and corrosion. • When you replace the batteries, the remote buttons may be reset to their factory settings. If this happens, reassign the buttons again (page 76). Tip Under normal conditions, the batteries should last for about 3 months. When the remote no longer operates the receiver, replace all the batteries with new ones. 7: Calibrating the appropriate settings automatically (AUTO CALIBRATION) The DCAC (Digital Cinema Auto Calibration) function allows you to perform automatic calibration such as: • Checking the connection between each speaker and the receiver. • Adjusting the speaker level. • Measuring the distance of each speaker from your listening position. The DCAC is designed to obtain proper sound balance in your room. However, you can adjust the speaker levels and balance manually according to your preference. For details, see "8: Adjusting the speaker levels and balance (TEST TONE)" (page 33). Before you perform Auto Calibration Before you perform Auto Calibration, install and connect the speakers (page 14, 16). • The AUTO CAL MIC jack is used for the supplied optimizer microphone only. Do not connect other microphones to this jack. Doing so may damage the receiver and the microphone. • During calibration, the sound that comes out of the speakers is very loud. The volume of the sound cannot be adjusted. Pay attention to the presence of children or to the effect on your neighborhood. • Perform Auto Calibration in a quiet environment to avoid the effect of noise and to get a more accurate measurement. • If there are any obstacles in the path between the optimizer microphone and the speakers, the calibration cannot be performed correctly. Remove any obstacles from the measurement area to avoid measurement error. continued 29US Getting Started

Getting Started
Insert two R6 (size-AA) batteries in the
RM-AAU021 Remote Commander.
Observe the correct polarity when installing
batteries.
Notes
• Do not leave the remote in an extremely hot or
humid place.
• Do not use a new battery with old ones.
• Do not mix manganese batteries and other kinds of
batteries.
• Do not expose the remote sensor to direct sunlight
or lighting apparatuses. Doing so may cause a
malfunction.
• If you do not intend to use the remote for an
extended period of time, remove the batteries to
avoid possible damage from battery leakage and
corrosion.
• When you replace the batteries, the remote buttons
may be reset to their factory settings. If this
happens, reassign the buttons again (page 76).
Tip
Under normal conditions, the batteries should last
for about 3 months. When the remote no longer
operates the receiver, replace all the batteries with
new ones.
7: Calibrating the
appropriate settings
automatically
(AUTO CALIBRATION)
The DCAC (Digital Cinema Auto Calibration)
function allows you to perform automatic
calibration such as:
•
Checking the connection between each
speaker and the receiver.
•
Adjusting the speaker level.
•
Measuring the distance of each speaker from
your listening position.
The DCAC is designed to obtain proper sound
balance in your room. However, you can
adjust the speaker levels and balance manually
according to your preference. For details, see
“8: Adjusting the speaker levels and balance
(TEST TONE)” (page 33).
Before you perform Auto Calibration, install
and connect the speakers (page 14, 16).
•
The AUTO CAL MIC jack is used for the
supplied optimizer microphone only. Do not
connect other microphones to this jack.
Doing so may damage the receiver and the
microphone.
•
During calibration, the sound that comes out
of the speakers is very loud. The volume of
the sound cannot be adjusted. Pay attention
to the presence of children or to the effect on
your neighborhood.
•
Perform Auto Calibration in a quiet
environment to avoid the effect of noise and
to get a more accurate measurement.
•
If there are any obstacles in the path between
the optimizer microphone and the speakers,
the calibration cannot be performed
correctly. Remove any obstacles from the
measurement area to avoid measurement
error.
