Inserting the batteries

q Remove the rear lid in the w Load the two batteries properly
direction of the arrow and as indicated by the marks in the
remove it. battery compartment.
e Put the rear cover back on.
NOTE
• Insert the specified batteries in the remote control unit.
• Replace the batteries with new ones if the set does not operate
even when the remote control unit is operated close to the unit. (The
supplied batteries are only for verifying operation. Replace them
with new batteries at an early date.)
• When inserting the batteries, be sure to do so in the proper direction,
following the q and w marks in the battery compartment.
• To prevent damage or leakage of battery fluid:
• Do not use a new battery together with an old one.
• Do not use two different types of batteries.
• Do not attempt to charge dry batteries.
• Do not short-circuit, disassemble, heat or dispose of batteries in
flames.
• Do not keep the battery in a place exposed to direct sunlight or in
places with extremely high temperatures, such as near a heater.
• If the battery fluid should leak, carefully wipe the fluid off the inside
of the battery compartment and insert new batteries.
• Remove the batteries from the remote control unit if it will not be in
use for long periods.
• Used batteries should be disposed of in accordance with the local
regulations regarding battery disposal.
• The remote control unit may function improperly if rechargeable
batteries are used.

Operating range of the remote control unit

Point the remote control unit at the remote sensor when operating it.
R03/AAA
Approx. 8 m
NOTE
• The set may function improperly or the remote control unit may not
operate if the remote control sensor is exposed to direct sunlight,
strong artificial light from an inverter type fluorescent lamp or
infrared light.
• When using 3D video devices that transmit radio communication
signals (such as infrared signals etc) between the various units (such
as the monitor, 3D glasses, 3D transmitter unit etc), the remote
control unit may not operate due to interference from those radio
communication signals. If this occurs, adjust the direction and
distance of the 3D communication for each unit, and check that the
remote control unit operation is not affected by these signals.

Explanation terms

B
Bi-wiring connection (PMA-720AE only)
This method of connecting a speaker by using two speaker cables
enables separate transmission of treble and bass signals.
This enables playback with minimal interference between the high-
range speaker unit and the low-range speaker unit.
P
Protection circuit
This is a function to prevent damage to components within the power
supply when an abnormality such as an overload or excess voltage
occurs for any reason.
In this unit, the power indicator blinks and the unit enters standby
mode when an abnormality occurs.
S
Source direct
Playback with higher fidelity to the source becomes possible, as input
audio signals are output by bypassing the audio quality-control circuits
(bass/treble/balance).
Speaker impedance
This is certain-rated resistance of the speaker set to an alternating
current and expressed in ohms.
The smaller the impedance, the greater the output. However, load
on the amplifier is increased. Use speakers whose impedance is
supported by this unit.
