FOR A COMPLETE DESCRIPTION OF THE OPERATION OF THIS UNIT, PLEASE REFER
TO THE OPERATION MANUAL.
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chas-
sis and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,
cabinet,terminalboard,adjustmentandcompartmentcov-
ers or shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage
current in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the
resistor (See diagram).
* Connect the resistor connection to all exposed metal parts
havingareturnpathtothechassis(antenna,metalcabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.

Notes concerning use:
Replace the batteries if the operating distance is reduced
or if the operation becomes erratic.
Periodically clean the transmitter LED on the remote con-
trol and the sensor on the main unit with a soft cloth.
Exposing the sensor on the main unit to strong light may
interfere with operation. Change the lighting or the direc-
tion of the unit.
Keep the remote control away from moisture, excessive
heat, shock, and vibrations.

EXPLANATION OF AUTOMATIC SOUND VALUE CORRECTION CONTROL
1. Outline
The recent trend is toward rise of SOUND level in the world, for example rock, dancing music, etc. In case of continuous high
levelplaybackandVOL(Volume)arecontrolled(lowered)automaticallyafteralapse soastogettheeasy-to-listensoundlevel.
The ALC (Automatic Level Control) of the HT-DP4000 begins to operate immediately after the power is turned on.
2. Explanation of operation
The SOUND operation is explained below.

ALC operation
1 The ALC (Automatic Level Control) will begin operation immediately after the power switch is turned on.
2 If the sound exceeds level X , the ALC will instantaneously cut the volume back to level X , and it will also respond to
monophonic signals.
3 Since this control only effects the VOL level, it does not otherwise change the quality of the sound.

NOTES ON SCHEMATIC DIAGRAM
• Resistor:
To differentiate the units of resistors, such symbol as K and
M are used: the symbol K means 1000 ohm and the symbol
M means 1000 kohm and the resistor without any symbol is
ohm-type resistor. Besides, the one with “Fusible” is a fuse
type.
• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the
capacitorwithoutsuchasymbolismicrofarad.Astoelectro-
lytic capacitor, the expression “capacitance/withstand volt-
age” is used.
