2. To initialize the unit
This device employs a microprocessor to perform various
functions and operations. If interference generated by an external
power supply, radio wave, or other electrical source results in
accident which causes the specified operations and functions to
operate abnormally.
To perform a result, please follow the procedure below.
1.Press and hold down the VIDEO-1 button, then press the
STANDBY/ON button.
2.After "CLEAR" is displayed, the preset memory and each
mode stored in the memory, such as surround, are
initialized and will return to the factory setting.
3. Unplug the power supply cord.
3. Safety-check out
(U.S.A. model only)
After correcting the original service problem, perform the
following safety check before releasing the set to the customer.
Leakage Current Check
Measure leakage current to a known earth ground(water pipe,
conduit, etc.) by connecting a leakage current tester between
the earth ground and exposed metal parts of the appliance
(input/output terminals, screwheads,metal overlays, etc.).
Plug the power supply cord directly into a 120V AC 60 Hz outlet
and turn Standby switch on. Any current meausred must not
exceed 0.5mA.
1. Replacing the fuses
This symbol located near the fuses indicates that the
fuse used is fast operating type. For continued protection against
fire hazard, replace with same type fuse. For fuse rating refer to
the marking adjacent to the symbol.
Ce symbole indique que le fusible utlise est a rapide.
Pour une protection permanente, n'untiliser que fusibles de
meme type. Ce darnier est la qu le present symbol est
appse.
4.Setting the voltage selector (Worldwide models
only)
Worldwide models are equipped with a voltage selector to conform
with local power supplies. Be sure to set this switch to match the
voltage of the power supply in your area before plugging in the unit.
Determine the proper voltage for your area: 220-230 V or 120 V. If
the preset voltage is not correct for your area, insert a screwdriver
into the groove in the switch. Slide the switch all the way to the
upper (120 V) or to the lower (220-230 V), whichever is appropriate.
5.Setting the AM tuning step frequency

If you are using the Worldwide model (i.e., your TX-SR501/
TX-SR501E has a VOLTAGE SELECTOR on the rear
panel), you need to set the AM tuning interval for compati-
bility with AM broadcasts in your particular country. The ini-
tial setting is 9 kHz.
North America: 10 kHz
Other countries: 9 kHz
Note:
All presets are deleted when you change this setting.
To set the AM tuning interval, while
holding down the [TUNER] button,
press the [MEMORY] button.

Controls & Connectors--Continued
Rear Panel
A COMPONENT VIDEO (10, 12, 14, 16)
These RCA/phono connectors can be used to connect a TV,
DVD player, or other AV component with component video
inputs and outputs.
B AM ANTENNA (22, 23)
These push terminals are for connecting an AM antenna.
C FM ANTENNA (22, 23)

cially available phono preamp. See pages 17 and 18 and the
instructions supplied with your phono preamp and turntable for
more information.

Front Panel
A POWER switch (24)
The North American model doesn't have this switch.
This is the main power switch. When set to OFF, the
TX-SR501/TX-SR501E is completely shutdown. When set to
ON, the TX-SR501/TX-SR501E is in Standby mode and the
STANDBY indicator lights up.
Don't turn on the power until you've completed, and double
checked all connections.
Note:
Turning on the TX-SR501/TX-SR501E may cause a momen-
tary power surge that might interfere with other electrical
equipment on the same circuit. If this is a problem, plug the
TX-SR501/TX-SR501E into a different branch circuit.
B STANDBY/ON button (24)
This button is used to set the TX-SR501/TX-SR501E to On or
Standby. For models with a POWER switch, this button has no
effect unless the POWER switch is set to ON.
C STANDBY indicator (24)
This indicator lights up when the TX-SR501/TX-SR501E is in
Standby mode, and it flashes while a signal is being received
from the remote controller.
D DIMMER button (32)
This button is used to adjust the display brightness.
E DIGITAL INPUT button (24)
This button is used to assign the digital inputs.
F SUBWOOFER MODE button (25)
