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.

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

(Worldwide models only)

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 compati­bility with AM broadcasts in your particular country. The ini­tial setting is 9 kHz.

North America: 10 kHz
Other countries: 9 kHz

T o set the AM tuning interval, while
holding down the [TUNER] button,
press the [MEMORY] button.

E FRONT SPEAKERS A, SURROUND SPEAKERS,

CENTER SPEAKER & SURROUND BACK
SPEAKER (21)

These terminal posts are for connecting speaker set A, includ­ing the front, surround, center, and surround-back speakers.
They accept bare wires or banana plugs (European models
don’t accept banana plugs).

F AC OUTLET (11)

This switched AC outlet can be used to supply power to
another AV component. The connector type depends on the
country in which you purchased your TX-SR501/
TX-SR501E.

G DIGITAL INPUT OPTICAL 1, 2 & COAXIAL (10,

13, 14, 16–18)

CD, DVD, or LD (laser disc) player, or other AV component
with digital outputs.

This (Remote Interactive) connector can be connected to
the connector on another Onkyo AV component, for
example, a CD player, DVD player, or cassette recorder. The
TX-SR501/TX-SR501E’s remote controller can then be used
to control that component. To use , you must make an ana­log RCA/phono connection between your TX-SR501/
TX-SR501E and the other AV component, even if they are
connected digitally.

L VIDEO 1 IN/OUT & VIDEO 2 IN (10, 14–16, 39)

Tip:

A turntable with a built-in preamp can be connected to a pair of
unused TX-SR501/TX-SR501E analog inputs. To connect a
turntable without a built-in preamp, you’ll need a commer­cially available phono preamp. See pages 17 and 18 and the
instructions supplied with your phono preamp and turntable for
more information.
