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)
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.
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
TUNER
To set the AM tuning interval, while holding down the [TUNER] button, press the [MEMORY] button.
FM MODE
MEMORY
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.
CLEAR
Note: All presets are deleted when you change this setting.

B STANDBY/ON button (24) 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 momentary 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. 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.
