2. Safety Precautions

Always observe the following safety guidelines to prevent electric shock, fire, or damage to the unit and connected appliances.

• Do not exceed the maximum power rating of 500W.
• Ensure the input voltage selector on the back of the unit matches your local power supply before connecting.
• Use in a well-ventilated area. Do not cover ventilation openings.
• Keep away from water, moisture, and high temperatures.
• Do not open the casing. Refer all servicing to qualified personnel.
• Unplug the unit from the power source when not in use.

3. Setup

Follow these steps to set up your transformer:

1. Unpack the Unit: Carefully remove the transformer from its packaging. Inspect for any signs of damage.
2. Choose a Location: Place the transformer on a stable, flat surface in a dry, well-ventilated area, away from direct sunlight and heat sources. Ensure there is adequate space around the unit for air circulation.
3. Select Input Voltage: Locate the input voltage selector switch on the rear panel of the transformer.

   Set the switch to match your local power supply voltage (e.g., 110V for North America, 220V for Europe/Asia). Incorrect voltage selection can damage the unit and connected appliances.

4. Connect to Power Source: Plug the transformer's power cord into a grounded wall outlet. The "POWER SOURCE" indicator light on the front panel should illuminate.

4. Operating Instructions

To operate the ST-500 transformer:

1. Power On: Ensure the transformer is plugged into the wall outlet and the input voltage is correctly selected. Flip the red "POWER ON/OFF" switch to the "ON" position. The "POWER SOURCE" indicator light should be green.
2. Connect Appliance:
   • If your appliance requires 110V output, plug it into the "OUTPUT 110V" socket.
   • If your appliance requires 220V output, plug it into the "OUTPUT 220V" socket.

   Always ensure the appliance's power consumption does not exceed the transformer's 500W capacity.

3. Use Appliance: Turn on your connected appliance. The transformer will convert the voltage as required.
4. Power Off: When finished, turn off your appliance first, then flip the transformer's "POWER ON/OFF" switch to "OFF". Unplug the appliance from the transformer, and then unplug the transformer from the wall outlet.

5. Maintenance

Proper maintenance ensures the longevity and safe operation of your transformer.

• Cleaning: Disconnect the transformer from all power sources before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use liquid cleaners or solvents.
• Ventilation: Regularly check that the ventilation grilles are free from dust and obstructions.
