This machine is a Shortwave Diathermy (SWD) - 500 W unit, a therapeutic device used in physiotherapy to deliver deep heat to body tissues using high-frequency electromagnetic energy. 

Key Specifications

Power Output: 500 Watts (Continuous mode), typically used for heavy-duty clinical or hospital applications.

Operating Frequency: Standardized at 27.12 MHz with a wavelength of approximately 11 meters.

Therapy Modes: Most 500W models offer Continuous mode for deep thermal effects in chronic conditions and Pulsed mode for acute
injuries to minimize heat buildup.

Timer: Generally features a digital timer programmable from 1 to 99 minutes, with automatic cut-off and an acoustic signal. 

Control Panel Explanation

Based on the visual layout of your machine, the controls typically function as follows:

Volt Selector: Adjusts the input voltage in steps to ensure the machine operates stably.

Tuning Knob: Manually adjusts the radio frequency to achieve maximum resonance and output for the specific patient's body part.

Intensity Knob: Controls the amount of heat energy delivered to the patient, often adjustable in steps (e.g., 1–5).

Mains Switch: The primary power toggle for the unit.

Meters: The left meter usually displays Voltage, while the right meter shows Output Intensity (mA). 

Therapeutic Uses

SWD is used to treat deep-seated musculoskeletal conditions, including:

Joint & Muscle Pain: Effective for osteoarthritis, rheumatoid arthritis, and chronic back or neck pain.

Injuries: Helps with ligament sprains, muscle strains, and frozen shoulder.

Healing: Promotes blood circulation, reduces inflammation, and relaxes muscle
