3. Setup and Assembly
Before first use, ensure all components are present and in good condition. The kit is largely pre-assembled, but a few steps may be necessary.
- Unpack Components: Carefully remove the sphygmomanometer, stethoscope, and carrying case from their packaging.
- Inspect Stethoscope Eartips: Ensure the Adsoft Plus silicone eartips are securely attached to the binaurals. Replace if damaged or missing using the provided spares.
- Connect Cuff and Manometer: The Adcuff is typically pre-connected to the manometer. Verify the tubing is securely attached to both the cuff and the manometer's air release valve.
- Familiarize Yourself with the Carrying Case: The oversized nylon carrying case is designed for convenient storage and transport of your kit.
4. Operating Instructions
4.1. Using the Prosphyg 778 Sphygmomanometer
The Prosphyg 778 is designed for accurate blood pressure measurement.
- Cuff Placement: Select the appropriate Adult nylon Adcuff. The cuff features a Size Guide marking system to ensure correct placement and prevent miscuffing. Position the cuff on the patient's arm, ensuring the artery marker aligns with the brachial artery. The cuff should fit limbs from 9" to 15.7" (23-40 cm).
- Inflation: Close the Adflow chrome-plated brass air release valve by turning it clockwise. Inflate the cuff by squeezing the bulb until the manometer reads approximately 20-30 mmHg above the expected systolic pressure.
- Deflation: Slowly open the air release valve by turning it counter-clockwise. The micro-threads allow for precise deflation control, typically at a rate of 2-3 mmHg per second.
- Reading: Observe the manometer dial as the pressure decreases. Note the systolic pressure (first sound) and diastolic pressure (last sound) using your stethoscope.

4.2. Using the Adscope 603 Stethoscope
The Adscope 603 is designed for clear auscultation of body sounds.
- Eartip Insertion: Gently insert the Adsoft Plus silicone eartips into your ears, ensuring a comfortable and secure fit. The eartips are designed for an acoustic seal.
- Chestpiece Selection: The Adscope 603 features a combination diaphragm/bell chestpiece. Rotate the chestpiece to select either the diaphragm or the bell. The diaphragm is ideal for higher frequency sounds, while the extra-large bell provides an unsurpassed low-frequency response.
- Auscultation: Place the selected side of the chestpiece firmly on the patient's skin over the area to be auscultated (e.g., heart, lungs, arteries). Listen carefully for the desired sounds.
5. Care and Maintenance
Proper care ensures the longevity and accuracy of your ADC diagnostic kit.
- Cleaning the Cuff: The Adcuff is reusable. Clean the cuff regularly with a mild disinfectant solution and allow it to air dry completely. Do not immerse the manometer in liquid.
- Cleaning the Stethoscope: Wipe the stethoscope tubing, chestpiece, and binaurals with an alcohol wipe or mild disinfectant. Remove eartips for thorough cleaning if necessary.
- Manometer Care: The Adflow filter screen check and deflation valves help reduce dust build-up. Keep the manometer clean and free from debris.
- Storage: Store all components in the provided oversized carrying case when not in use. This protects the instruments from damage and dust.

6. Troubleshooting
If you encounter issues with your ADC Pro's Combo III kit, consider the following common solutions:
- Inaccurate Blood Pressure Readings:
- Ensure the correct cuff size is used and properly positioned on the arm.
- Check for leaks in the cuff or tubing.
- Verify the air release valve is functioning correctly.
- Poor Stethoscope Sound Quality:
- Confirm eartips are securely attached and form a tight seal in your ears.
- Ensure the chestpiece is rotated to the desired side (diaphragm or bell) and is firmly against the skin.
- Check for blockages in the tubing or chestpiece.
- Manometer Not Holding Pressure:
- Tighten all connections between the cuff, tubing, and manometer.
- Inspect the cuff and tubing for any punctures or damage.
- Ensure the air release valve is fully closed before inflation.
If problems persist, refer to the warranty and support section for further assistance.
