Repair of Spot Vital Signs 42MTB Monitor

The Welch Allyn Spot Vital Signs 420TB is a portable vital-signs monitor used for screening and episodic monitoring in clinical settings. The unit displays blood pressure, heart rate, temperature, and pulse oximetry on a handheld display. It is commonly deployed in urgent care, primary care, and occupational health environments where rapid vital-sign acquisition is needed without integration to a central station.
