When pacemakers are installed, most doctors warn patients to stay away from electric, magnetic field (EMF), and high fre-quency (RF) sources. However, EMF and RF are invisible and today
For AC Electrical fields, alarm threshold is 4 KV/m., calibrated at 60 Hz. Frequency range is from 30 Hz to 5 KHz.
For RF, 500 KHz to 5.5 GHz, alarm threshold is 100 V/m (2.65 mW/cm2), calibrated at 2.45 GHz.
For Magnetic fields, alarm threshold is 1.5 Gauss, calibrated at 60 Hz. Frequency range is from 30 Hz to 5 KHz.
Unit is powered by a 9V battery. Current drain is about 30mA without alarm.
