Are two-way pagers and PDAs safe to use?

Two-way pagers and PDAs are safe to use as long as they are kept sufficiently far away from an ICD. How far? It depends on the power transmission level of the radio you're using. Follow these minimum distances to avoid interference with your ICD:   3 watts or less = 6 inches (15 cm) 3-15 watts = 12 inches (30 cm) 15-30 watts = 24 inches (60cm) 30-50 watts = 3 feet (1 meter) 50 - 125 watts = 6 feet (2 meters)   Over and out.
