Introduction
The GAI-Tronics RF Call Boxes are designed for isolated areas requiring voice communication 
equipment, using wireless RF technology to provide half-duplex communication. These units are ideal 
for areas where underground or overhead cabling is undesirable or not available. The simple push-to-
talk, release-to-listen operation provides user-friendly functionality, and these designs are extremely 
resistant to vandalism.
