The Signal Communications User-Powered Call Box operates simply and efficiently. Pull the handle, push the desired button(s) "Police”, "Ambulance”, "Service”, etc., release the handle and the energy stored in the mechanical module provides power to the radio transmitter. In approximately 1/2 a second the dispatch center will receive the transmission. Upon receipt of the transmission, a verification signal is returned to the activated Call Box, alerting the user that assistance is on the way.
