The sealed electronic ringer also prevents contaminants from entering the housing. This telephone is provided with a noise-canceling microphone. The stainless steel handset cord remains flexible in the most extreme temperatures. Our crane communication system is ideal for locations where communication through any means is not possible, either because of impossible cabling or position in giant & high cranes.
