The guard protected mode switch selects from either VOX ON and VOX OFF or VOX and Continuous Live Mic, depending on your network type. The Battery Condition Indicator Light completes the top mounted control group. Starting out bright red with fresh batteries, the light dims as the batteries are used up. PTT versions have the sealed, PTT button on the Belt-Pak's face, where it's easy to find and operate. The gasket sealed, thick walled polycarbonate case surrounds and protects the electronics.
Batteries fit neatly into a sealed compartment.
The receiving antenna is located inside the Belt-Pak. The six inch, trailwire transmitting antenna hangs straight down and out of your way. The stainless steel belt clip withstands the fifty pound pull test for fire ground equipment. Stainless steel hardware completes our material selection. The Series 4B Belt-Pak is tough and rugged.
