The main station is located in the control room, and remote stations are located throughout the studio and production areas. The remote stations used most often are belt packs that are worn by the crew member. To this is attached a headset that includes either one or two earphones and a mic for talkback.
Operation is fairly simple.
For studio personnel other than camera operators, the intercom jacks are located on the large silver panel on the studio wall. Camera operators may connect their belt pack to the intercom jack on the right rear side of the camera body. Attach a headset to the belt pack. Adjust the volume control to your personal preference. To talk, press and hold the talk button, or press twice quickly to latch in the on position.
