OTS / Lifeguard ® Install Tutorial © 2015 Cochran Consulting, Inc. The Cochran Lifeguard CPU Dive Computers transmits a signal to the Lifeguard D1 to display dive data. The Lifeguard D1 is used by the diver to see the dive data and the Lifeguard D1 is also used to see this same data remotely at the surface. The remote Lifeguard D1 receives this signal using the Audio Communication Line. A Lifeguard Pickup is placed near the Lifeguard CPU Module and is inserted between the Audio Communication Line and the diver’s mask to transmit this signal. A Lifeguard Antenna Adaptor is inserted between the OTS Buddy Line and the Audio Communication Line. The Lifeguard D1 is connected to this adaptor to receive the signal from the Lifeguard CPU Module. The Pickup is passive and requires no batteries. IMPORTANT: Always keep the Pickup terminated. This means it should be connected in a system or the two connectors on the Pickup should be connected to each other. Introduction
