INSTALLATION & OPERATIONSIMULCOM - WHAT WHY and HOW (continued) 6.12TO OPERATE AND/OR CHECK-OUT SIMULCOM1. Attach hat to umbilical.2. Attach comm-cable to AMCOM III, red banana plug to Diver 1 microphone, black bananaplug to Diver 1 earphone.3. Don hat and talk to yourself; if you hear your voice over the earphones the system isworking.To revert back to 2-wire, remove black banana plug from earphone jacks (AMCOM III) and pluginto top of microphone banana plug (red).TO RECAP - We now have a system where diver 1’s microphone is connected to the Diver 1microphone input of the AMCOM III and Diver 1’s earphone is connected to the earphone for Diver1. All features such as diver push to talk switch and independent volume controls of the AMCOMIII remain intact. Tender uses a headset, which is plugged into the tender microphone and headsetjacks.With the AMCOM III system you can mix 2-wire/simulcom systems, for example, Diver 1 and 2could be Simulcom while Tender can be 2-wire (no headset - use speaker for tender). Or, onediver can be 2-wire and one can be Simulcom. Just remember if any one person is on two-wireyou must use the push to talk (PTT) for that diver to hear or for the tender to talk.Note: the PTT switch overrides diver conversations, (see operating guide for details).Other configurations, which can be implemented with Simulcom systems:1. Remote station for equipment operator, or second tender on 2-wire or Simulcom.2. Several remote stations with any combination of 2-wire or Simulcom.27
