Topside this is Mark go ahead When transmitting speak slowly and in one continuous sentence Try not to make long sentences It is always a good idea to have the divers repeat the mes sage back so you know they clearly understood your message Remember that listening to divers is usually easier than divers listening to the topside tender It is important that the transducer be protected It is designed using a material that can break if sharply hit or impacted Do not hang the transducer in a position that is blocked and do not lay it on the sea bottom Inform the divers that if they go below a thermocline they should inform ev eryone If possible lower the transducer to the same depth as the divers in the thermocline If you are using the SP 100D on a vessel always remember to pull up the trans ducer when moving the vessel Many transducers have been lost when cut off by a propeller Keep the hand held microphone as dry as possible It is not waterproof Place the SP 100D where it can be heard easily If working on a boat locate a place where you can secure the unit where boat action will not cause it to fall Also remember to dress the transducer cable in such a way that divers and or topside personnel will not trip over it If this is the first time you or any other member of your team is using commu nications we recommend that your team get together to talk about the system Plan alternative communications in th
