SECTION 2 SETUP AND OPERATION SETUP 1. Set the DRS-100 Diver Recall/Hydrophone System on a flat surface where you will use it, with the carrying handle facing the user. 2. Open the housing by pulling up on the clamps located on either side of the carrying handle, and raise the lid. -
Page 9: Tone/Recall Mode
If your sound source has no DC path to ground (DRS-100 chassis ground) via the output circuit of your device, you may need an adapter (OTS p/n 914024-000). Additionally, be careful not to allow salts, water, minerals, etc. to build up around this jack, because they could cause the transmitter to activate due to electrical conduction at the jack. -
