POWER LINE SIZES RECOMMENDED FOR AQUA PROBE DIGITALS LENGTH OF WIRE PAIR MINIMUM SIZE* up to 20' #16 AWG 20' to 30' #14 AWG 30' to 40' #12 AWG over 40' #10 AWG * - refer to USCG wiring requirements. TRANSDUCER CONNECTION FOR NO. 530 and 550 DEPTHFINDERS: The transducer connectors on the No. 530 and No. 550 Aqua Probe digital depthfinders are special HEAVY GOLDPLATED, MIL-SPEC VERSIONS of the industry- standard universal RCA type phono connectors. These connectors are provided both on the transducer cable and the unit itself. The connection is simply made by inserting the plug on the cable into the socket on the back of the depthfinder. Use a slight, clockwise twisting motion, until the connectors are seated properly. Disconnection is accomplished with a similar clockwise, twist/pull action. WARNING: NEVER ATTEMPT TO REMOVE THE PLUG BY PULLING ON THE CABLE! Always use the knurled hold-area of the connector as a grip in disconnecting the transducer. Additional transducer-installation information is provided with the transducer. Each of the transducer types- transom mount, thru hull, or puck-type-has its own installation requirements. TRANSDUCER CONNECTION FOR THE NO. 540 REMOTE The No. 540 digital remote indicator is completely self- contained. No modification to your existing depthfinder head is necessary. All you have to do is plug the transducer cable into the No 540 remote, plug the No. 540 remote's jumper cable into the transducer socket on your depthfinder, and provide a 12V-DC, negative ground power connection. The accuracy and sensitivity of your depthfinder will not be affected. The No. 540 remote depth indicator connects directly to any Aqua Meter or other popular depthfinder in the 175 to 225 KHz range. The only connection between your new Aqua Probe No. 540 digital remote depth indicator and its master "main" depthfinder is the Jumper Cable which is supplied with the unit. If the main unit is a flasher or graph depthfinder, you may want to install your new No. 540 digital nearby. Assuming the main depthfinder's transducer connector is a standard, RCA phono type of plug, simply plug the main depthfinder's transducer directly into the appropriate, transducer 7
