900 SERI ES™ INTRODUCTION Y our 900 Series™ Ultra Wide Screen Fishing System comes in several dif ferent configurations. See the following list of pr oducts, all of which ar e cover ed by this manual, to find your 900 Series™ configuration: NO TE: Only the 987c SI Combo model comes with GPS and built -in cartography .
2 GPS AN D CART OGRAPHY (With 987c SI Combo models only) Y our 987c SI Combo model uses GPS and sonar to determine your position, display it on a grid, and provide detailed underwater inf ormation. The Global Positioning System (GPS) is a sat ellite navigation syst em designed and maintained by the U.
Use the illustration to locate the position of the MM C and SD slot cover , remove the cover , and then inser t an MMC and/ or an SD card into one or both slots - either slot can accept either an MMC or an SD card. The label on both types of cards should face down and away from y ou so that you’re looking at the back of the card.
4 Inside the boat there is often a c hannel or conduit used for other wiring , this can be used to rout e cables. Be sure to r oute the cable as far as practical from the antenna cable of VHF radios or tachometer cables to r educe the possibility of interference.
GIMBAL MOUNTING TH E C ONTROL HEAD If you are gimbal mounting the Humminbird® 900 Series™, you can pre-assemble the unit in order to plan the best mounting location.
6 5. Set the gimbal brack et aside and drill the four mounting screw holes using a 5 /32" (4.0 mm) drill bit. 6a. If the cables must pass through a hole directly beneath the mounting brac ket, mark and drill an additional 1" (25 mm) hole centered between the f our mounting holes.
8. Insert cable connectors into the pr oper recesses on the cable collector insert. The cable connectors are k eyed to prevent reverse installation, so be careful not to force the c onnectors int o the wrong slots. If you don ’t have a cable for ever y hole in the insert, install the blank plugs to protect the con trol head from the weather .
8 9 . While holding cables in place in the cable collector insert, thread the cables through the slot in the bot tom of the cable c ollector cover , line up the cable collector insert and cover , then slide the cover into place on the insert. NO TE: T ab on cable collector insert goes into slot on cover .
5. Inser t the contr ol head through the mounting hole from the fron t side of the dash. From the bac k side of the dash, align the two threaded rods on the rear of the housing with the two holes on the in- dash mounting bracket.
10 C ONN ECTING TH E C ONTROL H EAD POWER CABLE T O THE BOA T A 6' (2 m) long power cable is included to supply power to the c ontrol head. Y ou may shorten or lengthen the cable using 18 gauge multi- stranded copper wire.
TRANSDUCER I NS T ALLA TION There are two dif feren t installation methods for your transducer: • T ransom T ransducer • T rolling Motor T ransducer .
12 NO TE: Rough seas also can aff ec t the readings of the Side Imaging transducer . NO TE: The transducer must be mounted at least 15” from the pr opeller to avoid interference from the motor .
1. First, determine the best location on the transom to install the transducer . Consider the f ollowing to find the best location: • It is very important to locate the transducer in an area whic h is relatively free of turbulent water .
14 5. Align the metal moun ting brack et with the mounting holes. The center slot should be above the two out er slots. (This brack et and all other hardware supplied is top quality stainless steel for maximum strength and corrosion pr otection.
T o adjust the running position of the transducer: The transducer mounting brack et allows height and tilt adjustment, while the pivot bolt allows angular adjustment. These adjustments will help reduce cavitation. Initially , adjust the transducer as described in the following paragraphs.
16 2. If you will be routing the cable through a hole in the transom, drill a 5 /8" diameter (16 mm) hole above the waterline. Rout e the cable through this hole, then fill the hole with marine- grade silicone sealant and proceed t o the next step immediately .
TES T AN D FIN ISH THE TRANSDUCER I NS T ALLA TION When you have installed both the contr ol head, the transducer , and accessories and have routed all the cables , you must per form a final test bef ore locking the transducer in place.
18 GPS RECE IVER INST ALLA TION (987c SI Combo models only) NO TE: Y ou will only need to perform this procedure if you have a GPS R eceiver . T o optimize per formance of the GPS receiver , mount it in an area that has full e xposure to the sky . The effective area of reception is 10 ° above the horizon.
AC CESS U NDER MOU NTING LOCA TION Follow these steps t o deck mount the GPS r eceiver when routing the cable down through the mounting location: 1. Determine the best location, then test r oute the 20' (6 m) cable from the mounting location to the c ontrol head.
20 FIN ISH ROUTING TH E CABLE AND CH ECK GPS RECE IVER OPERA TION Af ter installing a GPS receiver , you should perform the following procedure t o finish routing the GPS cable to the c ontrol head and to chec k to make sure that the c ontrol head is working correctly .
The Speed accessory incorporates a paddlewheel-type speed sensor in a high-impact plastic housing. The module is intended for installation on the transom, and will work well on almost any boat. In addition to the parts supplied, you will need a hand drill with various bits, marine- grade silicone sealant, and a Phillips head scr ewdriver .
22 2. Clean the paddlewheel by disengaging the axial clip from the housing wedge and rotating it forward. Once you have rotat ed the axial clip, remove it fr om the housing by sliding it away from the holes in the housing. 3. Clean the removed paddlewheel with a mild solution of biodegradable soap or hot water .
GETTING ST ARTED - USI NG Y OU R 900 SERIES™ Y our 900 Series™ Fishing System user interface is easy to use. A c ombination of keys, diff erent views , and situation- specific, customizable menus allows you to con trol what you see on the color display .
24 WHA T ’S ON TH E SONAR DISPLA Y The 900 Series™ can display a variety of useful information about the area under and adjacen t to your boat, including the following it ems: Sonar Color Bar - color spectrum indicating low to high sonar intensity returns, where red indicates high intensity and white indicat es low intensity .
UN DERS T ANDI NG SONAR HIST ORY It is important to understand the significance of the 900 Series™ display . The display does NO T show a literal 3- dimensional representation of what is under the water .
26 WhiteLine® highlights the strongest sonar r eturns in white, resulting in a distinctive outline. This has the benefit of clearly defining the bot tom on the display . UN DERS T ANDI NG SIDE I MA GI NG It is important to understand how Side Imaging technology produces the display available on the 900 Series™.
WHA T ’S ON TH E SIDE IMAGING DISPLA Y Side Imaging displays a number of easily recognizable f eatures that allow for accurat e interpretation of bot tom con tour and str ucture. For Side Imaging, the bottom c omposition determines the intensity of the sonar r eturn.
28 SIDE IMAGING TECH NOLOGY: HO W IT WORKS Side Imaging sonar uses two very precise sonar beams that are directed to either side of the boat and “illuminate ” the bottom c ontour , structure, and fish, and display results in a “picture-like ” image.
