to move down the edge of the paper while the sound pulse is traveling through the water, and INTRODUCTION The Lowrance X-16 is a highly sophisticated recording depth sounder Thanks to a micro-computer, the X-16 can do more than any other sonar unit in its price range plus many that cost much more. Using the waterproof keyboard, full control of the systemis at your fingertips to meet the changing demandsof varying bottom conditions, water depth, and boat speed.

The red wire in the power cable is the positive conductor The black wire is the section for moreinformation on these wires. TRANSDUCER SELECTION Lowrance offers you the choice of transducers with either an 8 or 20 degree cone angle that will interchange with any of our 192 kHz sonar units.
keyboardthe initial pulse length desired and then press the PULSE key. For example, to set the initial transmit pulse length to 1 00 microseconds, press 1 - 0 - 0 - PULSE. This will override the micro-computer's selection and set the initial transmitter pulse length to 100 micro-seconds. P = 100 will be printed at the bottom of the paper to signify that the entry has been confirmed. (Note: When an initial transmit pulse length is set, this length will be fixed for all depth settings until changed.
Recording individual fish with an "arched" signaturecan usually be accomplished at trolling speed with the Sensitivityknob at the ¾ point, or higher.

used to outline the bottom contour which might otherwise be hidden beneath trees and brush; it can also give clues to the composition of the bottom. A hard bottom returns a very strong signal causing a wide gray line. A soft, muddy or weedy bottom returns a weaker signal which is emphasized with a narrow gray line. Do not advance the control too far or it will gray line on the target completely, showing no black, which makes the target difficultto see.

washed periodically with mild soapy water to remove any accumulated road grime or oily film. This is essential to have good contact between the transducer and the water. Periodically, the rubber roller on the paper drive should be cleaned with a cloth dampened with alcohol to improve the friction on the metering roller drive. Don't open the case or the transport assemblywhen the unit is running. The stylus holder and stylus may be damaged or personal injury may result. fish signals or other targets.
place near the top of the chart paper. A zero adjust control has been placed on the back inside wall of the X-1 6 near the upper left hand corner so that the zero line position may be adjusted on the paper. Open the case front and look for the decal marked "ZERO ADJUST". You may have to pull the paper transport assembly down to see the decal for the first time. Push the transport closed and turn on the unit. (CAUTION — Keep hands away from the stylus belt and stylus. High voltage is present.

Latch both catches on the top. 12. Turn the unit on. Move the Chart Speed knob fully clockwise. Watch the paper long enough to be sure it is moving smoothly and evenly across the platen. If the paperflutters or begins to run "uphill", repeat step 6.
Special Note: The stylus may be damaged if the transport assembly is pulled down unless the stylus has been moved to the back side of the 7. Slide a fresh roll of Lowrance chart paper in position on the supply side shaft on the right side of the platen assembly. The paper must spool off the bottom of the roll. (See Figure 30). platen. 4. Pull out and down on the tab at the top center of the platen assembly to expose the paper spools. (See Figure 26).
