All screens in this manual are simulated. INTRODUCTION The X-75 and X-85 are the latest members of the Lowrance family that combines a high performance sonar with a wide, high definition screen. Using menu features and "soft-key" operation, these units are also easy to use. The wide screen shows the underwater world with high resolution and detail. The display and keyboard are also lighted for night operation. They have digital boat speed, surface water temperature, and distance travelled (log) screens. (Requires optional ST-TBK speed/temperature sensor for both speed and temperature screens.) The optional SAM-50HPD gives these units 50 kHz capability.The 3000 watt transmitter in the SAM-50HPD plus the low frequency gives the units far more depth penetration. This, along with the wider cone angle transducers, makes 50 kHz operation ideal for ocean and Great Lakes use.

Supertwist LCD 240 vertical x 240 horizontal 57,600 total pixels INSTALLATION MOUNTING Install the unit in any convenient location, provided there is clearance behind the unit when it is tilted for the best viewing angle. Holes in the bracket base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back of thin fiberglass panels to secure the mounting hardware. Make certain there is enough room behind the unit to attach the power and transducer cables. The gimbal bracket will also accept the GBSA-1 swivel bracket adapter that lets you rotate the unit a full 360°. The smallest hole that allows one power or transducer connector to pass through is 3/4". After the hole is drilled, push the transducer connector up through the hole first, then drop the power cable down through it. After the cables have been routed, fill the hole with a good marine sealing compound. Offset the bracket to cover the hole. Route the power cable through the slot. Break out one of the holes in the back of the bracket for the transducer cable. FRONT POWER CONNECTIONS The unit works from a twelve-volt battery system. For the best results, attach the power cable directly to the battery. You can attach the power cable to an accessory or power buss, however you may have problems with electrical interference. Therefore, it's safer to go ahead and attach the power cable directly to the battery. If the cable is not long enough, splice #18 gauge wire onto it. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make certain to attach the in-line fuse holder to the red lead as close to the power source as possible. For example, if you have to extend the power cable to the battery or power buss, attach one end of the fuse holder directly to the battery or power buss. This will protect both the unit and the power cable in the event of a short. It uses a 3-amp fuse. IMPORTANT! Do not use this product without a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your warranty. If you're installing a speed/temperature sensor, read it's mounting instructions. Route the sensor's cable to the power cable and plug it into the connector marked "SPEED/TEMP CABLE" To Sonar Unit POWER CONNECTIONS RED WIRE BLACK WIRE 3 amp FUSE TO SPEED/TEMP OR TEMP SENSORS (Not included) 12 VOLT BATTERY SPEED/TEMPERATURE SENSORS This unit accepts up to three temperature sensors which can monitor surface water, live well, air, and virtually any other temperature. You do need to be careful when purchasing the temperature sensors, however. Each temperature sensor has its own "address". The sensors are labeled "Water", "T-2" (or Temp-2), and "T-3" (or Temp-3). If you want two (or more) temperature readings, you'll need to use the proper sensors. For example, you can't use two T-3 sensors. The sensors that will fit these units are: TS-1BK TS-2BK TS-3BK TS-12BK ST-TBK One sensor for "Water" temperature display. One sensor for "T-2" temperature display. One sensor for "T-3" temperature display. Two sensors for "Water" and "T-2" temperature displays. One speed sensor and one temperature sensor for "Speed" and "Water" displays. You can combine these sensors in many combinations. See the list on the following page for temperature and speed sensor combinations. Sensor Chart (Note: Do not use these sensors in any other combination.) ST-TBK = 1 speed sensor and 1 temperature display ST-TBK + TS-2BK = 2 temp sensors and one speed sensor ST-TBK + TS-2BK + TS-3BK = 3 temp sensors and one speed sensor TS-1BK = 1 temperature sensor TS-12BK = 2 temperature sensors or TS-1BK + TS-2BK = 2 temperature sensors TS-12BK + TS-3BK = 3 temperature sensors or TS-1BK + TS-2BK +TS-3BK = 3 temperature sensors Here's some sample wiring diagrams: TS-12 BK Two Temperature Sensors (Water and T-2) POWER CABLE TS-12 BK TS-3 BK Three Temperature Sensors (Water, T-2, and T-3) POWER CABLE ST-TBK TS-2 BK TS-3 BK Three Temperature Sensors plus Speed (Water, T-2, T-3, and Speed) POWER CABLE LOWRANCE 192 kHz TRANSDUCER POWER TO SAM-50HPD (NOT INCLUDED) CONNECTORS The diagram above shows the three connectors on the back of the sonar unit. Looking at the back of the unit, the 192 kHz transducer connector is at the far left. Plug the 192 kHz transducer in here. The center connector is for the power cable. The connector at the far right is for a serial cable that is included with the SAM-50HPD. This is the cable that allows the SAM to communicate with the sonar unit.
