    The iFINDER listens to signals from as many satellites as it can see above the horizon, eliminates the weakest signals, then computes its loca- tion in relation to the remaining satellites. Once the iFINDER figures its latitude and longitude, it plots that position on the moving map shown on the screen.

These Custom Map Files (file format *.lcm) can also be shared be- tween iFINDERs, other Lowrance GPS or sonar/GPS units and per- sonal computers. You make your own Custom Map Files with our MapCreate software, but you don't have to.

    A minimum of three satellites are required to determine a 2D fix. The system requires signal reception from three satellites in order to determine a position. This is called a 2D fix. It takes four satellites to determine both position and elevation (your height above sea level — also called altitude).

    WAAS reception, but terrain, foliage or even large man-made structures can sometimes block the WAAS signal from ground receivers. You'll find that using your GPS receiver is both easy and amazingly accurate. It’s easily the most accurate method of electronic navigation available to the general public today.

  • Page 19: Section 2: Installation & Accessories, Power, Batteries

    Installation & Accessories Power The iFINDER operates from AA batteries or on 3 volts DC using an optional external power cable with a cigarette lighter adapter. When the power cable is used, the iFINDER automatically switches to exter- nal power. If the external power fails, the unit will switch to battery power.

  • Page 20: Battery Installation

    Do not mix different battery types. Mixing battery types may cause leak- age. (For example, don’t use both alkaline and NiMH batteries at the same time, and don't use standard alkalines with rechargeable alkalines.) Battery Installation Turn the unit over so that the back is facing you. With your thumb or nail, pull back on the small clip to release the battery cover latch as shown in the following images.

  • Page 21: Cigarette Lighter Power Adapter

    Replace battery compartment cover. Align tabs with slots in the base (left). Press latch firmly until it clicks (right). Cigarette Lighter Power Adapter To use external DC power, plug the power cable's cigarette lighter adapter into a cigarette lighter receptacle. Next, pull aside the rubber cover on the bottom of the unit and insert the other connector as shown in the following image.

  • Page 22: Nmea Cable Connections, Mmc Or Sd Memory Card Installation

    NMEA Cable Connections NMEA is a standard communications format for marine electronic equipment. For example, an autopilot can connect to the NMEA interface on this unit and receive positioning information. The unit can exchange information with any device that transmits or receives NMEA 0183 data. To exchange NMEA data, Lowrance offers an optional data only cable and a power/data combo cable: The PC-DI7 is a NMEA/serial communications cable.

    Section 3: Easy Mode Operation This section addresses Easy Mode operation for the iFINDER's main GPS functions. The principles are the same in both operating modes, so this discussion also serves as a good introduction to Advanced Mode work. Before you turn on the iFINDER, it's a good idea to learn about the dif- ferent keys, the three Page screens and how they all work together.

    North is at the top of the screen. If you hold the unit facing north, you can use it to see which satellites are obstructed by obstacles in your immediate area. The GPS receiver is tracking satellites that are in bold type. The receiver hasn't locked onto a satellite if the number is grayed out, which means it isn't being used to resolve the position.
