In general this will not damage the equipment but it can lead to it resetting, or momentarily may result in faulty operation. This can then be avoided by turning off the FF50 prior to starting the boat engines for instance.
• Some products generate high voltages, and so never handle the cables /connec- tors when power is being supplied to the equipment. • Always report any EMC related problem to your nearest JRC dealer. We will use any such information to improve our quality standards.

SECTION 1 Function The Color Fish Finder FF50 is a system that uses the basic principles of sonar to show lake or seabed conditions and to detect fish. It consists of a transducer, which is installed on the transom, or thru-hull transducer, and a display unit.
Features DUAL FREQUENCY Because two frequencies, 200 kHz and 50 kHz can be used, the areas used to search for schools of fish is more flexible and information on the type of fish or seabed can be better determined by comparing echoes of each frequency. The display in the dual-frequency mixed mode is also available.
Components When unpacking your FF50, you should find the following standard equip- ment in the carton. If any items are missing, please notify your JRC dealer imme- diately. Standard Equipment No Description Model No. Qty. Remarks Fish Finder JFC-500 Transducer...

To mount the unit, remove the mounting yoke from the unit by loosening the yoke knobs on each side of the FF50. Attach the bracket to the desired mounting surface with the setting screws (o6x25SUS, 4Qty.) included in the kit, refering to Figure 1-2.
Console Mounting/ Surface Mounting CAUTION Make sure there no hidden electrical wires or other items behind the desired location before proceeding. Also check that you have free access for mounting and cabling. 1) Select a mounting location: a clear, flat area of at least 8"(203mm) wide by 8" high, having 5.5"(140mm) depth behind the panel.

CAUTION Do not position the sensor farther into the water than necessary to avoid increasing drag, spray, and water noise and reducing boat speed. ➄ Using the vertical adjustment space on the bracket slots, slide the sensor up or down to provide a projection of 1/8" (3mm). Tighten the screws (see Figure 3-9).
Cable Routing Route the sensor cable over the transom, through a drain hole, or through a new hole drilled in the transom adove the waterline. CAUTION Never cut the cable or remove the connector; this will void the warranty. WARNING Always wear safety goggles and a dust mask.

Installing the Thru-Hull Transducer You may wish to drill a 1/8" (3.2 mm) pilot hole from the inside to assure access to the housing nut and clearance for the cable. Drill from the outside if there is a strake or other hull irregularity. Use caution when sanding or cleaning as harsh cleaning solvents such as acetone weaken some epoxy resins and may damage the transducer.
Connecting DC Power WARNING Do not touch the ground terminal and vessel ground on the display unit at the same time without the ground terminal earthed. Otherwise, you may suffer an electric shock.

Echo Sounding As the boat travels, echoes returning to the transducer are received which continuously update the FF50 display. Receiving and identifying echoes from fish can depend on several factors including: •Species of fish •Number and size of fish...
• When the seabed is made up of coral, wrecks, or rock piles, the irregular surfaces and various angles of the seabed return closely spaced echoes. The bottom line on your display appears with irregular long tails. Seabed Displays The FF50 high-resolution display provides accurate representations of various bottom conditions. Hard (Sand)
GPS/DGPS Basics The Navstar/GPS system is a satellite-based radio navigation system designed to provide global, continuous 24 hour-per-day, all weather, accurate position data for navigators. The GPS(Global Positioning System) is based on a GPS sensor’s ability to accurately measure the propagation time of signals transmitted from orbiting satellites in your sensor.
Differential GPS (DGPS) The differential GPS comprises a reference station with its position(latitude and longitude) accurately known, a beacon station for radio broadcasting of DGPS correction data, and user-owned GPS sensor equipped with a differential correcting function. The GPS sensor is used to fix the position of the reference station whose position is accurately known and to eompare this with the actual reference station position to get range errors.
