General Information - Standard Horizon FF520 Owner's Manual

1. INTRODUCTION
This chapter provides basic information in becoming familiar with the advanced functions
of the FF520 before you start using it combined with the STANDARD HORIZON GPS
chartplotters.

1.0 GENERAL INFORMATION

The STANDARD HORIZON GPS chartplotters combined with the sonar performance of the
FF520 creates the most advanced marine navigation system available. This Owner's
Manual covers the Fish Finder functions of the FF520 when used with the STANDARD
HORIZON GPS chartplotters.
The FF520 advanced features include:
· A-scope (displays Sonar Echo in real time)
· Auto or Manual, with preset modes (Fish, Cruise, Autorange, Bottom Lock, Manual)
· 2x and 4x Zoom (capability to magnify any part of the Fish Finder image of a fixed rate)
· Bottom Lock (capability to magnify a user defined range around the bottom)
· White Line (help distinguish between fish and bottom, when fish is swimming close to
the bottom)
· Sensitivity Time Control (STC) (allows reducing or eliminating surface clutter)
· Interference rejection (allows reducing interference from other boats/Fish Finders)
· Noise Filter
· Fish Symbol feature
· Transducer ID (automatically selects power output and parameters for best perfor-
mance).
· Dual Frequency: 50 and 200kHz with the capability to display the two frequency at the
same time.
· Dual Power output: 500/1000W (4000/8000Wpp) depending on the transducer con-
nected. Refer to Par. 6.1 "Optional Transducers".
· Max Depth: 1KW - 1200Ft (365m) at 200kHz, 4000Ft (1219m) at 50kHz
500W - 700Ft (213m) at 200kHz, 1500Ft (457m) at 50kHz
· Min Depth: 2.5Ft (0.8m) at 200kHz, 5Ft (1.6m) at 50kHz
· Speed Sensor (if available on transducer)
· Dual temperature inputs Sensor (One channel TEMP1, Optional second channel
TEMP2) - (if available on transducer)
· Trip log
· External buzzer connections (buzzer not supplied)
· Show shallow Alarm, Depth Alarm, Temp Upper, Temp Lower
Transducer ID is only available with STANDARD HORIZON DST520, DST521, DST523, DST525,
DST526, DST527 and DST528 transducers.
