Professional Small Fishing Depth GPS Fish Finders / Tracker Finder

(KG-F306)

INTRODUCTION

System Summary

KG-F306 is a precision instrument designed for generating the reply echo

pulse for all types of depth sounders and fish finders. There are two modes:

Bottom Mode (BT) and Fish Mode (FI). BT is default mode.

Theory of Operation

KG-F306 receives pulse parameters from depth sounder / fish finder and

generates echo pulse to simulate the bottom or fish information and then

sends the information back to depth sounder or fish finder.

OPERATION

System Connection

NOTE System supply is DC24V(AC110/220V connect with adapter). Please use suitable power supply.

The input / output interfaces are both on the front and rear panel.

You can connect the input / output / ground interfaces with the transducer

3-core wires on operation panel respectively, and the transducer shield shall

be connected with the ground interface.

Also you can connect the input / output socket with the transducer 3-core

plug on the rear panel.

Rear Panel Operation

POWER ON/OFF

The POWER switch turns the SIM992 on and completely resets the

instrument all default modes and settings.

LOAD IMPEDANCE

There is low, medium or high load impedance to be selected.

Low load impedance is normally used with larger video and recording depth

sounder or fish finder.

Medium load impedance is used with most medium size depth sounder or

fish finder such as digital types with depth ranges up to 1000 feet.

High load impedance is used with small flashers and shallow water graphical

depth sounder or fish finder.

Screen Operation

LCD Display Explanation

When the KG-F306 is first turned on, the LCD display will look like this:

Input Frequency Input Width Input Period Input Amplitude

Echo Frequency Echo Width Echo Depth Bottom Mode

REPLY LEVEL

The REPLY LEVEL switch varies the replay level from 0.01mV to 50mV. The

AMPL VERNIER must be rotated to the maximum counter clockwise position

(CAL 1X position) for accuracy as indicated.

AMPL VERNIER

The AMPL VERNIER multiplies the setting value of the REPLY LEVEL switch.

If the REPLY LEVEL is set to 2mV and the AMPL VERNIER is set to 1.5, the

actual reply level is 3mV. Actual reply level = AMPL VERNIER × REPLY LEVEL

BOTTOM KEY

Press the BOTTOM key down and the bottom mode will appear, as indicated

by “BT” on the LCD screen. When the SIM992 is in the bottom mode, the

bottom echo frequency, echo width and echo depth can be set by depressing

the BOTTOM key repeatedly. Then the cursor can be moved left or right by

depressing ←/→ key in current cursor range and the values can be increased

or reduced by depressing / key repeatedly.

Echo frequency range: 0~599.9 kHz, Echo width: 0~3999 x 10 us,

Echo depth: 0~999.99 m

FISH KEY

Press the FISH key down and the fish mode will appear, as indicated by “FI”

on the LCD screen. When the KG-F306 is in the fish mode, the fish echo

frequency, echo width and echo depth can be set by depressing the FISH key

repeatedly. Then the cursor can be moved left or right by depressing ←/→

key in current cursor range and the values can be increased or reduced by

depressing / key repeat
