Introduction; Function; Feature - JRC JFE-700 Instruction Manual

1. Introduction

1.1 Function

The JFE-700 Echo-Sounder consists of a transducer mounted on the bottom of the ship's
hull and a main unit that displays information on the depth and formation of the seabed.
This information is gained by using ultrasonic waves sent from the transducer that are then
reflected off the sea bottom and picked up again by the transducer. The JFE-700 also has
the following functions:
(1) depth alert, (2) power fail alert, (3) output of depth data, (4) output of depth and power fail
alerts.

1.2 Feature

The JFE-700 features the following:
• Three display modes; standard, history, and docking.
• Depth data for last 48 hours in memory to play back the past sounding information.
• Dual frequency mode and two transducers are available in option. (*requires an optional
equipment)
Conforms to the IMO Performance Standard
• When the depth becomes shallower than a previously set value, a depth alert is issued by
buzzer and LCD display.
• When power is cut to the main unit, a power fail alert is issued by buzzer and LCD display.
• Contact signals can be output for both depth and power fail alerts.
• Data on depths can be output.
Digital Depth Display
• No need for time-consuming reading of depths using a scale against the profile of the
seabed on the paper. The current depth can be seen at a glance.
Self-Diagnostic Functions
• Self-diagnostic functions can be selected from a menu, improving ease of maintenance.
