Printed in Japan FIRST EDITION F : : FEB. OME-72390 (DAMI) CI-80 SAFETY INSTRUCTIONS WARNING ELECTRICAL SHOCK HAZARD Do not open the equipment. Immediately turn off the power at the switchboard if water leaks into the equipment or something is dropped in the equipment. Fire or electrical shock can result if a liquid spills into the equipment. [. . . ] Depth can be set either manually between 50 and 300 meters in resolution of 50 meters or automatically. ECHO LEVEL SHIFT: Sets echo intensity level, between 1 and 100 in resolution of 1. NOTE: ECHO LEVEL SHIFT is not related to amplifier gain; it does not affect detection of tide speed or ship's speed. Figure 16 ECHO menu TRK Menu Sets up the course plot display. PLOT RANGE: Sets latitude and longitude range of course plot, between 0. 1 and 5. 0 miles in resolution of 0. 1 mile. PLOT MODE: You may select either Head-up (bow at top of display) or North-up (North at top of display) orientation. TRACK DISPLAY: Turn on/off trackline display. Figure 17 TRK menu 17 MARK Menu This menu sets measuring conditions for tide vector and target point mark. PRESET REFERENCE VALUE: Sets the effect of tide on the target point mark. TIDE HISTORY: Sets tide vector plotting interval, among 0 (turns off tide vector display), 15 sec. (1/4 min. ), 1 min. , 5 min. , 10 min. , 30 min. , and 60 min. Figure 18 MARK menu AVR Menu The AVR (Averaging) sets averaging time for measuring raw speed, tide and water tracking data, to smooth out random variation of data. SHIP SPD AVR: Raw speed data (from connected sensor) may change randomly due to receiving conditions, etc. Speed averaging is available in times of 15 sec. , 30 sec. , 60 sec. , and 90 sec. The default setting is 15 sec. , which is suitable for most conditions. TIDE AVERAGE: Direction and speed of a tide changes with time, place and depth. Therefore it is important that the current indicator not respond to quickly or too slowly to tide movement. Tide averaging time is available between 0 and 5 minutes in the nearest minute. ("0" is for use of raw tide data. ) In most cases "2 min. " provides excellent results. Too high a setting may prevent detection of rapid changes in tide movement, such as a current rip. WT SPD DEPTH: Sets measuring depth of water speed in the water tracking mode. The default setting is two meters, and it is suitable for most conditions. Change the setting when water tracking speed display becomes unstable (due to air bubbles, etc. ), or to measure water tracking speed at a given depth. Figure 19 AVR menu 18 OPERATION Basic Operating Procedure Turning on the system 1. The display unit conducts a check of the system, displaying the results about 40 seconds after turning on the power. Figure 20 Display unit and transceiver unit Selecting operating mode Press the MODE key to select operating mode among water tracking, ground tracking, or automatic selection. Selected mode appears at top right corner on the display. N: Nav Figure 21 Location of operating mode indication on echo display 19 Ground Tracking Mode: Shows absolute ship and tide movements based on ground. [. . . ] · "TIDE AVERAGE" on the AVR menu may be set to "0". · cables of other equipment may be too near transducer cable. 30 Self Tests, Demonstration Display The CI-80 has four self tests and a demonstration display which check the system for proper operation. Display the system menu 1. While pressing and holding down the TRIP key, press the MENU key. Conducting self tests MODE CALB 1. Press / / to select SELF TEST to select test.
