GENERAL SAFETY WARNINGS
(continued on next page)
i
General Safety Warnings – 1/2
(1) THE REAR–PANEL TRANSDUCER CONNECTOR RECEPTACLE IS
EMITTING EXTREMELY HIGH VOLTAGE RADIO–FREQUENCY PULSES
WHEN THE EQUIPMENT IS TURNED ON.
THE CONNECTOR IS NORMALLY COVERED WITH A SCREW–LOCKED
PROTECTIVE RUBBER CAP WHEN THE EQUIPMENT IS INITIALLY
DELIVERED.
TO AVOID COMING INTO CONTACT ACCIDENTALLY WITH ANY OF THE
CONNECTOR PINS, BE SURE TO PLACE THE PROTECTIVE CAP OVER
THE RECEPTACLE WHENEVER THE TRANSDUCER IS UNPLUGGED.
LOCK THE CAP WITH THE TWO SCREWS ATTACHED.
(2) TO COMPLY WITH THE RELEVANT WHEEL–MARK TYPE APPROVAL
REGULATIONS, THE EQUIPMENT MUST BE OPERATED USING ONE
OF THE TRANSDUCERS SPECIFIED IN THIS MANUAL. OPERATION
WITH A TRANSDUCER OTHER THAN A SPECIFIED ONE IS NOT
OFFICIALLY APPROVED, AND THE RESULTS OBTAINED WITH SUCH A
TRANSDUCER MUST NOT BE USED FOR NAVIGATIONAL PURPOSES.
(3) THE ACCURACY OF THE ON–SCREEN DEPTH READOUT IS
AFFECTED BY WATER TEMPERATURE, SALINITY, DEPTH AND
OTHER UNDERWATER CONDITIONS AS WELL AS THE SHIP’S
ROLL AND PITCH, HEEL AND TRIM.
TAKE THESE POSSIBLE ERROR–CAUSING FACTORS INTO
CONSIDERATION WHEN USING THE DEPTH READOUT, SUCH AS
WHEN NAVIGATING SHALLOW AREAS OR IN APPLICATIONS
WHERE ACCURATE DEPTH READING IS CRITICAL.
(4) DURING SHALLOW WATER OPERATION, THE EQUIPMENT MAY
OCCASIONALLY READ TWICE THE ACTUAL DEPTH BY LOCKING
ONTO THE SECOND BOTTOM ECHO.
THE DIGITAL DEPTH READOUT SHOULD ALWAYS BE COMPARED
WITH THE GRAPHIC BOTTOM INDICATION OR WITH SOUNDINGS
DATA IN OFFICIAL NAUTICAL CHARTS TO DETERMINE THE TRUE
DEPTH.
TOTAL RELIANCE ON THE DIGITAL READOUT ALONE FOR DEPTH
INFORMATION IS DANGEROUS AND MUST BE AVOIDED.
See paragraph 7.4.2 for more information on the second bottom echo.
(5) WHEN THE DEPTH REFERENCE INDICATION IS SET TO “BELOW
KEEL,” BE SURE TO ENTER THE APPROPRIATE KEEL OFFSET TO
AVOID ANY MISUNDERSTANDING ABOUT THE DEPTH READOUT.
See paragraph 8.10.7.3 for more information on keel offset.
