alarm will sound at 2 beeps per second.
NOTE: To fully deactivate an alarm, reset it to zero. Press-
ing the “ON / OFF MODE” keypad temporarily deacti-
vates the alarm. To reactivate the alarm press the “ON /
OFF MODE” keypad until the depth reading appears.
3. Keel offset. Pressing the “ON / OFF MODE” key-
pad again displays the “KL” keel offset setting. This
can be set so that the depth sounder either shows the
depth below the keel or the depth below the transducer.
Press the up or down arrow keypads to adjust the read-
ing to the desired depth no more than 19.9 ft. For ex-
ample if the bottom of the keel is 2ft below the trans-
ducer and you want the depth sounder to read the depth
below the keel, the display should be adjusted to read
2.0 FT.
NOTE: Once a keel offset is programmed, the shallow
and deep alarms will be activated by the depth below
the keel.
4. Units. Pressing the “ON / OFF MODE” keypad again
displays “Un” on the LCD indicating the units mode.
Press either the up or down arrow keypads to set the
units desired to feet (FT), meters (M), or fathoms (F).
These units once set, will remain the same for all modes.
Pressing the “ON / OFF MODE” keypad again returns
the depth sounder to normal operation.
H. Gas Vapor Detector
The Gas Vapor Detector is optional equipment on the
348 Vista. The gauge mounts in the dash. Additional
information can be found in Section I-1H in this manual.
I. Engine Hour Meter
Engine hour meters are optional on all Vista® models
and provide a numeric record of elapsed engine operating
time. This information is important in determining sched-
uled maintenance intervals, ships log data, cruise infor-
mation, etc. The hour meters are located in the engine
compartment on all engines.
J. Ignition Switch
The ignition switch has three positions: OFF, RUN, and
START. The START position is spring loaded and the
key should be held in this position until the engine starts.
The key will return to the RUN position once released.
Always turn the key to the OFF position when the engine
is not running. This will prevent discharging of the batter-

ies. Additional information on ignition switch operation is
covered in Section A - Operation of this manual.
K. Engine Synchronizer Gauge
An engine synchronization gauge is standard on the 348
dash. It is located between the tachometers on the dash.
This instrument compares the electrical signals gener-
ated by the engines and converts those signals to a vi-
sual meter indication of engine speed difference. The
meter movement responds to changes in throttle posi-
tion.
This instrument does not physically synchronize the en-
gines, but only provides a visual indication so the opera-
tor can take corrective action. See Section F-2 - Control
Operation and the engine manufacturer’s literature for addi-
tional information on throttle usage and engine synchro-
nization.
L. Alarm Systems
An engine alarm system is installed on the 348 Vista
(gas or diesel engines). This is an audible alarm that is
mounted in the helm area; it is actuated by engine water
temperature and engine oil pressure senders. The alarm
will sound in the event of low engine oil pressure or high
engine coolant temperature.
The engine alarm will sound during engine start-up, or
whenever the ignition switch is positioned to ON and the
engine is not operating. The alarm sounds under these
conditions because engine oil pressure is low; the alarm
will cease to sound as soon as engine oil pressure rises
to the proper level.
NOTICE
The engine alarm monitors only engine water tem-
perature and engine oil pressure. Always main-
tain a close visual watch on the drive(s), transmis-
sion(s), engine fluid levels, bilge water level, etc.
Refer to the engine manufacturer’s literature for
additional information.
M. Navigational Packages (Optional)
Also available are optional navigational packages. See
Figure E20. Navigation Package I includes the Raytheon
VHF-210 radio and Raytheon GPS/Loran-398.
Navigation Package II option is also available on the 348
Vista and it includes Raytheon VHF-210 radio and
Raytheon Radar System with GPS interface.
