2 Depth alarm – Shallow mode: Pressing the
"ON / OFF MODE" keypad again displays the "SH"
shallow depth alarm setting. This is the shallowest
water that will activate the alarm. Press and hold
the up or down arrow keypads to adjust the
reading to the desired depth.
Depth alarm – Deep mode: Pressing the "ON /
OFF MODE" keypad again displays the "DP" deep
depth alarm setting. This is the deepest water that
will activate the alarm. Press and hold the "Up" or
'Down" arrow keypads to adjust the reading to the
desired depth. When the shallow depth setting is
read by the depth sounder, the "SH" will flash on
the LCD and the audible alarm will sound rapidly.
When the deep depth setting is read by the depth
sounder, the "DP" will flash on the LCD and the
audible alarm will sound at 2 beeps per second.
NOTE: To fully deactivate an alarm, reset it to
zero. Pressing the "ON / OFF MODE" keypad
temporarily deactivates 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"
keypad 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 reading to the desired depth
no more than 19.9 ft. For example if the bottom of
the keel is 2 feet below the transducer 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 " O N / O F F 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.
Engines, Drives and Instrumentation - Section E
Do not rely on depth sounder to avoid
submerged objects. Depth sounders provide a
relative indication of water depth only.
NOTICE
DO NOT depend solely upon the depth
sounder for water depth. It is important to have
navigational charts of the waters in which you
are operating.
4. Compass
A compass is standard on the 258 and 278 Vista
models. See Figure E10. The compass can provide
directional information when operating offshore, in
unfamiliar waters, or in adverse weather conditions.
Figure E10: Compass
After all personal equipment is installed, including all
electronics (VHF radio, GPS, chart plotter, etc.), the
compass must be properly calibrated. DO NOT rely
on the compass readings until initial adjustment
(compensation) has been performed. The boat has a
factory installed compass, the manufacturer's instruc-
tions are provided in the owner's packet. Most areas
have local companies that specialize in compass
adjustment. If unsure of the proper compensation
techniques, consider having the adjustment done
professionally to insure accuracy and confidence in
the compass.
NOTICE
During use, keep all extraneous metal objects
away from the compass. The close proximity of
metal objects (e.g., beverage cans) can cause
compass deviation.
