Use this menu to
calibrate the water
temperature and the
boat speed.
Select MAIN MENU -
SETUP - INSTALL -
CALIBRATION to
display the calibration
menu.
Calibrating the
Temperature
The factory settings
should be sufficiently
accurate for normal usage. However to calibrate the
temperature readout, first measure the water
temperature.
Then, to calibrate the setting, select TEMPERATURE
then press to display the temperature readout box.
Press or to increase or decrease the value to
match the measured temperature.
(To change the temperature units between °F
(Fahrenheit) or °C (Celsius), use the SETUP - UNITS
menu (see section 4-2).
Calibrating the Speed
Use this to calibrate the boat's speed and log.
Calibration may be required because different hull
shapes have different flow characteristics.
Obtain an accurate measurement of the boat's speed
from a GPS receiver; by following another boat
travelling at a known speed; or by making a timed
run over a known distance.
Note that for accurate calibration:
·
The speed from a GPS receiver should be
greater than 5 knots.
·
The speed from another paddlewheel
transducer should be between 5 and 20 knots.
·
Best results are achieved in calm conditions
where there is minimal current (best at high or
low tide).
Use or to highlight the SPEED option, then press
to display the speed readout box. Press or to
increase or decrease the readout to match the
independent speed value.
Important
This option resets all of the following settings and
resets them to the manufacturer’s default settings.
Settings relating to water temperature and boat
speed are for the FISH 4150 only. Speed and distance
are related. For example, if knots are chosen as the
speed units, then distance is always measured in
nautical miles.
To reset the fishfinder to the manufacturer's default
settings, power off the fishfinder. Then hold and
power on while holding it.
The message “RESET TO FACTORY DEFAULTS?”
appears. If “YES” is highlighted, do nothing and the
fishfinder resets to the default settings. Otherwise,
press or to select YES.
