USING THE IDF SERIES
CONTROLS AND OPERATIONS
CONTROLS AND OPERATIONS
POWER: Press the PWR/Light, switch on the front panel of the IDF unit to turn the
unit on, a second push will turn the backlight on. Push a third time to turn the
backlight off.A long depression of the PWR/Light switch will power the IDF off.
SENSITIVITY: The logarithmic nature of the Sensitivity Control allows improved
fine tuning of the unit‘s gain. From the zero setting to the 32 setting of the
sensitivity key the gain is increased from zero to full.At the 10 Position the
gain is approximately 20% with full gain being achieved at the 32 setting as
shown on the display.
RANGE: The unit powers up on the 40' RANGE and can be changed to the
80' or 120' RANGES by depressing the RANGE button. The selected RANGE
will be displayed in the center of the
IDF. A shallow RANGE selection may not
display a bottom return.
SUPPRESSION: The unit will power up without SUPPRESSION.To add SUPPRESSION,
press the S
UPPRESSION key. Pressing the key again will eliminate SUPPRESSION.
S
UPPRESSION
provides an advanced level of control over the amount of visible detail on the unit. You can choose the setting that works best for your
style of use.
With S
UPPRESSION
set to OFF, the
IDF
displays increased detail, showing more
thermoclines, structure, fish and even your bait when it falls within the sonar
cone. However, this extreme sensitivity requires you to optimize the installation
of your unit and transducer so that “noise” generated by a moving boat is not
picked up by the fishfinder.
With S
UPPRESSION
set to ON, excessive clutter often caused by interference from
other fishfinders, your boat‘s engine, or from noise generated by the hull at
high speeds is reduced in the display. This provides a cleaner image on the display in most cases. Adjust SENS (S
ENSITIVITY
) for best display at various speeds,
from trolling on up to your boat's maximum speed with RealTime™ Sonar.
BACKLIGHT ON: To turn the display BACKLIGHT on press the Power Light
switch once.To Turn the Backlight off, press the Power Backlight Switch momentarily. Continued Depression will turn the Unit off.
