Interference Rejection
Interference Rejection (IR) is a feature that allows you to fish around
other sonar systems without seeing a lot of random signal flashes or
slow-moving signals that rotate around your display. IR, as it is called,
is an automatic feature on the FLX-30 if the transducer is in the water
when the system is turned on. The sonar system listens for other sonar
signals and selects a clean setting for you.
To manually adjust IR settings, press in and hold the Gain Control
for two seconds while in any mode setting
other than “C.” Press again
within five seconds to sample another IR setting from 1 to 20. After
five seconds since the last press of the Gain Control, the FLX-30 will
resume normal operation.
There are 20 IR settings for each frequency. With seven frequencies
available, the FLX-30 offers 140 total Interference Rejection options.
Color Select
The FLX-30 includes five optional color palettes from which to
choose. Set the Mode Control to “C,” then press in the Gain Control
to cycle through the available palettes. See page 56 for an explanation
of each. The default setting is #3 (white, red, yellow, green).
Power Modes
The “P” on the MODE Control stands for Power. The unit will start
in the default setting, and the main dial will show the designation
“H-P” for High Power. Adjust the Mode Control to the “P” setting,
then push-in on the Gain Control once. The display will show
“M-P” for Medium power for two seconds. Push in on the Gain
Control again to switch to the “L-P,” or Low Power Mode, and
again to cycle back to “H-P.”
Depth Range Groups
The default range group is the Shallow or “S” ranges, which are
10, 15, 20, 30 and 40 feet. To go deeper with Manual Ranges, set
the Mode Control to the “R” setting and then push in on the Gain
Control once to select the Middle or “M” depth ranges. Now the
ranges are 50, 75, 100, 125 and 150 feet. Tap it again to go deeper.
The Deep or “D” depth ranges are 175, 200, 225, 250 and 300 feet.
Tap once more to go back to the default Shallow ranges.
