Connect Power
Your MarCum Flasher comes virtually ready to fish. All you need to do is hook
up the positive and negative leads from the power cord to the battery. To
access the battery, open the battery access door at the rear of the unit.
Connect the red wire to the red terminal and the black wire to the black
terminal on the battery.
Deploy the Transducer
When used in conjunction with the retractable pivoting transducer arm and
rubber stopper, the transducer will automatically level itself in your ice
hole. To begin operation, take the transducer out of the recessed holder, and
rotate the adjustable ice arm out from inside the shuttle. Extend the
transducer arm, (the cable should already be threaded through it with a
stopper in place) and deploy the transducer into the water.
Power up the system
The
Range select knob is used for turning the unit on or off, as well as choosing
the correct depth range. The Flasher offers four depth ranges to choose from
that can be selected by rotating the knob clockwise. The depth ranges are 20,
40, 80, or 160 feet. The depth-range setting is determined by turning the unit
on and turning the Gain knob looking for a solid return (band of light)
indicating the bottom on the display.
Adjust the Gain
The best
Gain setting is achieved by turning up your Gain from 0 until you receive a
clear and steady bottom reading. If you’re looking for your lure or bait, turn
up the gain until you just begin to display your bait without it fading or
flickering on the screen. The lower the sensitivity, the narrower the display
segments, the easier it is to distinguish targets.
Bottom Return
Hard-bottom readings (rock or gravel) will be displayed by a wide band of a
RED light indicating a strong signal. Conversely, a soft bottom (mud or silt)
will return a weaker signal and will result in a narrower RED band or even a
combined RED and GREEN band. A soft bottom with weed growth will often appear
as a narrow RED or GREEN band combined with both solid and broken YELLOW
segments indicating weeds.
Jig Return
The Flasher will pick up and display small objects like jigs, split shot, or swivels. When tuning the unit to display your lure or bait, lower the object to the desired depth and turn up the GAIN until you see the jig on the display. It is important that the GAIN be set so it displays the jig as you raise or lower it.
Zoom Function
When the ZM key is depressed, the circular display is divided in half. The
right half of the display (12 to 6 o’clock on the dial) will become the entire
depth range you chose when turning the depth range knob. The left side of the
display is the Zoom window portion. If the unit will not go into zoom mode,
turn the GAIN up to 10. Once Zoom is active, turn the GAIN back down to a
normal operating level. The M1 has a bottom lock Zoom Only.
Up/Down Buttons ( M3L & M5L Systems Only )
When you first depress the ZM button and then the Up/Down Button, you will see
two blinking yellow lights that are 5 feet apart on the yellow scale on the
flasher dial. You can move the zoom window up or down to your desired depth
range. You can select a 10-foot zoom window by pressing the zoom button a
second time and depressing the down button. You will now see a 10 foot zoom
window and can move it to your desired depth.
IR Button
When other sonar units are causing interference to the display, activate the
IR feature by depressing the IR key. When you press the key, a beep will be
heard. There are 12 levels of Interference Rejection, and each press of the
key will change the level of Interference Rejection. The correct level of IR
will be achieved when the display is clear of the display clutter.
NBT Button ( M5L Systems Only )
This feature allows you to change your transducer cone angle from 20° to 8°.
The 8° cone angle should be used in deep water, shallow water with heavy
weeds, or when fishing in close proximity to other anglers with heavy
interference.
SFL Button ( M5L Systems Only )
This feature
allows the user to improve target separation to 3/4 of an inch and still
utilize the full-screen display. When the SFL key is depressed, a RED LED will
light to indicate that the SFL feature has been activated. Utilizing Superfine
Line changes the transmit pulse, narrows the display segments, and improves
the target separation to 3/4 of an inch.
Charging
To charge, simply couple the end of the charger with the end of the wiring harness. It is also normal for the light on the charger to be green if it is just plugged into the wall. When it is plugged into the wall and battery, you will see a red LED light to appear on the charger. If the light is red, the battery is being charged. When your battery is fully charged, this red light will change to green.
