The 3500 is a high-performance digital sonar. It works only off the bottom signal
and it's operation is completely automatic. There are no sensitivity or noise con-
trols. All of this is made possible by the computer built inside. This unit fits in a
standard 2 1/8" (54 mm) hole used by most marine equipment manufacturers.
Mounting
The 3500 needs at least 2 1/2" (64 mm) of space to mount on any flat panel or
dash. To install the unit, also make certain there is at least 3 3/4" (95 mm) from
the front of the dash to any obstruction behind the dash. Check to be sure there
is room to route the power and sensor cables. The maximum usable dash thick-
ness is 1 1/8" (28.5 mm).

When you determine the location for the 3500, drill a 2 1/8" (54 mm) hole in the
dash. Slide the 3500 through the hole from the front of the dash. Align it so that
it's straight, then tighten the two screws with a phillips-head screwdriver.
To prevent damage to the unit, DO NOT use a pneumatic/power screwdriver.
Use a hand-held screwdriver and the torque should not exceed 7 in lbs. Also,
when removing the unit, do not back the screws out of the case. Damage to the
faceplate will result. We recommend backing off the screws one complete turn
before attempting to remove the unit. If further loosening of the screws is re-
quired, do so in half-rotation increments.
Place the push-button into the holes in the bezel and snap it on to the 3500.
The unit is now ready for wiring.

OPERATION Since the 3500 is an automatic sonar, all you have to do is turn it's power on. It will give you a water depth reading within seconds. Once it finds the bottom, the 3500 locks onto it and automatically adjusts the sensitivity and noise suppression circuits. - Page 3 BLACK SPEAKER CABLE TRANSDUCER CABLE TRANSDUCER WHITE BLACK 12-VOLT BATTERY DASH POWER CABLE LIGHT SWITCH (NOT INCLUDED) WHITE BLACK 12-VOLT BATTERY POWER SWITCH (NOT INCLUDED) 3-AMP FUSE POWER SWITCH (NOT INCLUDED) 3-AMP FUSE...
