%CHOSOUNDERFREQUENCY - 50 kHz or 200 kHz can be selected to suit the

task. 200 kHz is for general purpose and offers optimum discrimination

and a narrow transmitter beam with a 15° opening. 50 kHz is for search-

ing in a wider area, determining bottom conditions and going the deep-

est. The transmitter has a wide transmitter beam with a 45° opening.

%VENTMARKER - allows the user to set a vertical marker on the screen at

the current ping to indicate a school of fish, etc.

%XPANSIONZOOM - this function allows you to take a closer look at a

particular section of the water underneath your boat. You can expand the

view near the bottom (Bottom expansion) or near the Variable Range

Marker (VRM expansion). The amount of expansion can be adjusted in

’Expansion window’, ’Presentation setup’.

'AIN - is another way of saying "sensitivity", or possibly "volume". In-

creasing the gain setting of the EQ32 MKII will allow you to see smaller

and deeper targets. If the gain is set too high, however, you will begin to

see "noise" and unwanted targets. Generally speaking, you want to set

the gain control just below the point that you begin to see speckles of

"noise" on the screen.

,/'SPEEDCALIBRATION - the unit is preset to receive 19000 pulses per

nautical mile from the log transducer (paddle wheel). However the figure

might have to be changed to compensate for various transducers and ac-

tual waterflow passing the transducer. The correct pulse rate is calculated

by: 19000 x indicated speed (eg. 4kn)

= 15.200 pulses/nm

actual speed (GPS) (eg. 5kn)

-EASUREMENTUNITS - refers to the measurement unit used in the range

display. The user may select the displayed units to be one of the follow-

ing: meters, feet or fathoms.

-%.5 - the selection of main menus will be shown in the upper part of

the screen. The user may move through the menus and make selections

by means of the cursor key and the [ENT] key.
