Lowrance electronic X-16 I1iI

be used to help alleviate this

condition.

LORAN-C

INTERFACE

A remarkable advantage of the

X-16 is its

ability

to print

Loran-C

coordinates in either

Time Differen-

ces (ID's) or Latitude and Longi-

tude. (NOTE:

The

X-16 has been

designed to use only the Lowrance

Loran-C

receiver.)

To connect the

Loran to the X-16, simply splice

the

white and black

wire on the X-16's

power

cable to the

white and black

wire on the Loran-Cs

power

cable.

(See Figure 2 on page 3.) After the

proper connections have been

made, turn on both the Loran and

the X-16. After the Loran has

acquired

the

signals, press

2nd - 0.

The Loran coordinates will imme-

diately be printed vertically

down

the paper. Either Latitude and

Longitude or Time Differences

(TD's)

will be printed on the paper

depending on the mode the Loran

is in. If 2nd - 0 is pressed and no

Loran is connected, the unit will

stop pulling paper

and printing for

approximately four seconds.

POWER BOOSTER

A power booster, Model

LPB-192, is available that will

increase the transmitter's output

power of the X-16. It can be

turned on or off by the keyboard

ducer cables. There should also

be enough room to allow the front

panel door to open.

If the desired location is closer

than 18" to a magnetic compass, a

trial run should be made with the

unit in operation to be sure that

the compass readings are not

affected.

POWER CONNECTIONS

Twelve volt DC power for the

depth sounder should be supplied

by the boat's 12 volt electrical

system. The power cable

may be

attached to an accessory or power

buss, but if you have problems

with electrical interference, the

cable should be attached directly

to the battery.

If a longer

cable is required, use

ordinary #18 lamp cord available

at any hardware or electrical sup-

ply store. Splices should be

soldered, however, if this isn't

done, then use crimp-type splices.

Tape all splices with electrical

tape.

There are two types

of noise

that can be introduced into the

sonar system if an improper

installation is made, electrical

noise picked up by the transducer

or power cable, and acoustic noise

picked up by the transducer.

Acoustic noise is caused by

water turbulence, air bubbles

FIGURE 2

passing over the transducer, and

cavitation where a partial vacuum

is formed by the flow of water. This

noise is minimized by following

carefully the transducer installation

instructions concerning location of

the transducer.

Electrical noise is caused mainly

by the boat engine's ignition sys-

tem. Keep the transducer cable

and power cable away from possi-

ble sources of electrical inter-

ference. Again, connect the

power

cable directly to the battery if

possible, not the boat's wiring

harness.

Cavitation and electrically

induced noise can be generated if

a careless installation has been

made, but the Suppressor circuit

and Discrimination is effective in

combatting both. Before initial use

or after prolonged storage, better

water-to-transducer contact will be

made if the face of the transducer

is washed with mild detergent and

warm water. Positive contact with

the water is essential to reduce

cavitation noise caused by bub-

bles on the transducer face.

An in-line fuse holder with a 4

amp fuse is supplied with the

X-1 6. Be certain to install this as

close to the

power source (such

as the boat battery or power buss)

as possible. This will protect both

the sonar unit and the

power
