against the battery contacts. Also make sure the batteries are oriented
correctly in the battery adapter.
If it still doesn't work, check the battery voltage. Most of the complaints
we hear about portable units result from stale batteries. Make sure you
buy fresh ones.
In cold weather the efficiency of dry cell batteries drops with the
temperature. We find it a good idea to have the batteries and the sonar
unit good and warm before we leave home.
If the batteries do lose a charge, you can sometimes restore them by
placing them in a warm room or car interior. A better way is to replace
them with batteries that have been kept warm.
WARNING:
Never heat the batteries over an open flame or direct hot
air onto them. A fire or explosion could result.
Portable Transducer Assembly
Recommended tools for installation include a slotted screw driver and
two adjustable wrenches.
Assemble the transducer and bracket as shown in the following figure.
Attach the transducer to the bracket with the supplied hardware.
Make sure there is one washer on each side of the transducer, inside
the bracket. Slide the other washer over the end of the bolt and thread
the nut onto it.
Screw the suction cup onto the bracket using the supplied screw and flat
washer. Tie the nylon cord through the hole in the top of the bracket.
When using this transducer, tie the other end of the nylon cord to the boat.
This will help prevent the loss of the transducer if it comes off the boat.
