Mounting the Unit
A quick-release mount is built into the top of the portable power pack. To
attach the unit, first plug in the cable connector. Then, hold the sonar unit
vertically and slide it onto the bracket from above. (The back of the unit
should be touching the front of the bracket as you lower it into position.)
As you push down, the unit will lock into place with a distinct click.
To mount the sonar, slide the unit onto the bracket from above (left).
To adjust the view, press and release spring-loaded ratchets while tilt-
ing the unit (right).
To adjust the viewing angle, pinch the quick-release mount's ratchets
with one hand, then tilt the unit with your other hand. Release the
ratchets and the unit locks into the new position. To remove the unit
from the PPP-12, press the ratchets and lift the unit off the bracket.
Turn the sonar unit on. If it works, turn it off and finish assembling the
portable transducer. If it doesn't work, make sure the battery terminals
are making good contact 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 complaints we
hear about portable units result from stale batteries. Make sure you buy
