Ratchet

To mount the sonar, slide the unit onto the bracket from above (left). To adjust the view, press and release spring-loaded ratchets while tilting 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 fresh ones. Always remove batteries from the compartment when storing the unit because dead batteries can leak and corrode the contacts.

In cold weather the efficiency of dry cell batteries drops with the tem- perature. 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 batteries over an open flame or direct hot air onto them. A fire or explosion could result.
