Mounting the Unit

To use a portable power pack, you install the batteries and then attach the sonar unit to the power pack's bracket. Plug in the power/transducer cable and you're ready to fish. The PPP-12 has a quick-release mounting bracket built into the case.

Installing the Batteries

Open the case and lay it flat. (The latch is located below the handle.) Insert eight "AA" size batteries into the battery adapter and place it in the battery compartment. Slip the battery cover tabs into the slots in the case wall, then close the battery cover with the thumb screw.

Install batteries in battery compartment (left).

Attach power cable, and route wires as shown (right).

Plug the cable's power (dog bone-shaped) connector into the socket on the battery compartment cover. Route the cable's unit connector and about 6 inches (15.2 cm) of cable through the opening under the sonar mount. Close the case bottom, using the slot in the case wall to avoid pinching the cable. Turn the unit over to mount the sonar.

CAUTION:

When using the sonar in a saltwater environment, we strongly recommend that you unplug the power connector from the bat- tery socket when the unit is not in use. When the unit is turned off but still connected to a power supply, electrolysis can occur in the power cable plug. This may result in corrosion of the plug body along with the electrical contacts in the cable and the unit's power socket.

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.
