Installing The Batteries - Lowrance X-4 Installation And Operation Instructions Manual

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 pow-
er/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.
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.
Install batteries in battery compartment (left).
Attach power cable, and route wires as shown (right).
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
