Portable Sonar Installation
Like many Lowrance products, the M52 Pro sonar is capable of portable
operation. It uses the optional PPP-12 portable power pack.
The power pack and portable transducers expand the uses for your so-
nar. An alternative to the PPP-12 is the PPP-15 portable power pack,
which was designed especially for ice fishing. It includes a rechargeable
gel cell battery and a transducer designed for stationary use.
The PPP-12 package includes the power pack, battery adapter and a port-
able transducer. The transducer can be stored inside the power pack. The
PPP-12 requires eight AA alkaline batteries. Batteries are not included.
Installing the Batteries
Release the latch on the front of the power pack case. Open the com-
partment and install eight AA batteries into the adapter. For the long-
est life, we recommend you use alkaline batteries.
After installing the batteries, plug the cable's power connector into the
socket on the battery compartment cover. Route the cable's unit con-
nector and about 6 inches of cable through the opening under the sonar
mount. Close the cover, plug the connector into the sonar unit and
mount the unit on the built-in bracket.
In cold weather the efficiency of dry cell batteries drops with the tem-
perature. We find it a good idea to have the sonar unit good and warm
along with the batteries before we leave home.
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.
