Models: P48W, TM150M
U.S. Patents 7,369,458; 7,961,522; 8,582,393. UK 2 414 077
Follow the precautions below for optimal
product performance and to reduce the risk of
property damage, personal injury, and/or death.
WARNING: Always wear safety glasses, a dust mask,
and ear protection when installing.
WARNING: When the boat is placed in the water,
immediately check for leaks around the screws and
any other holes drilled in the hull.
CAUTION: P48W—Operate at 200kHz only.
Operating at any other frequency will permanently
damage the transducer and/or the echosounder.
CAUTION: TM150M CHIRP transducer—Always
operate the transducer in water. Operating in air will
allow the transducer to overheat resulting in failure.
CAUTION: The bracket protects the sensor from
frontal impact only.
CAUTION: Never pull, carry, or hold the transducer by
its cable; this may sever internal connections.
CAUTION: Never strike the transducer with anything
except the palm of the hand to release it.
CAUTION: Never use solvents. Cleaner, fuel, sealant,
paint and other products may contain solvents that can
damage plastic parts, especially the transducer's face.
IMPORTANT: Read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
