Airmar PM260—Pocket or Keel-Mount - Manual

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 goggles and a dust
mask when installing.
WARNING: Immediately check for leaks when the
boat is placed in the water. Do not leave the boat
unchecked for more than three hours. Even a small
leak may allow considerable water to accumulate.
CAUTION: CHIRP transducer—Do not install in the
engine compartment or other hot place. The
transducer may fail if it overheats.
CAUTION: CHIRP transducer—Always operate the
transducer in water. Operating in air will allow the
transducer to overheat resulting in failure.
CAUTION: The transducer must be flush with the
bottom of the hull for good performance. Dry fit the
transducer in the pocket before installing.
CAUTION: Never install a metal housing on a vessel
with a positive ground system.
CAUTION: Never mount a bronze transducer in a
metal hull, because electrolytic corrosion will occur.
CAUTION: Never pull, carry, or hold the transducer by
the cable. This may sever internal connections.
CAUTION: Never strike the transducer.
CAUTION: Never use solvents. Cleaners, fuel, sealant,
paint and other products may contain solvents that can
damage plastic parts, especially the transducer’s face.
IMPORTANT: Please read the instructions completely
before proceeding with the installation. These
instructions supersede any other instructions in your
instrument manual if they differ.
