Introduction
Watertight Microphone Plug Kit
This manual covers the assembly of the watertight connectors on the microphones for the Lectrosonics waterresistant wireless transmitters. It is very important that
these procedures be followed exactly to ensure a watertight seal at the microphone connector. A good seal will
prevent any moisture from entering the transmitter and
possibly causing corrosion of the internal parts.
CAUTION: If the transmitter is wet (either due
to immersion or high levels of perspiration),
BEFORE opening any covers or connectors,
carefully blot the transmitter dry with a clean
paper towel or cloth. Remove all moisture.
After opening any connector or cover,
carefully blot up any remaining moisture that
may have remained around the seal. THIS IS
IMPORTANT! DO NOT CLOSE ANY COVER
OR CONNECTOR BEFORE MAKING CERTAIN
THERE IS NO MOISTURE IN OR NEAR THE
OPENING. After use, it is important to store
the transmitter in a dry place with all access
doors and connectors opened to allow any
internal humidity to evaporate. Specifically,
open the battery door, the frequency cover
plate and fully unscrew and remove the
microphone connector before storing. Do NOT
store wet and do NOT store sealed. If moisture
is sealed inside the unit it has nowhere to go
other than to chemically react with and destroy
components and the printed circuit board.

Additional Tools and Supplies
You will also need a small soldering iron, needle nose
pliers, good wire cutters and wire strippers. Isopropyl
alcohol or alcohol wipes to clean the parts will be necessary if the parts have become oily or dirty. If the mic
wire is tight in the silicone tubing, a drop of isopropyl
alcohol makes a good lubricant that will evaporate completely after assembly. Ensure that the isopropyl alcohol
you use is clean and does not contain oils. We use a
generic medical grade alcohol that is labeled “Isopropyl
Alcohol 91%” and is certified to be oil free.
