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.

Two-Wire Microphone Assembly Procedure
The following procedure pertains to a typical two-wire
electret microphone. For non-standard microphones,
contact Lectrosonics Customer Service:
1. Using a pair of scissors or a utility knife, cut a one
inch length from the clear silicon tubing. Ensure the
cuts are clean and square.
2. Cut the cable of your microphone to the length you
prefer (recommended length is approximately 40
inches).
3. Insert the cable through the tubing and then the
plug shell.
Note: If necessary, dip both the cut piece of
silicone tubing and the end of the microphone
cable in alcohol to lubricate them.
4. Strip the outer insulation of the cable back approximately 1/4”.
5. Comb the braid or shield wires to one side and twist
together.
6. Strip the audio wire back approximately 1/8”.
7. Insert the twisted shield wire through the hole in the
strain relief of the plug. Solder and
trim. (See Figure 1.)
8. Solder the audio wire to the plug.
9. Crimp the strain relief over the cable and insulation.
(See Figure 2.)
10. Test the microphone for proper operation and gain.
Strain Relief
Figure 2 - All connections soldered and crimped
Note: It is highly suggested that you test the
microphone before proceeding any further. It will
be much harder to repair connections once the
connector is waterproofed.
11. Screw the plug into the plug cover and tighten. (Put
a broad rubber band around the sleeve of the plug
to protect the sleeve from the needle nose serrations.)
IMPORTANT: At this point, go to the Final
Assembly Procedure on Page 8 to finish the
assembly.

Warning: It is highly suggested that you test
the microphone before proceeding any further.
It will be much harder to repair connections
once the connector is waterproofed. Also,
read “Comments on Three-Wire Microphones”
before proceeding to next step.
Comments On Three Wire Microphones
Three wire microphones cannot be used directly with
the MM series transmitters. They must be slightly
modified to make them act as if they are two wire mics.
Three wire mics have a ground lead, a source (or
audio) lead and a drain (or drain) lead. The source and
the drain refer to connections to a Field Effect Transistor (FET) in the microphone capsule. Either the source
or drain can provide an audio signal. In fact, a two-wire
electret mic is just a three-wire mic with the source
lead removed from the user’s access. For any electret
microphone, the internal FET must have a resistor from
source to ground. Usually, the manufacturer builds this
into the capsule but not always. You may need to add
this resistor. Simply try soldering up the Drain (Bias)
lead to the plug center pin and the Ground (Shield) to
the connector strain relief. If this gives you good mic
level, then use it. If the level is very low or inaudible, add
a 1/8 Watt resistor between the Source (Audio) lead
and ground. We will be happy to mail you a few, if you
can’t find any locally. A good starting value is 1k to 2k
Ohms. The smaller the resistor; the higher the gain. If
you have questions, call Lectrosonics Customer Service
for assistance.

Final Assembly Procedure
This procedure applies to both 2-wire and 3-wire microphones:
1. Locate the tube of RTV and the RTV dispenser
(Part #56113). (It looks like a syringe without a
needle).
2. Replace the light blue cap on the RTV dispenser
with one of the gray nozzles (Part #56114), then
remove the plunger and set it aside.
3. Remove the top of the tube of RTV, reverse it and
pierce the metalic seal at the top of the tube.
4. Squeeze approximately 1/2 inch of RTV from the
tube into the RTV dispenser. Replace the cap on
the tube of RTV and set it aside.
5. Replace the plunger in the RTV dispenser. While
pointing the nozzle upward, gently push the plunger
into the RTV dispenser until any excess air is
squeezed out.
6. Using the RTV dispenser, fill the plug cover with
flowable silicone sealant (see Figure 1) to approximately halfway between the plug strain relief and
the top of the plug cover (1/16” from the top). Allow
the RTV settle for a few minutes and then slide the
tubing down into the plug cover as far as it will go.
Wipe off any excess sealant that may be forced out
of the plug shell with a paper towel.
7. Insert the nozzle of the dispenser deep into the
top of the tubing and fill the tubing with RTV. (See
Figures 2 & 3.)
8. Hang the cable so the connector dangles freely
straight down to cure for at least 8 hours (overnight
is better). This will ensure a watertight bond between the sealant, cable, cover and silicone tubing.
9. Lubricate an
O-ring (Part
#35750) with
a petroleumbased jelly or
white grease
and install in
the groove of
the plug cover.
Do not use a
silicone-based
grease as
silicone oils
Figure 4 - Location O-Ring grove
will attack the
O-ring material. (See Figure 4.)
O-ring groove
Figure 1 - Filling the Plug Cover with RTV
Figure 2 - Injecting the sealant deep into the tubing
Caution: For efficiency, you may be tempted
to install the O-ring at the beginning of this
procedure. DO NOT DO THIS! If you install
the O-Ring before the RTV sealant has the
opportunity to cure thoroughly, you run the
risk of the RTV sealant bonding to the O-ring
since it is also silicone. The O-ring must be
free to move to seal properly.
10. The assembly is now finished and ready for use.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment
needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting cables and then go through the Troubleshooting section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop
attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once
set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment.
There are no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest
flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it does
to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by phone
for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by email or by phone. We need
to know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed
your repair through our receiving and repair departments. The return authorization number must be clearly shown
on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed” for
safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
