Silver Paste on SM Series

Transmitter Thumbscrews

Silver paste is applied to thumbscrew threads on new

units at the factory to improve the electrical connection

from the battery compartment through the housing on

any SM Series transmitter. This applies to the standard

battery door and the battery eliminator.

Threads

provide

electrical

contact

The small enclosed vial contains a tiny amount (25

mg) of silver conductive paste. A small speck of this

paste will improve the conductivity between the battery

cover plate thumbscrew and the case of the SM.

The tiny vial is about

1/2 inch tall and

contains 25 mg of

silver paste.

With improved conductivity (lower resistance) more of

the battery voltage can get to the internal power sup-

plies causing reduced current drain and longer battery

life. Though the amount seems very small, it is enough

for years of use. It is, in fact, 25 times the amount that

we use on the thumbscrews at the factory.

To apply the silver paste, ﬁrst completely remove

the cover plate from the SM housing by backing the

thumbscrew completely out of the case. Use a clean,

soft cloth to clean the threads of the thumbscrew.

NOTE: Do NOT use alcohol or a liquid cleaner.

Simply hold the cloth around the threads and turn the

thumbscrew. Move to a new spot on the cloth and do it

again. Do this until the cloth remains clean. Now, clean

the threads in the case by using a dry cotton swab (Q-

tip) or equivalent. Again, clean the case threads until a

fresh cotton swab comes away clean.

Open the vial, and transfer a pinhead speck of silver

paste to the second thread from the end of the thumb-

screw. A easy way to pickup a speck of paste is to

partially unfold a paper clip and use the end of the wire

to acquire a tiny bit of paste. A toothpick will also work.

An amount that covers the end of the wire is sufﬁcient.

Apply paste to second thread

from end of thumbscrew

It is not necessary to spread the paste more than a

little bit on the thread as the paste will spread itself

every time the thumbscrew is screwed in and out of

the case during battery changes.

Do not apply the paste to any other surfaces. The

cover plate itself can be cleaned with a clean cloth by

rubbing the slightly raised rings on the plate where

it contacts the battery terminal. All you want to do is

to remove any oils or dirt on the rings. Do not abrade

these surfaces with a harsh material such as a pen-

cil eraser, emery paper, etc., as this will remove the

conductive nickel plating and expose the underlying

aluminum, which is a poor contact conductor.
