NEVER immerse the connector in water. If the connector be-
comes wet, be sure to dry it BEFORE attaching it to the trans-
ceiver.
NOTE: The microphone is located at the top of the
speaker-microphone, as shown in the diagram above. To
maximize the readability of your transmitted signal
(voice),
hold the microphone approx. 2.5 cm
(1 inch) from your
mouth, and speak in a normal voice level.

tor and carefully screw it tight, as shown in the diagram

cap attached when the speaker-microphone is not in use.
