NEVER immerse the connector in water. If the connector be-
comes wet, be sure to dry 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. 5 to 10 cm (2 to 4 inches)
from your mouth, and speak in a normal voice level.

below. Be careful not to cross thread the connection.

CAUTION: Attach the speaker-microphone's
connector securely to prevent accidental
dropping, or water intrusion in the connector.
IMPORTANT: KEEP the transceiver's [SP MIC] connec-
tor cap attached when the speaker-microphone is not
in use. Water will not get into the transceiver even if the
cover is not attached, however, the terminals (pins) will
become rusty, or the transceiver will function abnormally
if the connector has become wet.
