BASIC OPERATION
IMPORTANT: To maximize the readability of your transmit-
ted signal, pause a few sec. after pushing [PTT], hold the
microphone 5 to 10 cm (2 to 4 inches) from your mouth
and speak into the microphone at a normal voice level.
NOTE: The transceiver has a power save function to
conserve the battery power. The power save function acti-
vates automatically when no signal is received for 5 sec.
To prevent accidental prolonged transmission, etc., the
IC-M90 has a time-out timer function. This timer cuts a
transmission OFF after 5 min. of continuous transmission.
