Information
The Noise Cancel function reduces random noise components
in the transmit and/or receive signal. See page
80
for details.
Simplex channels, 3, 21, 23, 61, 64, 81, 82 and 83 CANNOT
be lawfully used by the general public in U.S.A. waters.
IMPORTANT: To maximize the readability of your transmit-
ted signal, pause a few seconds after pushing [PTT], hold
the microphone 5 to 10 cm (2 to 4 inches) from your mouth
and speak at a normal voice level.
NOTE for the TOT (Time-out Timer) function
The TOT function inhibits continuous transmission beyond a
preset time period after the transmission starts.
10 seconds before transmission is cutoff, a beep sounds to
indicate the transmission will be shut down and “TOT” appears
in the channel name field. Transmission is not possible for 10
seconds after this shut down.
