■
VOX function
The VOX function
(voice operated transmission)
starts transmis-
sion without pushing
[PTT]
when you speak into microphone;
then automatically returns to receive when you stop speak-
ing
(hands-free operation becomes possible)
.
➥
Push and hold
[
]
, then push
[H/L•LOCK]
to turn the
VOX function ON/OFF while connecting the headset and
optional headset adapter to
[SP MIC]
connector.
• “VOX” appears on the LCD while the VOX function turns ON.
• The VOX gain and VOX delay can be set on the SET mode. (p. 22)
• During scan, dual/tri-watch or on a transmission inhibited chan-
nel, the VOX function will not be activated.
■
Water draining function
IC-M72 is employs a new water draining support system for
driving out water that has built up in the speaker housing. A vi-
brating noise occurs when this function is being used. This
new feature keeps the speaker and speaker housing free
from water and grit build up for crisp, clear audio all the time.
➥
Push and hold both
[16•9]
and
[H/L•LOCK]
.
• A low beep tone sounds for 9 sec. to drain water, regardless of
[VOL]
control setting.
• The transceiver never accepts a key operation while the water
draining function is activated. And this function won’t be activated
when an optional speaker-microphone or headset is connected.
■
Comment programming
The IC-M72 has a capability to assign up to 10-character
channel comments for each operating channel including the
weather channel. This provides easy recognition of channel
usage, or station names, etc.
When shipped from the factory, the IC-M72 is programmed
with default comments for each VHF marine channel. These
defaults can be overwritten if desired.
In addition, up to 16-character user-programmable opening
comments are also available.
