4 BASIC OPERATION VOX function NOTE: An optional headset and optional headset adapter are required for the VOX operation. The VOX function (voice operated transmission) starts transmitting when you speak into the headset's microphone. There is no need to push [PTT]. The IC-M72 automatically returns to receive mode when you stop talking. ➥ Push and hold [ ], then push [H/L•LOCK] to turn the VOX function ON or 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 channel, the VOX function will not be activated. AquaQuake water draining function The IC-M72 uses a new technology to clear water away from the speaker grill: AquaQuake. AquaQuake helps drain water away from the speaker housing (water that might otherwise muffle the sound coming from the speaker). The IC-M72 emits a vibrating noise when this function is being used. ➥ 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 AquaQuake function is activated. And this function won't be activated when an optional speaker-microphone or headset is connected. 12 Channel naming The IC-M72 has a capability to assign up to 10-character channel names or comments for each operating channel, including each 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 names for each VHF marine channel. These defaults can be changed, if desired. You may replace the factory-set opening comment with a comment of your own. The opening comment appears each time the IC-M72 is powered ON. The comment may be up to 16 characters long.

BASIC OPERATION
■
VOX function
The VOX function
(voice operated transmission)
starts transmit-
ting when you speak into the headset
’
s microphone. There is
no need to push
[PTT]
. The IC-M72 automatically returns to
receive mode when you stop talking.
➥
Push and hold
[
]
, then push
[H/L
•
LOCK]
to turn the
VOX function ON or 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.
■
AquaQuake water draining function
The IC-M72 uses a new technology to clear water away from
the speaker grill: AquaQuake. AquaQuake helps drain water
away from the speaker housing
(water that might otherwise muf-
fl
e the sound coming from the speaker)
. The IC-M72 emits a vi-
brating noise when this function is being used.
➥
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 AquaQuake
function is activated. And this function won
’
t be activated when an
optional speaker-microphone or headset is connected.
■
Channel naming
The IC-M72 has a capability to assign up to 10-character
channel names or comments for each operating channel, in-
cluding each weather channel. This provides easy recogni-
tion of channel usage, or station names, etc.
When shipped from the factory, the IC-M72 is programmed
with default names for each VHF marine channel. These de-
faults can be changed, if desired.
You may replace the factory-set opening comment with a
comment of your own. The opening comment appears each
time the IC-M72 is powered ON. The comment may be up to
16 characters long.
