4.2 RECEPTION
1. Turn thePOWER/VOLUME CONTROL knob clockwise to turn the trans-
ceiver on.
2. Turn the SQUELCH CONTROL knob fully counterclockwise. This state
is known as“SquelchOff.”
3. Turn up the POWER/VOLUME CONTROL knob until the noise or audio
from the speaker is at a comfortable level.
4. Select a channel that has no signal being received (no one is transmit-
ting on the channel) and where only noise is heard.
5. Slowly turn theSQUELCH CONTROL knob clockwise and stop immedi-
ately after the noise disappears. This condition is known as the “Squelch
Threshold.” If the knob is turned clockwise past this point, weak signals
may not be received. No noise or no signal is heard until a signal is
received that exceeds the squelch threshold.
6. To change channels, press the [p]or [q]key. Sometimes, a slight ad-
justment of the squelch threshold is needed, as some channels have a
higher noise level than others.
7. Please refer to the Owner’s Manual Supplement for a complete listing of
all USA, International and Canadian VHF Marine channels and their uses.
8. If necessary, press theLAMPkey to turn on thedisplay illumination.The
lamp automatically turns off in about 5 seconds. To turn off the lamp
sooner, press theLAMPkey again.
9. To “lock” the channel so that it is not accidentally changed, hold down
the LAMPkey for about one second. This locks the[p]and [q]buttons
and all the front panel controls except theH/L,PTT andLAMPkeys.The
“” symbol will appear on the display to indicate that the keypad is
locked. Hold down the LAMPkey for about one second to unlock the
keys. The “ ” symbol will disappear from the display..

HX460S Page 11
4.3 TRANSMISSION
1. Perform steps 1 through 7 ofthe RECEPTION discussion above.
2. Before transmitting, monitor the channel and make sure it is clear.
THIS IS AN FCC REQUIREMENT!
3. For communications over short distances, press theH/L key until “ ”is
displayed on the LCD. This indicatesLow power (approximately 1 watt).
NOTE
Transmittingon 1wattprolongs batterylife.Low power(1watt)should
be selected whenever possible.
4. If using Low power is not effective, select Medium power (2.5 watts) or
High power (5 watts) by pressing theH/L key until “ ” (Medium power)
or “ ” (High power) is displayed.
5. When receiving a signal, wait until theincoming signalstopsbeforetrans-
mitting. The transceiver cannot transmit and receive simultaneously.
6. Press the PTT (Push-To-Talk) switch to transmit. The “TX” indicator is
displayed during transmission.
7. Speak slowly and clearly into the microphone. Hold the microphone about
½ to 1 inch away from your mouth.
8. When the transmission is finished, release thePTT switch.
9. Refer to the OWNWER’S MANUAL SUPPLEMENT for an overview of
commontransceiver operating procedures.
4.4 TRANSMIT TIME - OUT TIMER (TOT)
While thePTT switch is held down, transmission time is limited to 5 minutes.
This prevents prolonged (unintentional)transmissions. About 10 seconds
before automatic transmitter shutdown, a warning beep sounds from the
speaker. The transceiver automatically switches to the receiving mode, even
if the PTT switch is held down. Before transmitting again, the PTT switch
must first be released,thenpressed again. ThisTime-Out Timer(TOT)pre-
vents a continuous transmission that would result from an accidentally stuck
PTTswitch.

4.5 USA, CANADIAN, AND INTERNATIONAL BANDS
1. To change theoperating band (channel set) of the transceiver,hold down
the 16/9 key and press the WX key. The band will change from USA, to
International, and to Canadian with each press.
2. “USA” appears on the LCD for the USA band, “CAN” appears for the
Canadian band, and “INTL” appears for the International band.
3. Refer tothe marine channel charts in the OWNER’S MANUAL SUPPLE-
MENT for allocated channels in each band.
4.6 NOAA WEATHER CHANNELS
1. To receive a NOAA weather channel, press theWX key. The transceiver
changes to the weather channel mode. This mode consists of a special
pre-set memory bank containing the standard NOAA weather channels.
2. Thetransceiverwillbesettothelast-usedNOAAweatherchannel. Press
the [p]or [q]key to change to other weather channels.
3. To exit from the weather channelmode, press the WX key. The trans-
ceiver will revert to the channel you were using prior to switching to the
weather channel mode.
4.7SCAN
This transceiver provides a special “Scanning Memory Bank” which allows
you to designate certain channels for inclusion in a “loop” which will be
scanned at high speed. If an incoming signal is detected on one of the chan-
nels in the scanning loop, the radio will pause on that channel, allowing you
to listen to the incoming transmission.
1. Select the desired channel to be included in the scanning loop using the
[p]or [q]key.
2. Press the MEM key to store the channel into the transceiver’s scanning
memory. “MEM” will be displayed on the LCD.
3. Repeat steps 1 and 2 for all the channels to be scanned.
4. To delete a channel from the transceiver’s scan memory, press theMEM
key again while the memorized channel is displayed. “MEM” will disap-
pear from the display.
5. All channels programmed remain in the transceiver’s scan memory even
if the power is turned off. See section 4.17: “RESETTING THE
TRANSCEIVER’S MICROPROCESSOR” to clear all channels from the
transceiver’s scan memory.

HX460S Page 13
6. Adjust the SQUELCH CONTROL knob until background noise is elimi-
nated.
7. To start scanning, press the SCAN key. The scan proceeds from the
lowest to the highest programmed channel number and stops on chan-
nels when a transmission is received. Scanning will resume when the
squelch closes after the incoming signal disappears at the end of the
transmission.
8. To stop the scan, press theSCAN key.
4.8 PRIORITY SCAN
The priority scanning feature allows the radio to scan while also keeping
watch on a particularly important “priority channel.” The following channels
can be set as the priority channel: 16, 09, and Preset Channels A through E
(Preset Channels are describedin section 4.14).
1. To set the priority channel, hold down the 16/9 key and press the MEM
key. The channel will change from 16 to 09 to Preset A to Preset B to
Preset C to Preset D to Preset E with each press of theMEM key. The
displayed channel will be set as the priority channel.
2. For priority scanning, hold down theSCAN key during normal scanning.
Scanning will proceed between the memorized channels and the priority
channel. The priority channel will be scanned after each programmed
channel. A “P” is shown on the left side of the channel number during
priority scanning.
3. As an example of priority scanning, let us say that channels 06, 07, and
08 are memorized in the transceiver’s scan memory. Priority scanning
will proceed in the following sequence:
[CH06]à[Priority Channel]à[CH07]à[Priority Channel]à
[CH08]à[Priority Channel]à[CH06]à[Priority Channel]……
4. Evenwhenthetransceiverstopsandlistenstothesignalofaprogrammed
channel, the transceiver will shift to a “dual watch” mode between this
channel and the priority channel. Therefore, your priority watching of the
designated channel is not compromised when the scanner has paused
on an active channel.

HX460SPage 14
4.9 NOAA WEATHER ALERT
In the event of extreme weather disturbances such as storms and hurri-
canes, NOAA (National Oceanic and Atmospheric Administration) sends a
“weather alert” consisting of a 1050 Hz tone, followed by weather reports on
the weather channels. The transceiver is capable of receiving this alert if the
followingisperformed:
1. Program your area’s weather channels into the transceiver’s scan
memory. Follow the same procedure as for regular channels under Sec-
tion 4.7.
2. Press the SCAN key to start the scan.
3. The memorized weather channels are scanned along with the regular
memorized channels. Scanning will not stop, however, on the (continu-
ous) weather broadcast channels unless the weather alert tone is re-
ceived.
4. When an alert is received on a weather channel, scanning stops and the
transceiver emits a beeping tone that will stay on for 5 minutes or until
the user presses the WX key to listen to the Weather Alert.
4.10 EMERGENCY CHANNEL 16
1. To select the emergency channel, press the16/9 key from any channel.
2. If you cannot contact anyone on channel 16, switch to another channel.
3. See the OWNER’S MANUAL SUPPLEMENT for additional emergency
operatingpractices.
4. To recall the previously-used channel when you are finished on channel
16, press the 16/9 key again.
4.11 CHANNEL 9
Channel 9 is used as a hailing channel for initial, non-emergency contacts
with other vessels. Hold down the16/9 key for 1 second to select channel 9.
You should shift to a different channel, by mutual agreement with the other
vessel’s operator, after contact is established (so as to keep the hailing chan-
nel clear for other users).

HX460S Page 15
4.12 OPERATING ON CHANNEL 13
Channel 13 is used at docks, bridges and for maneuvering in port. Mes-
sages on this channel must concern navigation only, such as meeting and
passing in restricted waters. In emergencies and when approaching blind
river bends, high power is allowed. Holding down the H/L key will change
the power output from 1 Watt ( ) to 5 Watts( ); if pressed and held again
2.5 Watts ( ) will be selected. When thePTT switch is released, the trans-
ceiver will revert to low power. Press and hold in the H/L key again if you
need High power on a subsequent transmission.
4.13 OPERATING ON CHANNEL 67
When channel 67 is used for navigational bridge-to-bridge traffic between
ships, High or Medium power may be used temporarily (in the USA band) by
pressing the H/L key. When the PTT switch released, the transceiver will
revert to low power.
4.14 PRESET CHANNELS (A ~ E): INSTANT ACCESS
Five user-assigned channels can be programmed for instant access. Press-
ing the PRESET key provides activates the user-assigned channel bank. If
the PRESET key is pressed andno channels have been assigned, an alert
beep will be emitted twice from the speaker.
4.14.1Programming
Hold down the PRESET key, and press the [p]or [q]key (repeatedly, if
necessary) until the desired channel number (from among the regular oper-
ating channels) is displayed.
With the desired channel number displayed, release thePRESET key. The
“A” notation will appear on the LCD display, indicating that the displayed
channel is now saved in the Preset Channel A position.
Repeat steps 1 and 2 to program the desired channels into Preset Channels
b~ E.
To delete a Preset Channel, hold down thePRESET key and press the[p]
or [q]key until the Preset Channel number to be deleted is displayed, then
release thePRESET key.

HX460SPage 16
4.14.2Operation
Pressing the PRESET key toggles between Preset Channel A, b, C, d, E,
and the last selected “regular” channel. Preset Channel A is represented by
“A” to the left of the channel number on the LCD, and channel B is repre-
sented by “b,” and so forth. The letter “A” should not be confused with the
“A” that sometimes is displayed to therightofthechannelnumber(described
in the section 3.2 of this Owner’s Manual).
4.15 SIMPLEX/DUPLEX CHANNEL USE
All channels are factory-programmed in accordance with FCC (USA), In-
dustry Canada and International regulations. The mode of operation cannot
be altered from simplex to duplex or vice-versa. Simplex or duplex mode is
automatically activated, depending on the channel and whether the USA,
International or Canadian operating band is selected. Refer to the channel
charts in the OWNER’S MANUAL SUPPLEMENT.

4.16 BAROMETRIC PRESSURE METER
TheoptionalBarometricPressureunit(SU-1)bringstotheHX460S theunique
capability of providing readout of the current barometric pressure. TheSU-1
unit requires calibration of the ‘offset’ parameters, so that the pressure reading
will be correct. To do this you must have a barometer to use as a reference as
you adjust the SU-1 to match its reading; see section 4.17.6 boF (Barometric
Pressure Offset). The SU-1 Barometric Pressure Unit can be installed in the
transceiver by referring to the following illustration:
SU-1 Operation
1. Set the SQUELCHCONTROL knob to the “Squelch Threshold” point.
2. Hold down the H/L key for at least 1 second; this initiates measurement
of the current Barometric Pressure.
3. After few seconds, the current Barometric Pressure (in mm of Hg) will
appear on the display.
4. To return to normal operation, again hold down the H/L key until the
HX460 shows the last selected working channel; alternatively, turn the
squelch counter-clockwise until noise is heard. The display will revert to
the last channel selected. Return the squelch control to the “threshold”
position to resume normal operation.
Installation of the SU-1
1. Make sure that the transceiver is off. Remove the hard or soft case, if
used.Remove the battery pack.
2. Locate the connector for the SU-1 under the caution seal in the battery
compartment on the back of the radio, just peel off the caution seal.
3. Align the connector on the SU-1 with the transceiver’s connector
and gently press the unit into place.
4. Affix the new (supplied with theSU-1) caution seal, and replace the
battery. Installation is now complete.
