1 INTRODUCTION
Congratulations on choosing Ocean! Your handheld marine transceiver
was designed as a high-quality, robust, and reliable marine radio, using
the latest technology available. Ocean ensures secure transmission and
reception on all VHF marine channels, as required by the Internatio-
nal Telecommunications Union (ITU). Your transceiver is composed of
the highest-quality electronic components, conforms to EN 301 178-
2, CE/99/05 regulations, and is water resistant (splashproof), ensuring
clear, reliable communication for many years. Ocean is equipped with
a microprocessor, which controls not only the marine band tuning, but
also many advanced functions such as Dual Watch and memory chan-
nels. The following are the principal features of your transceiver:
• PLL (Phase Locked Loop) synthesizer circuit – for precise and
stable channel selection.
• Large, back-lit LCD display – constantly displays Ocean’s parame-
ters and settings. The backlighting enables you to view the screen in
case of little environmental light.
• Automatic squelch– while in standby, this function automatically
eliminates bothersome background noise.
• Automatic Power Saver – saves energy when in standby, prolon-
ging battery life.
• Recall button for Channel 16 – for instant access to channel 16 (the
universal marine channel for emergency contact).
• Channel scanning – automatically searches for marine band chan-
nel signals.
• Dual Watch – for monitoring of radio traffic on two channels simul-
taneously.
• VOX (Voice Operated eXchange) – activates transmission when
the user begins speaking. When used with optional microphone ac-
cessories, this feature enables the user to operate hands-free, clip-
ping the transceiver to a belt.
• Call button – briefly sends the transceiver into transmission mode,
generating audio call tones.
• Clock and chronometer – enables the user to view the current time
on the LCD display and to use the transceiver as a chronometer that
is precise to the hundredths of a second.
• High/low power selection – reduces transmission power in short-
distance communication, allowing Ocean to save energy and redu-
cing the risk of interference.
• Multifunctional bar indicator– in reception mode, this function in-
dicates the incoming signal strength using a series of bars. In tran-
smission mode, it indicates the output power.
• Battery level indicator – constantly displays the battery level.
• Keypad lock – locks the transceiver keypad to avoid the accidental
activation of buttons or settings.
• 20 memories – for storing, rapid recall, and scanning of your 20
most-used channels.
• Power is supplied through 4 normal AA batteries – the (optional)
batteries can be either rechargeable or alkaline, for maximum flexibi-
lity of use and operating cost.
• Sockets for speaker, microphone, and battery charger (SPK,
MIC CHG) – these sockets enable the use of various microphone
accessories (headphone, microphone/speaker, etc), as well as the
use of an optional standard “MW904” wall battery charger.
• 20 private channels – using the optional PRG-OCEAN program,
you can program 20 channels within the VHF marine band.
The manufacturer, with its effort to constantly improve product quality,
reserve the right to change characteristics and features without prior
notice.

2 ABOVE ALL… SAFETY!
2.1 Symbols used
For ease and convenience of use, this manual uses symbols to highlight
urgent situations, practical advice, and general information.
Symbols such as this one indicate a crucial description regar-
ding technical repairs, dangerous conditions, safety warnings,
advice, and/or other important information. Ignoring these sym-
bols may result in serious problems and/or damage and/or per-
sonal injury.
Notes such as this one indicate practical advice that Midland
suggests be followed for the optimal performance of Ocean.
Important sentences and words have been underlined.
2.2 Warnings
2.2.a General
Before using the transceiver, carefully read all the instructions
contained in this manual in the order in which they are written.
Cross-references to paragraphs and chapters are provided for
ease of use only. After reading, keep this manual for future refe-
rence.
Read and follow all the warning and instruction labels found on
the radio and its accessories.
Always observe laws and regulations regarding the use of ma-
rine transceivers, which may change according to the country
you are in. Where prohibited, or in areas where the radio may
cause interference or danger, turn off your radio.
Do not transmit without an antenna connected – although the
radio is protected, this may seriously damage its R.F. power sta-
ges. Do not use your transceiver if the antenna is damaged.
Keep the antenna at least 2.5cm from your head and body during
transmission, and keep a distance from other electrical devices.
Your transceiver contains a radio transmitter. Be aware that,
when you press the PTT button, the radio emits radio frequency
(RF) energy. If you use cardiac stimulators, hearing aids, or other
medical devices, consult your physician or the manufacturer of
the device to ensure the device is adequately protected from RF
energy. Your physician will be able to suggest ways of obtaining
this information.
Keep a tight grip your radio (a fall may damage it) and ensure the
PTT button is not pressed accidentally when you do not need to
transmit. Do not hold the transceiver by the antenna! This is a
delicate part of the device and is vital for the proper functioning
of the radio.
Pay attention to environmental conditions – although Ocean
was designed to operate under the most severe conditions, it
is important to avoid exposure to environments that are exces-
sively humid or dusty, or to temperatures outside the -15 to
+55°C° range. Also avoid exposure to direct sunlight, jarring,
and excessive vibration.
Before using the radio, ensure that all protective covers and
parts are in perfect operating condition, in order to ensure ma-
ximum protection against humidity and atmospheric agents.
Although this radio was designed to be water resistant, avoid
getting it wet as much as possible and do not let any liquids fall
on it. If the transceiver or one of the accessories gets wet, dry it
off as soon as possible with a soft, clean cloth. If you feel that li-

5
ENGLISH
quid may have penetrated the radio’s housing, contact a service
centre for a diagnostic check.
Do not use the radio, its accessories, and/or substitute the bat-
teries in potentially explosive environments. A single spark may
cause an explosion.
Do not open the radio for any reason! Ocean’s precision mecha-
nics and electronics require experience and specialized equi-
pment; for the same reason, the radio should under no circu-
mstances be realigned as it has already been calibrated for
maximum performance. Unauthorized opening of the transcei-
ver will void the warranty.
Use original accessories only; otherwise you may seriously da-
mage your handheld transceiver.
Turn off the radio before cleaning it. For further information, re-
fer to Chapter 7.
2.2.b Batteries
Before using the battery charger, carefully read all notes and
cautions regarding this equipment.
Do not short-circuit the battery terminals: doing so may result in
fire, burns, or explosions.
Never throw batteries into a fire or expose them to high tempe-
ratures; doing so may cause fires or explosions. Always follow
the regulations set out by your country of residence.
Use only the original batteries and battery charger. Use of unap-
proved accessories may cause burns, fires, or explosions, and
may create serious damage to the radio/batteries or to people.
The battery charger should only be used indoors.
Ensure your power supply conforms to the one required for your
battery charger (AC adaptor). If you are unsure, check with your
vendor or your local electricity supplier.
To avoid damaging the power cord to your battery charger,
connect it in a place where it will not be stepped on and where
nothing will be placed on top of it. Insert the prongs into a soc-
ket that has been grounded.
Avoid shocks and excessive vibrations. Do not use the battery
charger if it has been subjected to strong shock, had a fall, or
appears damaged; immediately contact an authorized service
centre.
Do not dismount the battery charger. Any repair work must be
performed exclusively by authorized service centers. For further
information, contact your local supplier.
To reduce the risk of electrical shocks, disconnect the power ca-
ble before performing cleaning or maintenance. Grasp the plug
(not the cord!) when removing it from the socket. Use of inap-
propriate extension cords may cause fire or electrical shocks.
Do not expose the batteries directly to temperatures outside the
-20°C to +35°C range during storage and do not charge them in
temperatures outside the +5 to +55°C range.
2.3 Assistance
We advise you to write the serial number of your transceiver in the
space provided below. This number is found on the rear panel of the
transceiver and will be useful in the event of repair/assistance and/or
loss and/or theft.

4 PREPARATION
Before using your transceiver, ensure that your package contains:
• The transceiver
• The flexible, rubber ducky antenna with SMA connector
• The belt clip
• The user’s manual (this manual)
If any part is missing or damaged, contact your supplier as soon as
possible.
In order for the device to function, you will require four AA batteries,
either 1.2V NiMH rechargeable or 1.5V non-rechargeable alkaline.
For further details, refer to par 4.3.
To charge the NiMH batteries without taking them out of the radio,
a standard MW904 wall charger is available, as well as a CA445
intelligent table-top charger. For further details, refer to par. 4.4.
4.1 Connecting/removing the antenna
4.1.a Connecting the antenna:
1) Hold the transceiver in one hand, with the antenna connector fa-
cing upwards; pick up the flexible, rubber ducky antenna by its
base (the larger end, with the SMA connector).
2) Orientate the base of the antenna in the direction of the transcei-
ver’s antenna connector.
3) Screw the antenna into the antenna connector, turning it clockwise
until it is firmly in place.
Do not tight too much the antenna: doing so may damage the
threaded connector on the radio or the antenna itself.
4.1.b Removing the antenna:
1) Follow step 1 of paragraph 4.1.a.
2) Unscrew the flexible, rubber ducky antenna, turning it counter-
clockwise and removing it.
Avoid transmitting without the antenna connected or with a
damaged antenna. Although the radio is protected, doing so
may seriously damage the R.F. power stages. Use the radio
only with the antenna.
4.2 Fastening/removing the belt clip
The rear belt clip allows the user to easily clip the transceiver to a belt.
However, it may be necessary to remove the clip in order to make
easier the radio maintenance or battery substitution. To fasten the clip
to the radio, position it above the groove found of the back of the
transceiver, then drag it downwards until it locks into place. To remove
the clip from the belt, lift the release lever and drag the clip upwards
until it comes free.
Ensure the belt clip is correctly attached; otherwise the tran-
sceiver may become unattached accidentally and fall.
4.3 Installing/removing the batteries
The transceiver operates with four AA batteries (not included). There
are two battery options available:
• Rechargeable 1.2V NiMH – available in various capacities (in mAh).
Higher battery capacity allows for greater duty, but requires longer
recharging time.
• Non-rechargeable 1.5V alkaline.

10
ENGLISH
For installing/removing the batteries, it is not necessary to remove
the belt clip (procedure outlined in par. 4.2), however, this does
make it easier to access the batteries.
Do not install a combination of rechargeable and alkaline bat-
teries in your transceiver. Always use 4 AA batteries of the
same type, brand, and from the same stock. Always use the
same batteries as a set in order to ensure their level of charge
is the same.
If you are not using the transceiver for an extended period, re-
move the batteries.
4.3.a To install the batteries:
1) Carefully unhook the rear
clasp by slightly raising it and
catching the depression with
a fingernail, then rotating the
clasp downwards.
2) Carefully lift the rear protec-
tive cover from the battery
compartment and remove it.
3) Insert the batteries (rechargeable or alkaline) in the battery com-
partment, ensuring the batteries are correctly oriented in their pola-
rity, as indicated on the inside of the battery compartment.
4) Carefully insert the cover’s tabs into the slots at the top of the bat-
tery compartment, and then slowly press the cover down against
the battery compartment until it is perfectly aligned with the tran-
sceiver body.
5) Carefully return the clasp onto the protective cover, pressing until it
clicks into place.
Ensure you have properly closed the battery compartment co-
ver.
4.3.b To remove the batteries:
1) Follow steps 1 and 2 of paragraph 4.3.a.
2) Remove the batteries from the radio.
3) Follow steps 4 and 5 of paragraph 4.3.a.
4.4 Recharging the batteries
Two types of battery chargers are available. Each one is able to charge
NiMH batteries without removing them from the radio:
• Standard MW904 wall battery charger – this is the least expensive.
It supplies a slow charge, allowing for maximum battery life. For
further details, refer to par. 4.4.a.
• CA445 intelligent table-top battery charger – for rapid charging and
greater flexibility of use. It also monitors the charge, and once bat-
teries are charged, switches to trickle charging. For further details,
refer to par. 4.4.b.
New batteries do not immediately allow for maximum duty, as they
must be “run in” through at least 3 complete cycles of charge/
discharge.
Use the battery charger only if you have installed four rechar-
geable NiMH batteries. Never attempt to charge other types
of batteries (particularly alkaline) – doing so may cause explo-
sions or personal harm.
Read the battery usage warnings outlined in par. 2.2.

11
ENGLISH
4.4.a Standard MW904 wall battery charger
1) Ensure the radio is turned off (it must remain off for
the entire period of charging).
2) Carefully lift the rubber flap on the right side of the
transceiver, slipping a fingernail into the center left
part, and rotating it towards the right, as indicated
in the figure.
3) Insert the plug at the end of the MW904 battery
charger cable into the MIC CHG socket, then con-
nect the battery charger to an AC power source.
4) Once the batteries are charged (see table below for charging ti-
mes), disconnect the battery charger from the AC power source,
then disconnect the transceiver from the battery charger.
5) Return the rubber flap to its place.
TABLE OF APPROXIMATE TIMES FOR COMPLETE RECHARGE,
ACCORDING TO THE BATTERY TYPE USED.
Code Battery capacity (mAh) Time (hours)
C734 2.300 15.5
C697 1.700 11.5
C696 1.200 8
Do not overcharge the batteries! When the batteries are com-
pletely charged, the charging process does not stop automati-
cally. Do not forget to disconnect the transceiver from the bat-
tery charger as soon as possible after charging is complete,
otherwise you may seriously damage the batteries and/or the
transceiver.
For successive charging, longer duty, and battery life, refer to
par. 4.5.
Do not forget to replace the rubber flap after charging.
4.4.b CA445 Intelligent, table-top battery charger
This battery charger is able to rapidly charge batteries and to detect
when the charging is complete, switching automatically the trickle
charge.
1) Insert the transceiver, with the charging contacts facing downwar-
ds, into the CA445 battery charger slot, then connect the battery
charger to an AC power source. Charging will begin, and an LED
indicator will light up.
2) Once charging is complete, a green LED light will appear on the
battery charger, indicating the operation is complete and the devi-
ce has switched the trickle charge.
3) When possible and for increased security, remove the transceiver
from the charging slot and disconnect the battery charger from the
AC power source.
For successive charging, longer duty, and battery life, refer to
par. 4.5.
4.5 Proper use of rechargeable batteries
When possible, recharge batteries only when at least two of the icon
bars have disappeared (the icon should indicate ). Be aware that
charging time will be shorter in proportion to the amount of residual
charge remaining in the battery, therefore, when only two bars appear
in the icon, this indicates you will require about 50% of time indicated
on the table in par. 4.4.a. This is particularly important if you use the

12
ENGLISH
MW904 standard charger, otherwise you risk overcharging the batte-
ries.
If you use the batteries properly, you will obtain at least 400 cycles
of charge/discharge at maximum duty. It is normal for battery duty to
gradually decrease after about 2/3 of the battery’s life.
Rechargeable battery packs lose their charge over time even if
they are not used (auto-discharge); this is normal. A NiMH (Nickel
Metal Hydrate) battery may lose 10 – 20% of its energy within a few
days.
4.5.a Memory effect
Rechargeable NiMH (Nickel-Metal-Hydrate) batteries are virtually unaf-
fected by the “memory effect”. This phenomenon is associated with a
drastic reduction of battery autonomy and is triggered if the batteries
are regularly charged before having lost at least 50-75% of their power
and/or are not completely recharged. To avoid the memory effect:
• When possible, recharge the batteries only when they are comple-
tely discharged; i.e. when the battery indicator will be flashing.
• Do not disconnect the battery charger before the time indicated for
complete battery charging.
• Discharge and recharge your batteries completely at least twice a
month.
In any case, the best solution for avoiding the memory effect is to use
in turn two battery sets: one in use, and the other being charged as
spare set.
The memory effect can be easily eliminated by completely charging/
discharging the batteries 3 or 4 times.
The memory effect should not be confused with the normal
battery life, which is 400 cycles of charge/discharge on average.
It is completely normal for operating duty to decrease when the
batteries have reached the end of their life; at this point, you will
need to substitute the battery set.

5 STANDARD FUNCTIONS
5.1 Turning Ocean on/off
To turn on the transceiver, turn the ON/OFF/VOLUME knob clockwise
until it clicks on: the LCD display will come on, and you will hear a
beep (acoustic signal).
The LCD display backlighting will automatically turn off after approx.
10 seconds in order to save energy, though the display itself will
remain active.
To turn off the transceiver, turn the knob counter-clockwise until you
hear another click.
5.2 Volume regulation
Bring the ON/OFF/VOLUME knob to medium. Once the transceiver
receives a signal, adjust the volume to a comfortable level. If no signal
is received, use the button as described in par. 5.5.
5.3 Selecting a channel
Press the or buttons respectively to scroll up or down through
the marine channels until finding the desired channel. To scroll quickly
through the channels, hold down the or button until you reach
the desired channel.
The marine band does not include some channel numbers. Refer
to the frequency table in Chapter 11. Furthermore, channels may
have a frequency reception that is different from the transmission
one (duplex channels) or it is the same (simplex channels). Normally,
communication between vessels can only take place on simplex
channels.
Your transceiver is preset on international channels. Depen-
ding on the country you are in, it is your responsibility to select
INT or USA channels, depending on the local regulations in or-
der to avoid interference. For further details, refer to par. 6.4.
5.4 Transmission and reception
During transmission and reception, ensure the antenna is as vertical
as possible and is free from obstacles in the direction of your
party.
5.4.a Reception
When the PTT is not pressed, the radio is in reception and is ready
to receive incoming communication on the currently tuned channel
(stand-by). If you are not receiving communications in stand-by and
have not activated any commands for at least 10 seconds, the display
will flash Power Saver, indicating that the power saver function has
been automatically activated. The radio will remain ready to receive
signals. In this case:
• The BUSY icon will appear on the display, along with the icon,
which indicates the strength of the incoming signal (the number of
bars being proportional to the strength of the signal).
• The device which silences the audio in the absence of signals
(squelch) will automatically disable. If reception happens to be bro-
ken, try to use the monitor function as described in par. 5.5.
5.4.b Transmission
The PTT (push to talk) button is located on the top left of your Ocean.
To transmit:

14
ENGLISH
1) Ensure the channel you’ve selected is not a reception-only channel
(if it is, the transmission will be disabled) and that no one else is
talking (this will appear on your display as the BUSY icon).
2) Hold down the PTT button: will appear on the display, and the
icon will indicate your relative transmission power (the number
of bars is proportional to your relative transmission power).
3) Wait a second, then speak in a normal voice, facing the transcei-
ver’s microphone at a distance of approx. 5 cm.
4) When you have completed your message, release the PTT button:
and will disappear from the display and the transceiver will
return to reception mode.
Obviously, you can only communicate with stations that are tuned
on the same channel.
If the BUSY icon appears on the display, but you don’t hear
anything, you may have accidentally turned the volume to the
minimum level.
5.5 Monitor function
The (Monitor) button is for temporarily excluding (opening) the
circuit which silences the receiver in the absence of signals (squelch)
in order to listen for extremely weak signals that can’t open the squel-
ch stably. In this mode, you avoid listening to broken communication.
To activate the monitor function, hold down the button until you
hear background noise (or else a weak signal). Release the but-
ton when you have finished listening.
If you wish to keep the squelch open for longer periods without
holding down the button, press the button for at least 5
seconds, until you hear two acoustic sounds (beeps), then release
the button. The squelch will remain open until you briefly press the
button again.
5.6 Selecting transmission power
The transmission phase absorbs the most energy. To extend the bat-
tery duty, you can select low transmission power when transmitting
over short distances. To do this, briefly press the HI/LO button: LOW
will appear on the display (low power is approx. 0.5 W). If you wish to
transmit or receive over long distances or with weak signals, press
the HI/LO button again: LOW will disappear and high power will be
selected (approx. 2W).
The transceiver is factory preset on high power.
5.7 Instant recall of channel 16
Channel 16 is used as the universal marine channel for emergency
communication. Your transceiver is equipped with a button that provi-
des instant access to this channel. To instantly recall channel 16, press
the ch 16 button. Channel 16 will be selected (regardless of the usage
mode selected, except for scanning). To return to the channel selected
previous to channel 16, press the ch 16 button again.
5.8 Display lighting
If environmental light is insufficient for reading the display, you can
activate the backlighting for 10-second intervals by briefly pressing

avoid accidental activation of the functions. To activate the keypad
lock, hold down the HI/LO button until the symbol appears
on the display. This function deactivates all the buttons on the front
of the transceiver. Pressing one or more buttons when in this mode
will cause an audio signal of thee consecutive beeps. To deactivate
the keypad lock and therefore reactivate the function keys, follow the
description above once again.
5.10 Use of CALL button
The CALL button is used to make a call on the channel currently se-
lected and is composed of four two-tone audio sequences (bleeps).
To use this function, briefly press the CALL button. The radio will go
into transmission mode for approx. two seconds, emitting a call. While
this is happening, (call) and (transmission) will appear on the di-
splay, as well as the indicator, showing your relative transmission
power.
Two-tone calling is a special function of Ocean. As such, your party

6 ADVANCED FUNCTIONS (F BUTTON)
The F button enables the user to access the transceiver’s advanced
functions and to change settings as required: selecting the band (INT,
USA, or CANADA), VOX mode, memory programming and recall,
channel scanning, etc. In general terms, to recall/change settings for
various functions:
1) Press the F (Function) key repeatedly to scroll through the available
functions, until you find the one you want.
2) Press the or buttons to set the function currently on the
screen. Depending on the function, you can select On (function
activated), Off (function deactivated), or scroll through the various
values (e.g., from 01 to 06).
3) To store a changed setting, press either the or the F button.
Both will perform the same operation, the difference being that the
returns the radio to Standby, while F selects the next func-
tion.
After following step 1, you must make any changes you wish to
within 10 seconds of each button pressing, otherwise the radio will
return to standby and will storing with the current settings.
6.1 Activating/deactivating keypad tones
Keypad tones are emitted each time a button is pressed in order to
reduce the likelihood of accidentally pressing a button twice. This fun-
ction can be deactivated if you prefer the radio to be silent. To activate
or deactivate the keypad tones, refer to the steps outlined below:
1) Repeatedly press the F key until the icon begins flashing. Below
this icon, the current setting will also flash (On = tones activated or
Off = tones deactivated).
2) Press the or buttons to change the keypad tone to On or
Off.
3) Press the button to confirm the setting change and return to
Stand-by, or press the F key to access the following menu setting.
6.2 VOX mode
VOX (Voice Operated eXchange) enables the user to activate hands-
free transmission (without pressing any buttons) simply by speaking
into the microphone. As such, the user is able to rest the radio on
a nearby surface and speak a short distance from the microphone,
communicating hands-free.
VOX functions best with the optional microphone accessories avai-
lable, which connect to the SPK and MIC CHG jacks. Using these
accessories, the microphone will always be close to the user’s mouth,
and apart from the convenience of being hands-free, this will give the
user an even greater range of movement, especially with the radio
clipped onto the user’s belt.
VOX is equipped with two settings (sensitivity and delay), which
allow for optimal use, as explained below.
If you use an external microphone, once you have finished
using it, do not forget to replace the rubberized protective flap
on the radio.
6.2.a Activation/deactivation of VOX mode
1) Repeatedly press the F key until the VOX icon flashes. Below this
icon, the currently selected setting will appear (On = VOX activated
or Off = VOX deactivated).

18
ENGLISH
2) Press the or buttons to change the VOX mode to On or Off.
3) Press the button to confirm the setting change and return to
Stand-by, or press the F key to access the following menu setting.
6.2.b Setting VOX sensitivity
Adjusting the VOX sensitivity avoids the likelihood of the radio going
into transmission mode because of environmental noise. As such, it
should be adjusted to the minimum level necessary to activate tran-
smission by voice.
1) Repeatedly press the F key until the LE (sensitivity level) icon
flashes. The VOX icon and the sensitivity level currently selected
(from 01 to 06) will flash on the display.
2) Press the or buttons to select the desired level (01 = more
sensitive, 06 = less sensitive).
3) Press the button to confirm the setting change and return to
Stand-by, or press the F key to access the following menu setting.
6.2.c Setting VOX delay
During transmission with VOX, a delay avoids the possibility that, du-
ring short pauses in communication, this function does not return the
radio to reception mode. As such, this function should be set at the
minimum level necessary to guarantee this.
1) Repeatedly press the F key until the dL (delay) appears. The VOX
icon and the delay currently selected (from 01 to 06) will flash on
the display.
2) Press the or buttons to select the desired delay time. Six delay
values are available, in increments of 0.5 seconds (01 = 0.5 secon-
ds, 06 = 3.0 seconds).
3) Press the button to confirm the setting change and return to
Stand-by, or press the F key to access the following menu setting.
6.3 Scanning functions
6.3.a Scanning all channels
Ocean can automatically search for signals throughout the marine
band by scanning, i.e. selecting the channels in rapid sequence. When
a signal is detected, the scanning pauses on that channel and remains
blocked until the signal ends (for a maximum of five seconds), giving
the user a chance to respond to a call, if necessary, before Ocean
automatically begins scanning again. To begin scanning, follow the
steps outlined below:
1) Repeatedly press the F key until the Scan icon and the currently
selected channel begins flashing on the display.
2) Press the or buttons to activate scanning. The transceiver will
begin to explore the marine band channels.
3) The transceiver will continue channel scanning until it picks up a
transmission. When this happens, the transceiver temporarily halts
scanning and remains tuned on that channel for about 5 seconds.
During this time, you have a few options:
• If the communication does not interest you, wait for 5 seconds
or press the or keys to begin channel scanning again.
• If the communication interests you, you can halt scanning by
briefly pressing the or PTT buttons.
4) To exit the scanning mode and return to Stand-by on the currently
selected channel, press the button, or press the F button to
access the following menu setting.
Scanning can also be executed on commonly-used channels only.
For further details, refer to par. 6.5.c.

channels, Dual Watch temporarily pauses, remaining tuned for 5
seconds on the corresponding channel, giving the user a chance
to respond a call. After this pause, the transceiver begins scanning
again.
5) If Dual Watch pauses on a channel on which you would like to send
a transmission, press the PTT button. This will deactivate Dual
Watch, allowing you to communicate normally. To reactivate Dual
Watch, follow the steps outlined above.
6) To exit Dual Watch mode and return to normal reception on the
currently selected channel, press the button, or press the F
button to access the following menu setting.
6.4 International, U.S.A., and Canada bands
Your transceiver is equipped with three types of bands on the VHF
marine band:
• I (International) – used in most of Europe and other parts of the
world
• U (USA) – used in the United States of America
• C (Canada) – used in Canada
These bands ensure correct functioning of your transceiver, depen-
ding on the part of the world you are in. Most channels are identical on
all three bands, but there are key differences.
It is your responsibility to select the proper band (using the
optional PRG-OCEAN programmer); otherwise you may cause
interference with other services or not be able to communicate
at all.
6.5 Memory channels
The transceiver is equipped with 20 memories (from 01 to 20) into

This function is available only on the USA band (ref. par. 6.4), and al-
lows for monitoring at regular intervals if a pre-selected weather chan-
nel emits weather information. When this function is active, during
normal functioning (on any USA marine band channel), the transceiver
will execute periodic controls on the pre-selected weather channel to
detect a particular signal (NOAA tone at 1050 Hz) emitted at the same
time as weather information. When Ocean detects a NOAA signal, it
will interrupt normal operations and move automatically to the weather
channel so you are able to listen to essential weather information.
To activate the automatic weather warning:
