1 INTRODUCTION
Congratulations on choosing Ocean! Your handheld marine transc eiver was designed as a high-quality, robust, and
reliable marine radio, using the latest technology availabl e. Ocean ensures secure transmission and reception on all
VHF marine channels, as required by the International Telecommunications Union (IT U). Your transceiver is composed
of the highest-quality electronic components, conforms to EN 301 178-2, CE/99/05 re gulations, 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 channels.
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 parameters 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, prolonging 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 channel signals.
• Dual Watch – for monitoring of radio traffic on two channels simultaneously.
• VOX (Voice Operated eXchange) – activates transmission when the user begins speaking. When used with optional microphone
accessories, this feature enables the user to operate hands-free, clipping 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
reducing the risk of interference.
• Multifunctional bar indicator– in reception mode, this function indicates the incoming signal strength using a series of bars. In
transmission 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 recharge able or alkaline, for maximum
flexibility 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 symbol s to highlight urgent situation s, practical advice, and gener al
information.
! Symbols such as this one indicate a crucial description regarding technical repairs, dangerous conditions, safety
warnings, advice, and/or other important information. Ignoring these s ymbols may result in serious problems and/or
damage and/or personal 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 reference.
! 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 marine 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 connecte d – although the radio is protected, this may seriously damage its R.F.
power stages. Do not use your transceiver if the antenna is damaged.
! Keep the antenna at least 2.5cm from your head a nd bod y during trans mission, and keep a dista nce from other el ectrical
devices. Your transceiver contains a radio transmitter. Be aware that, w hen 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 de vice is adequatel y protected from RF e nergy. Your p hysician
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 – alt hough Ocean was designe d to operate u nder the most se vere conditions,
it is important to avoid exposure to environments that are excessively 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 o perating condition, in order to ensure
maximum protection against humidity and atmospheric agents.
! Although this radio was designed to be water resistant, avoid getting it w et as much as possible and do not let any
liquids fall on it. If the transceiver or one o f the accessories gets wet, dry it off as soon as possible with a soft, clean
cloth. If you feel that liquid may have penetrated the radio’s housing, contact a service centre for a diagnostic check.
! Do not use the radio, its accessories, and/or sub stitute the batteries in potentially explosive environments. A single
spark may cause an explosion.
! Do not open the radio for any reason! Ocean’s precision mechanics and electronic s require experience and specialized
equipment; for the same reason, the radio should u nder no circums tances be realigne d as it has alread y been calibrated
for maximum performance. Unauthorized opening of the transceiver will void the warranty.
! Use original accessories only; otherwise you may seriously damage your handheld transceiver.
! Turn off the radio before cleaning it. For further information, refer 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.
Page 5 of 24
! Never throw batteries into a fire or expose them to high temperatures; doi ng 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 unapproved 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 batter y 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 socket that has been grounded.
! Avoid shocks and excessive vibrations. Do not use the batter y 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 b e performed exclusively by authorized s ervice centers. For
further information, contact your local supplier.
! To reduce the risk of electrical shocks, disconnect t he power cable before performing cleaning or maintenance. Gras p
the plug (not the cord!) when removing it from the socket. Use of inappropriate extension cords may cause fire or
electrical shocks.
! Do not expose the batteries directly to temperatures outs ide the -20°C to +35°C range during storag e and do not charge
them in temperatures outside the +5 to +55°C range.
