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 International 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 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 rechargeable 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.
