1 INTRODUCTION

Congratulations! Your Nautico handheld transceiver is provided with all of the main characteristics of quality, robustness
and reliability that the most advanced technology can offer; it can moreover, be immersed to a depth of 1 meter for 30
minutes. Nautico lets you transmit and receive on all international channels included in the marine VHF band in full
security, as established by the International Telecommunications Union (ITU). This transceiver consists of high quality
electronic components and conforms to the “JIS7” specifications and commercial standards guaranteeing clear, reliable
communication, and many years of perfect functionality. Nautico is controlled by a microprocessor that allows you to
obtain advanced characteristics and services. The microprocessor not only controls the tuning of the marine band, but
also advanced functions such as Dual and Triple Watch, memory channels and much more.

These are the main characteristics of your transceiver:

• PLL (Phase Locked Loop) synthesizer circuit – allows precise and stable channel selection.

• Backlighted LCD display – constantly indicates the parameters and settings programmed on the unit, even in

places with little ambient light.

• Squelch Regulation – in the pauses between transmissions, it eliminates irritating background noise also reducing
power consumption when receiving.

• Channel 16 recall button – allows instant access to channel 16 (the universal marine channel that is used most
frequently, also as the emergency channel).

• CALL button – lets you quickly recall your favorite channel.

• High/low power selector – allows you to save energy by reducing transmission power in short distance

communications.

• Keypad lock – locks the keys to avoid accidental programming.

• Battery weak indicator – it appears when the battery pack is getting discharged.

• Desktop charger as standard – lets you easily recharge the battery pack, separately or installed in your

transceiver.

• Speaker and microphone jacks – through these sockets you can connect suitable external devices (headphones,
microphone/speaker etc.) for easier use, above all in noisy environments.

• Dual and Triple Watch – allow you to monitor channel 16 while listening to another synthesized channel (Dual
watch) and do the same with the CALL channel (Triple Watch)

• Scanning: automatically searches for the signals in the marine band.

• 10 memory channels – you can store the 10 channels that you use most, recalling them in the blink of an eye and

also carry out the scanning process.

2 Note: the manufacturer, in constantly trying to improve the product, reserves the right to change features without

any notice in advance.

2 FIRST AND FOREMOST… SAFETY!

2.1 Symbols used

For quick and rational reading we have used symbols to highlight areas that need your maximum attention, or offer
practical advice or simple information.

! Notes like these, marked with an exclamation mark, highlight a very important description regarding

technical interventions, dangerous conditions, safety warnings, prudent advice and/or very important
information. Ignoring these could cause serious problems and/or damage and/or personal injury.

2 Notes like these, labeled with a memo note, constitute important practical advice that we suggest following to obtain

the most from the unit.

2.2 Warning

! AVOID TRANSMITTING WHEN THE ANTENNA IS NOT CONNECTED – even though the unit is protected, it

can seriously damage the power stages of transmission.

! Keep the antenna at least 2,5 cm from your head and body when transmitting and do not use your

transceiver if the antenna is damaged.

! Do not hold the unit by its antenna! It is very delicate and important for the correct functioning of the

device.

! PAY ATTENTION TO ATMOSPHERIC CONDITIONS- even though Nautico is designed to operate in the most

severe conditions, try not to expose it to excessively humid, dusty environments and to temperatures
outside the range of -20 to +50°C°. Above all avoid exposure to direct sunlight.

! AVOID EXCESSIVE IMPACTS AND VIBRATIONS, the unit is built to support impacts and vibrations,

provided that they are in the norm of any other electronic device.

! Do not use this device and/or change the batteries in potentially explosive atmospheres. One single spark

could cause an explosion.

! BATTERIES – Observe all the precautions on how to use the batteries described in chap. 4.1.
! DO NOT OPEN THE RADIO FOR ANY REASON, the precise mechanism and electrics of which the unit is

composed require experience and equipment; for the same reason the radio should absolutely not be
readjusted, as it has already been calibrated in the factory to provide the maximum service. The opening of
the transceiver by un-authorized personnel will automatically invalidate the guarantee.

! Do not use alcohol, solvents or abrasive materials to clean the unit. Only use soft and slightly damp cloths.

For tougher dirty use a mild detergent.

! Your Nautico handheld marine transceiver incorporates a radio transmitter. Be aware that, when you press

the PTT button, you are radiating radio frequency signals (RF).

2.3 Assistance

We advise you to write the serial number of your transceiver in the space below. You will find this number on the back of
the transceiver. This will be needed in case of assistance and/or loss and/or theft of the unit.

3.1 Description of the parts and commands

Make reference to the following images to localize the various parts of the unit and familiarize yourself with them:

1

1) Antenna – needed to receive and transmit radio signals

2) MONI (monitor) button – temporarily excludes squelch to receive even extremely weak signals

3) PTT (press to talk) button – pressing this button accesses transmission from the equipment

4) MEMO/M.PRG button– recalls and stores the most used marine channels

5) SCAN/DUAL button – if held down, it activates channel scanning/if pressed briefly, it activates Dual or Triple
Watch

6) CALL button – recalls the preferred CALL channel from the memory

7) Speaker/Microphone sockets (protected) – allow connection to external devices (headphones, microphones
etc.)

8) VOLUME control – switches the unit on/off and regulates the audio volume when receiving

9) LCD Display – the LCD (liquid crystal) display constantly indicates the operating state of the device and functions
used

10) CH/SQL/ button– used to move the tuning toward the higher marine channels and increase the squelch level

11) LOCK/LIGHT button– temporarily locks the keys/activates the display’s backlight

12) HI/LO/BAND button – selects low or high transmission power, holding down the MONI button.

13) Button 16 – used to instantly recall channel 16

14) CH/SQL/ button - used to move the tuning toward the lower marine channels and reduce the squelch level

15) Integrated speaker/microphone - the transmission microphone and reception speaker are located here

16) Belt clip – Used to easily attach the unit to your belt during transportation
