2 FIRST AND FOREMOST… SAFETY!

2.1 Symbols used

For quick and rational reading wehave used symbols tohighlight areas that need your maximum attention, or offer

practical advice or simple information.

! Notes like these,marked with an exclamation mark,highlight avery 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 wesuggest following to obtain

the mostfrom the unit.

2.2 Warning

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

can seriously damage the power stages of transmission.

! Keep the antenna at least2,5 cm from your head and body when transmitting and do not use your

transceiver if the antenna is damaged.

! Do not hold the unitby its antenna! Itis very delicateand important for the correct functioning of the

device.

! PAY ATTENTION TO ATMOSPHERIC CONDITIONS- even though Nautico isdesigned to operatein the most

severe conditions, try not to expose it to excessively humid, dustyenvironmentsand to temperatures

outside the range of -20 to +50°C°. Above all avoid exposure to direct sunlight.

! AVOID EXCESSIVE IMPACTS AND VIBRATIONS, theunit 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 potentiallyexplosive atmospheres. One singlespark

could cause an explosion.

4 PREPARATION

Before using your transceiver, you must be certain that the package includes:

• Transceiver

• 12 VDC Ni-MH rechargeable battery pack

• AC charger cradle complete with power cable

• Antenna

• Belt clip

• User’s manual

If there is something missing or damaged, please contact your supplier immediately.

2 Note.According to the version, the belt clip and rechargeable battery pack may already be installed in the

transceiver

Before going any further,be certain that:

• The 12VDC Ni-MH battery pack supplied is attached to the unit. If itisn’t,please make reference to par. 4.4.

• The antenna is connected, by means ofthe appropriate SMA connection.

• The unit is switched off.

4.1 Recharging the batterypack

The battery pack supplied is a 12V Ni-MHtype and can be charged both when it is attached to the transceiver, and when

it’s separated from the unit; 14 -15 hours are necessary to recharge it completely.

To recharge the battery pack:

1) Insertthe plug on the charger cable into a AC mains supply power socket and the other end into the socket found

on the charger cradle.

2) Place the battery pack or the transceiver firmly into the cradle: charging will then start and will be indicated by a

glowing LED light.

3) When charging has finished, remove the battery pack or transceiver from the cradle and disconnect the charger

cable from the AC mains supply power socket.

! Warning! Do not overcharge the batteries! When the battery pack is completely charged, the charging

process doesn’t stop automatically. Thereforedo not forget to extract the battery pack or transceiver from

the charger as soon as the necessary time has passed,otherwise you could damage the batteries and/or

the transceiver.

! Warning! The use of non genuine chargers or batteries can cause damage to your unit or cause explosions

and personal injuries.

! Warning! Never throw the batteries onto afire, or leave them near heat sources: they can cause explosions

and personal injuries. To dispose of the batteries always follow local norms.

4.2 Memoryeffect of the rechargeable batteries

The Ni-MH(Nickel-Metal-Hydrate) rechargeable batteries arevirtually without what they call “memory effect”. This effect

demonstrates adrastic reduction in the battery duty and can be triggered off if systematically, you recharge the battery

pack before it has totally discharged and/or you do not recharge it completely. To avoid the symptoms of memory effect:

• When possible, only recharge the battery pack when it’s completely discharged (i.e. when the device switches

itself off in normal use)

• Do not disconnect the charger before the necessary time to fully recharge the batteries.

• Provide to fully discharge and recharge your battery pack atleast twice a month.

In each case, the best solution to avoid memory effectis to use two battery packs in rotation: one in use and one spare.

To eliminate memory effect, simply fully discharge the batteries and charge them three or four times.

2 Note:Memory effect should not be confused with the normal battery lifethat is on average 300-400 cycles of

charging and discharging. Itis normal thatthe battery duty is reduced when the batteries are reaching the end of

their life cycle, in this case please change the battery pack.

5 BASIC OPERATIONS

5.1 Switching on/off

To switch the transceiver on, rotate the VOLUMEdial clockwise until you hear aclick: the LCD display will then come

on. To turn the transceiver off, rotate the dial anticlockwise until you hear the click again: the LCD display will then go off.

5.2 Volume regulation

Bring the VOLUMEdial to the halfway level and, as soon as you receive asignal, regulatethe volume to acomfortable

level. Ifyou do not receive a signal,you can use the MONI button described in par. 5.4

5.3 Squelch regulation

Squelch is needed to eliminatethe background noise that you hear in the absence of received signals. Ifyou regulate

squelch correctly, while waiting for acall you will have silentoperation and you will reduce the power drain ofthe battery

pack.

To regulate squelch:

1) Holding down the MONI button, also press the CHL/SQL (UP) or CHL/SQL (DOWN)buttons respectively to

increase or reduce the level.

2) Regulate squelch on the lowest level possible to make the noise you hearin the absence of received signals

disappearing. The display shows squelch settings from 00 to 08.

3) Release the buttons

2 Note:Ifyou regulate the squelch level too high (closed), you will only be able to listen to transmissions with strong

signals, while ifit’s too low(open),you will hearbackground rustling or intermittentdisturbances. Above all, the

correct squelch setting is also important for further functions explained later on.

5.4 MONI (monitor) button

The Monitor button allows you to temporarily exclude squelch so that it is possible to listen to extremely weak signals that

will not open stably. In this way you will avoid hearing such these communications broken up. To activate the monitor

function, press and hold downthe MONI button to listen to all radio traffic on the channel selected. Release the MONI

button when you have finished listening.

5.5 Channel selection

Press the CHL/SQL or CHL/SQL button respectively to scroll up ordownthrough the channels until you find the

desired channel.

2 Note:the marine band does not provide acertain channel numbers. Refer to the frequency table in chap. 9.Above

all, channels can have areception frequency different to the transmission one (duplex channels), or the same

(simplexchannels). Normally, communication between boats can only take place on simplexchannels.

5.6 Transmission and reception

The PTT (Press To Talk) button is found on the upper part of the left side of your Nautico. To transmit:

1) Ensure thatthe channel selected is notdedicated to signal reception only (in this case transmission will be

inhibited) and that nobody else is talking.

2) Hold down the PTT button firmly: TXwill appear on the display.

3) Wait for a fraction of a second and then talk normally at a distance of around 5 cm from the speaker/microphone

of the transceiver.

4) When you have finished, release the PTT button: TXwill disappear from the display.

5) When the unit is receiving (PTT button released) you will automatically receive any communication.

2 Note:during transmission and reception operations, try to keep the antenna in avertical position as much as

possible and make sure that there are no obstacles in the direction ofthe other party.

5.7 Select high and low transmission power

The transmission phase is what absorbs the most energy from the batteries. To extend the battery duty, you can select

lowtransmission power when you only have to transmit in short distances. To do it, hold downthe MONI button and also

Page 10 of 16

press the HI/LO/BAND button:LO appears on the screen. If you want to transmit to long distances or with weak signals,

press the buttons again in sequence to select high power: LO will disappear.With the standard 12 Vbattery pack, high

power is 5 watt, and lowpower 1 watt.

5.8 Lighting the display

If ambient light is not sufficient to let you read the display well, press the LOCK/LIGHT button: it will be lighting for 5

seconds. If you want to switch off the backlight within this time, press the above mentioned button again.

2 Note: lighting of the display absorbs supplementary energy from the batteries. Try to use it in moderation.

5.9 Keypad lock

You can lock the keypad on your transceiver to avoid unwanted commands through accidentally pressing buttons during

transportation.

To activate the keypad lock, hold down the MONI button, then press the LOCK/LIGHT button: the key symbol appears on

the display. This function disables all ofthe keys apart the MONI, PTT, 16 and LIGHT/LOCK keys. To activate the keys

repeat the same process carried outto lock them.

5.10 Programming the CALL channel

The CALL button is used to instantly recall the priority channel ofyour choice.This should be previously programmed as

follows:

1) Press the CALL button.CALL appears on the display.

2) Hold down the MONI button, then press CALL: The display flashes to indicate that you are in the programming

phase.

3) Release all of the buttons.

4) Press the CHL/SQL or CHL/SQL buttons to select the desired CALL channel.

5) Hold down the MONI button, then press CALL to store the CALL channel.
