4.2 Location for the transceiver
Before continuing, look for a place to install the transceiver which:
Is far enough away from any device sensitive to magnetic/electromagnetic
fields (e.g. compass) in order to avoid interference during their use.
Allows for accessibility to the front panel of KV-300.
Provides easy connection to a power supply, for the antenna and for other
cables.
Has sufficient space close by for installation of the microphone support.
Allows for mounting of the antenna at least 1 meter from the transceiver.
The universal mounting bracket supplied allows for mounting of the transceiver
high up(with the bracket above the device)or on the bridge (with the bracket
below the device) with an angle range of 45 .
* Warning! Installation and connections must be performed in part by
qualified persons.
4.3 Mounting of transceiver
To mount the transceiver to your vessel (see following picture):
1. Choose an appropriate location, as explained in the paragraph above.
2. Position the mounting bracket on the surface upon which it will be fixed,
use a pencil to draw the position of the four holes where the screws will be
inserted.
* Ensure that the surface intended for the transceiver mounting can be dril-
led into without provoking damage to other parts of the vessel and be careful
to not drill right through it.
3. Remove the bracket, drill four holes smaller in diameter than the screws, and
reposition the mounting bracket, aligning it with the four holes.
4. Screw in the mounting screws and ensure the bracket is fixed firmly, using the
screws, the washers, the flat washers and the nuts supplied.
If you are not able to reach the back part of the bracket surface to fix the nuts
onto the screws, use threaded screws to fix the bracket.
5. Tighten the screws with a screwdriver so that the bracket is firmly fixed to the
surface.

6. Align the transceiver on the bracket, ensuring the holes of the internal part of
the bracket line up with those on both sides of the transceiver (you can choose
the preferred notch in order to best adjust the angle of the transceivers front panel
for ease of viewing and use (150 of variation for each notch).
7. Mount the mounting knobs on the two sides of the bracket to soundly fix the
transceiver. Keep the transceiver and microphone at a distance of at least 1
meter from all other magnetic devices (e.g. compass) on your vessel.
4.4 Adjustment of angle
To change the angle of inclination after installation:
1. Loosen the mounting knobs on the sides of the bracket.
2. Adjust the transceiver to a better angle, lining up the holes of the internal part
of the bracket with those on both sides of the transceiver.
3. Tighten the knobs to fix the transceiver into place.
For optimal radio settings and minimal user exposure to electromagnetic
radiofrequency energy, ensure that:
The antenna is connected to the transceiver and is properly installed.
The antenna is situated away from people and is positioned at least one meter
from the transceiver and microphone.
The connector is a standard PL259 (male UHF).
4.6 Mounting of Microphone
To mount the microphone mount, look first
for a mounting point close to the transceiver.
The distance between the transceiver and the
wall mount must be less than the length of
the microphone cable.
Do not pull excessively on the microphone cord.
This part is important to the correct function
of the device: over time, pulling may damage
the cord and impede the user from transmitting.

4.5 Installation of the antenna/electromagnetic exposure

4.7 Connections
Refer to the following diagram:
4.7.1 Power Supply
The transceiver power supply must be 12Vdc. The red cable must be connected to
the positive pin, the black to the negative pin.
Warning! A faulty connection may seriously damage the radio!!
The power cable is equipped with a protection fuse. If the fuse shorts, look for its
reason before substituting the cable with a new one of the same type and value.
Never short circuit it, as this may damage the radio. We suggest using the sup-
plied cable.
4.7.2 GPS device
If your KV-300 transceiver is connected to a GPS receiver such as the
KP32, you can obtain and view NMEA information relative to the current position
the vessel (latitude and longitude) and the local time with respect to Green-
wich Mean Time (GMT).
4.7.3 Antenna
The antenna is an extremely important part of the device and noticeably influences
the settings of any telecommunications device. Contact your supplier regarding
the antenna and request advice about how to mount and best connect it to your
transceiver.
Warning! Ensure the antenna is in perfect working order. It may otherwise
seriously damage the radio! A periodical measurement of the stationary
waves is advised using a suitable SWR metre.

5.1 Turning KV-300 on/off
To turn the transceiver on, rotate the PWR/VOL knob clockwise until it clicks on.
You will hear a beep(acoustic signal)and the LCD display will show the channel
in use.
Important: when you turn on the radio for the very first time, the display will
show channel 16; while usually, KV-300 stores the last channel in use before it's
switched off. To turn the transceiver off, rotate the knob counter-clockwise until
you hear a click.
5.2 Volume adjustment
Bring the OFF/VOLUME knob first to medium volume.Once the transceiver picks
up a signal, adjust the volume t o a comfortable level. If no signal is picked up,
use the squelch control as described in the following paragraph and regulate the
volume using the background noise.
5.3 Squelch Regulation
Squelch is used to eliminate the annoying background noise you hear when no
signal is being picked up. If the squelch is adjusted correctly, there should be
silence in between calls as well as a reduction in battery consumption. To regulate
the squelch:
1. Rotate the SQUELCH knob completely counter-clockwise until you hear the
background noise (if you don't hear anything, increase the volume); RX
will appear on the display.
2. If no signal is being received (only noise), slowly rotate the SQUELCH
knob clockwise,stopping as soon as the noise and RX disappear stably.
If you regulate the squelch level too high (closed), you may hear only
background noise or intermittent discharges.
5.4 Selecting an operating channel
Press repeatedly the UP or DOWN buttons on the keypad or on the microphone
to scroll through the marine channels until finding the desired channel.
Channel 16 is dedicated to the emergencies, therefore we recommend not to use
it for general communications!
Channel 70 is dedicated to DSC communications.
5. BASIC OPERATION
11

5.5 Transmission and reception
Transmitting without a perfectly functioning antenna may seriously damage
the transceiver.
The PTT (Push-To-Talk) button is located on the external microphone of your
KV-300. To transmit:
1. Ensure that no one else is speaking.
2. Hold down the PTT button on the microphone. TX will appear on the Display.
Wait for a second, then speak in a normal voice about 5 cm from the
microphone.
3. When you have finished, release the PTT button: TX will disappear from the
display. Now KV-300 is in receiving mode (silent and waiting for a signal)
and will automatically receive any communication.
5.6 Selecting high and low transmission power
The transmission phase absorbs the most energy. To reduce the risk of wearing
out the battery, we recommend selecting low transmission power when transm-
itting over short distances. Hold the H/L button down (on the radio): Lo (low
power) appears on the display. When transmitting or receiving over long distances
or with weak signals, press the H/L button again. Lo will be replaced with Hi
(high power) on the display.
When the transceiver is tuned to a channel limited to low output power, pressing
the H/L button has no effect.
5.7 Instant recall of channel 16
Channel 16 is a security and distress channel. This channel is used for emergency
communications.
Press the 16 button (the red one on the keypad) and you will be tuned on the
emergency channel.
To return to the channel previously used, simply press the 16 button again.
Do not transmit on channel 16 unless absolutely necessary. Doing so may
impede emergency operations.

6. SCANNING FUNCTIONS
6.1 Channel scanning
KV-300 can automatically search for signals throughout the marine band by
scanning, or selecting the channels in rapid sequence. When a signal is detected,
the scanning pauses on that channel ( RX displayed) and remains blocked until
the signal ends. Before the scanning automatically starts ag ain, KV-300 waits
for a 3,4 seconds in case the user wants to transmit.
You can transmit in any moment, even if the scanning is active. In this case,
the transmission will be done on the channel currently scanned; but if you
transmit just after a signal is detected, the radio will transmit on that channel.
After the transmission, the scanning is interrupted.
If the scanning detects an undesired channel, you can start scanning again by
pushing STEP/SCAN.
To activate the Scan function:
To activate the Mem Scan function:
Reception: if KV-300 detects a signal, the scanning interrupts and the display

8. DIGITAL SELECTIVE CALLING (DSC)
8.1 Introduction
Digital Selective Calling is a semiautomatic method for controlling VHF, MF and
HF radio calls. It was also designed as part of the Global Marine
It is likely that DSC will eventually replace audio calls
on emergency frequencies and will be used to send urgent and routine radio-
transmitted maritime security information. This new service will allow crafts to
send/receive calls of an emergency, urgent, security, or routine nature to/from
vessels equipped with a DSC transceiver.
To avoid accidentally sending a distress call or a call sent incorrectly, contact
your vendor or local authorities for updates on DSC operating and emergency
procedures.
8.2 Mobile Marine Identification Service (MMSI)
Important! To send/receive DSC calls, the user must program his personal MMSI
code into the transceiver. This is a nine-digit number used by marine transceiv-
ers equipped for DSC digital selective calling. This number is used much like a
telephone number for contacting other, specific vessels.
DSC transmissions can be done only if you have been assigned the individ-
ual MMSI code and you entered it in your radio(otherwise the Distress/DSC
controls will be disabled).
Sending a distress call without founded reason is a criminal offence. Never use
this function unless you find yourself in a situation that merits asking for help.

Safety system(GMDSS).
8.3 Navigating the DSC menu
KV-300 offers many DSC function .For this reason it was created.
Once inside a sub-menu, you can return at any time to the main menu by pressing
the PTT button.
To return to the radio mode, confirm EXIT in every menu.
