1.3
Receiving a Call on Channel 16
When you hear your call name in the loudspeaker:
1. Lift the handset.
2. Press the PTT key.
3. Repeat the name of the station calling you and say “This is [your ship’s name].”
4. Suggest a channel other than 16 by saying “Channel [suggested number]”.
5. Say “Over” and release the PTT key
to allow your caller to confirm the suggested new channel.
6. Switch to the new channel – for example, channel 71
– and begin your conversation. Only press PTT when you are talking. If you are on a
simplex channel (in other words, a channel that can carry just one transmission at a
time), always say “Over” just before releasing. With duplex channels (ship-shore
calls), the conversation can be two-way as with a normal land telephone call.
Basic
1.4
Making a Radiotelephone Call
A radiotelephone call is preferably to be commenced using DSC. Alternatively the following
public calling procedure shall be used:
1. Select channel 16 (by pressing
) or other agreed channel.
2. Lift the handset.
3. Press the PTT key and make your call.
First, say the name of the station
you are calling three times.
Then say “This is [your ship’s name”], again three times.
Finally, say “Over”.
4. Release the PTT key to listen.
5. When answered, agree upon a channel,
switch to that channel – for example, channel 6 – and begin your conversation. Only
press PTT when you are talking. If on a simplex channel (in other words, a channel
that can carry just one transmission at a time), always say “Over” just before
releasing.
1.5
Speaker Volume
The volume in the loudspeaker (internal and optional external) is adjusted by turning the
VOLUME control. The volume level is visualized in the telephone display. The volume can be
adjusted to a mute state by turning the volume control left (down). If the volume is adjusted
to the mute level the VOL LED will flash.
1.6
Earpiece Volume
The volume level of the default handset earpiece is adjusted selecting the Handset Volume
menu (4.3.1).
The
and
buttons are used to adjust the level. The level is indicated in the
information/message display.
1.7

The squelch level is adjusted using the squelch control. The actual squelch level
is visualized in the telephone display.
0505
1.8
Channel Selection
Basic
The system is defaulting to channel 16 after a normal power-on.
Channels can be selected using the
(increasing to next valid VHF channel) or
(decreasing channel). Channels can also be entered using the numeric keypad.
The active working channel is always shown in the upper display.
1.9
Dual Watch
Dual watch is a mode where the priority channel (16) is scanned periodically for
a signal while listening on a working channel.
Dual watch is activated pressing the DW button.
The DW indicator is lit while DW is active. Dual watch is deactivated by:
•
•
•
•
Pushing DW – Continue to receive on the working channel.
Pushing PTT – Transmit always on working channel
Pushing ´16´.
Pushing Replay - Dual watch is terminated while message is replayed and
will then be re-invoked
Selecting a new channel while in dual watch mode will continue dual watch on the new
selected working channel, unless signal is found on channel 16.
1.10
Replay
Replay is a facility built into the VHF which will allow a copy of the last 90 seconds of
received voice data to be replayed in the loudspeaker.
Recorded voice data will be erased at any power-down.
Activating Replay
The front panel has a dedicated replay button.
A push on replay will bring up a window in the information/message
display. Holding down replay will drive a counter in the display by
which it is determined how many seconds of the latest received voice
data is wanted for replay.
While pressing replay in normal receive mode will still allow the VHF to receive audio in the
speaker system.
When releasing the replay button the replay function will play the last selected seconds of
data received on any channel. During replay new incoming data is not heard, nor recorded.
But incoming voice is recognized in the lower left corner of the display.
Volume control can be used on the replay data to adjust loudspeaker level.
0505
Basic
1.11
Dimming
To adjust the light intensity the Dim button is pressed.
While the Dim button is pressed the intensity is changing. Releasing Dim will
maintain the current light intensity.
A renewed pressing of the Dim button will change the direction of light intensity change.
If the VHF is dimmed to zero, any key press will wake up the light to a minimum visible at
night. Active text in the information/message display might prevent dimming to zero.
It is possible to reduce illumination to zero. If you press a key in this state the light will
illuminate to the lowest illuminated state for 5 seconds, whereafter it will return to the zero
illumination state. If a message is shown on the screen while dimming was set to zero, the
illumination is adjusted to the lowest nonzero value.

Menu Operation
To operate DSC functionality the menu system is used. The main menu can be activated by
. From the main menu all parts of the menu tree can be reached (see
pressing
chapter: Menu Tree).
All menus have a unique hierarchical number. The main menu is the only menu which does
not have a number. The number is (to a certain level) displayed in the upper right corner of
the screen. If more than 6 items are available in the menu arrows shall indicate if remaining
items are to find above (
) current items or below (

A push on
A push on any of the numeric keys (1 to 9) in a menu will quickly select the menu item with
the corresponding number.
A push on
will return to the previous menu window (normally one level up). If the
is pushed in the main menu, the menu is turned off.
Selecting the menus for transmitting DSC calls will lead to a sequence of windows (flows).
The flow sequences are controlled with the
(accept and proceed to next window) or
(cancel and return to the previous window) buttons.
Following a menu hierarchy or a window flow might include a guidance text (e.g. “OK/next”
). Certain windows and lists do not show any guidance texts. These windows can
always be left with
(jumping to main menu) or
(returning to the previous
window).
2.2
Receiving a DSC call
An incoming call will always be recognized by activity on the CALL indicator – and if more
severe (Distress and Urgency calls), also the ALARM indicator. When receiving a DSC call
the message will be displayed immediately in the information/message display, if not
obstructed by any other operations taking place. Received DSC calls will always be accompanied by a sound alarm.
When you receive a call you can read in the display if the call is addressed to All Ships,
ships in a geographic area, a group of ships or to your ship (identified by your MMSI number)
as an individual call.
0505
Basic
If you are busy you can chose to handle the call a little later (e.g. by pushing
which will stop the alarm sound.
Once you are ready to accept the call, lift the handset or press
),
. Your choices
handling the particular call will now appear. Follow the instructions.
If an individual call is received it will not be acknowledged before you accept the call.
2.3

Selecting any of the call types will lead to a call establishing flow with maximum flexibility.
You should make yourself familiar with the flow sequences, but be sure you do not actually
send the message by mistake. In other words, never press
to the transmit
verification window if you do not actually intend to send an emergency call.
Distress calls are always transmitted pushing the DISTRESS button for 5 seconds. After you
have transmitted a distress call the VHF is in distress state (distress call is re-transmitted
once each 3½-4½ minutes). The distress state can only be exited by reception of the
appropriate distress acknowledgement call or if you press
for 5 seconds, or if you
power off the VHF. The VHF will start up in distress state after a power failure.
2.9
DSC Call Log
Received and transmitted DSC messages can be found
with details in the DSC Logs (1.5). A special log contains
distress related calls. The call log system will store the
last (20) calls sorted by date and time.
DSC Logs
1 DSC Distress Log
2 DSC Receive Log
3 DSC Transmit
1.5
Each of the logs and each of the calls within the logs
have their own possible actions upon selection
(e.g. printing).
2.10
Entering Your Position into the System
Ship’s position and the time for that position are essential to the success of a possible
rescue operation. This information is namely automatically added to a DSC Distress call sent
from your VHF. Therefore it is important to always keep this information updated.
Normally a GPS is connected to the VHF. In case of correct installation this will assure the
position and time to be updated correct.
If your VHF is not connected to an external GPS system, or a malfunction of the GPS
connection is detected by the VHF, the VHF will automatically prompt you for updating your
position manually 1 minute after power-up and then every 4 hours. The position and time can
always be entered on your initiative via the Set Position & Time selection in the Settings
menu (4.1.1).

Your VHF in detail
3.1
Abnormal Power-down
If for any reason the main power disappears for a period less than 10 minutes, the VHF will
be able to turn itself on when power is resumed (without pushing ON/OFF).
If the VHF was abnormally powered down, for less than 1 minute the VHF will start up with
the same settings as before the power failure took place (communication channel, volume,
squelch settings, etc.).
3.2
Detail
If the abnormal power down lasted more than 1 minute the VHF might start up with the
settings as they were last time the VHF was turned off normal.
Settings
All volume settings are stored as default during the power off sequence.
3.3
Setting Channel Mode
The VHF carries always international (Int), USA (US) and Inland waterways (BI). Each
country mode needs to be enabled by the authorized dealer to be available for selection. The
selection of the available regions is done via menu (4.4.1). The selected channel mode is
indicated on the front.
Selected country mode is stored as default during power-down sequence.
In Inland waterways (BI) mode it is not possible to use Dual Watch or scanning.
3.4
Private channels
Private channels can be enabled using the service interface only (distributor/dealer).
Enabled private channels become valid for selection on the front. Using the
will simply make the private channel number appear above the highest numeric
channel number. A programmed private channel will be available in any country mode.
Private channels can be selected using the numeric key pad:
•
Private channels:
Long press on
followed by a digit (0-9)
•
Leisure channels:
Long press on
followed by a digit (0-9)
•
Fisher channels:
Long press on
followed by a digit (0-9)
Continued activation of the buttons ´3´, ´5´ or ´7´ will cause the letters F-, L- or P- respectively to be displayed.
0505
11
3.5
Duplex Channels
If duplex channels are selected in the channel table (see chapter: Maritime Channels) the
VHF will operate in semi-duplex mode meaning the VHF is operated simplex but using two
different frequencies for receive and transmit.
Detail
3.6
ATIS (Inland Waterways Only)
ATIS is mandatory to use in inland waterways on e.g. the Rhine. ATIS is a digital data
stream containing ships call sign coded into a DSC-like message, sent over the voice
channel each time the PTT button is released. If PTT is continuously pushed ATIS is
automatically sent each 5 minutes.
ATIS is enabled automatically when BI is selected in menu (4.4.1).
For purpose of operater comfort the received ATIS signal on the active voice channel will be
muted.
The ATIS call sign is programmable from the service interface or from menu 4.4.3. once.
3.7
Transmitter power
Transmitter output power can always be chosen while the radio is active. Pushing the 1W
button will toggle the transmitter power between low power (below 1W) and high power
(below 25W). The 1W indicator is lit when low power is selected. As a default any channel
shift will cause the transmitter power to be adjusted to the maximum allowed on that channel.
3.8
Channel Scanning
Scanning is an extension to the dual watch functionality, by which it is possible to watch
multiple channels. It is possible to scan:
•
•
All channels in a sequence
A number of selected channels in a sequence organized into individual 3 scan tables
- Scan table A, B and C.
The scan type is selectable from the Scanning menu (3). The DW indicator is lit as well
(because the priority channel 16 by default is included in any scan table.
During scan “SC” is shown in the upper display.
If an active signal is found on a channel different from channel 16 the radio remains on that
channel for 10 seconds (but still respecting dual watch requirements), where after scanning
is resumed. The telephone display is displaying the active channel.
If an active signal is found on channel 16 the VHF is locked on channel 16 until the signal
disappears, where after scanning is resumed. The telephone display is displaying the active
channel (16).
While the active scanning window is shown scanning can be terminated by:
•
•
•
•
•
12
Lifting handset off hook
Pushing ´16´ - Channel 16 is used for working channel
Pushing DISTRESS – Initiates DSC distress
Pressing
– Working channel is used as before scanning was entered
(regardless of carrier state).
Pushing Replay - Message is replayed
0505
The active scanning window is active in the graphics display for 30 seconds (or pressing
OK). Then it turns off. After this window has been turned off, scanning can be turned off
using the following:
•
•
•
•
Lifting handset off hook
Pushing ´16´ - Channel 16 is used for working channel
Pushing any numeric key – Normal channel entry
Pushing DISTRESS – Initiates DSC distress
If scanning is terminated (handset hook-off) while an active signal is received, the VHF will
operate on that channel after termination.
3.9
Creating Scan Tables
The scanning tables are user configurable. Creating or editing a scanning table organizing a
subset of channels (e.g. Table A) for scanning is done by selecting the Scanning Table A
menu (3.5.1).
Private channels (non-numeric identifiers – P, F or L) can be part of a channel table. The
number of channels in a scan table is limited to 10.
Scanning tables are stored during the power-down sequence.
0505
13
Detail
If scanning is terminated while no active signal was found, the VHF will receive on the
working channel (as it was before scanning was initiated).

DSC Operations in Detail
4.1
MMSI Number
To operate VHF with DSC the equipment need to be configured with your vessels MMSI
number. If not configured before installation the VHF will inform you at start-up to program
the MMSI number.
Detail
The vessels MMSI number is programmable from the DSC menu (4.5). It can only be
programmed once from this menu after which changing the programmed MMSI will be
possible only through the service interface.
If the MMSI number has been programmed correctly the number is displayed during start-up
4.2
Group MMSI Number
If your radio is configured as member of a group(s) it will receive group calls to that group.
The VHF can be configured to be part of (up to 10) groups. The group MMSI numbers can
be programmed from menu 4.5.2.
The configured group numbers are shown as a list. You can add a group MMSI number by
selecting with
the list entry. Enter a valid group MMSI and press
A group number can be changed by selecting the number
, edit the number and
press OK. A group number can be removed from the list by selecting the number
