Introduction
Thank you for choosing McMurdo for your VHF communication requirements.
McMurdo has supplied the maritime market for many years with communication
products of high quality and excellent design, and considers it of utmost importance
that all products are safe and easy to operate.
The product
The McMurdo F1 DSC VHF radiotelephone is designed to meet the high quality
standard required for a product that plays an important role in the safety of the ship
and its crew. The F1 DSC VHF radiotelephone is easy to operate and gives the
user high quality effective radio communication to other ships as well as to shore
based stations. Installation and maintenance is made very simple and can be
carried out by untrained personnel.
A CD-ROM simulating the operation of the F1 DSC radiotelephone can be obtained
from McMurdo on application. This, when installed on a PC-compatible computer,
simulates the operation of the F1 radio together with a simulation of a second
station for exchange of DSC messages.
VHF DSC Radios
VHF radios communicate on fixed frequency bands called channels. There are 57
public channels, numbered 1 to 28 and 60 to 88. (The system is different in US
waters; setting the radio to US changes to that system.)
Some channels are reserved for particular functions:
Channel 16 is reserved for verbal distress calls and for ‘All Stations’ calls.
This channel must NOT be used for other purposes.
Channel 70 is a channel reserved for digital data (DSC).
DSC (Digital Selective Calling) is a digital function which permits a caller to alert a
particular DSC radio (or group of radios) that a standard radio communication is
requested on a specific channel. In this respect, it is similar to a standard telephone
call in that a specific number can be called; however, once the call is accepted,
communication uses normal radio procedures.
DSC also permits automatic distress call alerting; where the appropriate information
is available from external equipment, the alert includes the vessel’s MMSI number,
its position and the exact time of the distress alert. (The distress call is still made
using conventional radio procedures; the DSC function only alerts other radio users
to the intended call.)
Verbal Communication
Verbal communication is of two types: simplex and duplex.
•
Simplex communication uses a single frequency, so only one transmitter can
be operating at any time. This means that each party in the conversation must
say ‘over’ when stopping transmitting so that the other party knows it is their
turn to transmit. All ship-to-ship communication is in simplex mode. The F1
DSC radiotelephone supports simplex communication.
•
Duplex communication uses two frequencies, so both parties can talk at the
same time. The F1 DSC radiotelephone does not support full duplex operation.
•
There is also a hybrid mode: semi-duplex. In this mode, one of the
communicating parties operates in duplex mode and the other in simplex. A
good example is ship to coast station communications. The F1 DSC
radiotelephone supports semi-duplex communication.
DSC Digital Communication
DSC (Digital Selective Calling) is a system for establishing communication to a
specified address, to a ‘group’ (a pre-defined set of addresses), or to ‘all parties’ for
a digital distress call.
The key feature of the DSC system is the use of the vessel’s MMSI (Maritime
Mobile Station Identity) number to identify each vessel. (This number is treated as
the vessel’s DSC telephone number.) Consequently, before a DSC call can be
made, the originating vessel’s MMSI must be programmed into its radio and the
receiving vessel’s MMSI must be known to the caller.
All DSC communication is on Channel 70. The radio maintains a continuous watch
on this channel for incoming messages, which are immediately reported. This
monitoring also allows the system to transmit only when the channel is free.
The radio responds to three types of DSC message:
All ships calls. These calls are received by all vessels within range of the
transmitter.
Individual calls. These calls are addressed specifically to the radio MMSI
number.
Group calls. When the radio has been set up as a member of a group, it
responds to calls addressed to the group number.

NOTE
Inconvenience may occur if advice disregarded.
In the following text ‘radio’ and ‘transceiver’
all refer to the ‘F1 DSC Radiotelephone’.
Installing and Using the Transceiver Safely
Installation (see also the F1 DSC radiotelephone Installation Manual)
WARNING: Do not connect the transceiver to a mains (line) AC electrical supply, as an
electric shock or fire hazard could result.
CAUTION: Do not connect the transceiver to a DC supply exceeding 16V or reverse the
supply polarity. Damage to the transceiver can result.
CAUTION: Do not bypass the power cable inline fuse (such as cutting the cable shorter).
CAUTION: The transceiver is designed for operation in the temperature range –15°C to
+55°C. Do not install (or use) the transceiver in areas which exceed this range.
CAUTION: The transceiver is water resistant to international standards. However, if either
the transceiver or microphone casing is damaged (e.g. due to heavy impact) then the sealing
cannot be guaranteed.
WARNING: Do not install the transceiver in a position where;
a) the controls of your vessel may be obstructed.
b) it may obstruct your normal movement around your vessel.
c) it may cause bodily injury.
d) it cannot be easily accessed in an emergency.
Use
WARNING: Certain parts of the chassis can become hot during extended periods of
operation, notably the rear panel (connectors and radiator fins). Avoid touching these areas
when the radio is operating.
WARNING: Do not touch the rear connections, notably the antenna connector, when the
transceiver is operating and do not touch the antenna whip (mast) or connecting cable when
operating the transceiver, for RF exposure and electrical safety reasons. Refer to Radio
Frequency Exposure Warning.
WARNING: Opening the transceiver cover will invalidate the warranty. Do not open the
cover when the transceiver is operating, or connected to a power supply.
Maintenance
CAUTION: Avoid using chemical solvents to clean the transceiver as some solvents can
damage the case material.
NOTE: The transceiver contains no user serviceable parts. Return to your Service Agent for
repair.
Radio Frequency Exposure Warning
To meet the current requirements for Radio Frequency Exposure it is necessary to
install the antenna mast correctly and operate the equipment according to the
instructions.
WARNING: The antenna mast must be mounted at a minimum distance
(vertical separation) of 3 metres from the head of any person to meet
international safety directives on Maximum Permissible Exposure (MPE) /
Specific Absorption Rate (SAR).
The assumptions used in this assessment are: full transmit power and a good
antenna are used (assumed to be a 9dBi gain omnidirectional type).
Where no suitable structure exists to achieve a 3 metre vertical separation then the
antenna base must be mounted at least 1 metre above the head of any person
within range and all persons must stay outside the 3 metre safety radius.
WARNING: Do not transmit when persons are closer than 3 metres to the
antenna. If any person (e.g. the operator) must be closer, then a grounded RF
shield should be interposed between that person and the antenna.
Failure to adhere to these limits could expose persons within the 3 metre radius to
RF radiation in excess of the MPE / SAR limits.
Rules of Operation
Licensing
IMPORTANT: In most countries the operator of the transceiver must possess a
current radio telephone licence, and the equipment must be registered (Call
Sign and MMSI number). Please contact the relevant authority in your country
for more information.
IMPORTANT: Normal users of the transceiver should be trained, licensed
operators, but this rule is waived in an emergency and any person can transmit
a Distress Call.
General radio operating procedures
Monitor Channel 16 when not using a different channel. The transceiver is
designed to revert to this channel.
False alarms cost lives and money. Do not make unjustified Distress Calls.
Information you overhear, but not intended for you, must remain private and should
not be used or repeated.
Do not use profane or indecent language.

Power
The Power button is an ON/OFF switch. Because it is separate
from the volume control, there is normally no need to reset the
volume level after switching ON the radio. To switch on the radio
press Power, briefly, until display becomes active.
Volume
The Volume knob is a standard rotary control. It controls the volume of both the
internal and external speakers.
Squelch
The Squelch knob sets the level at which signals become audible. It is used to
suppress the background noise, and should be set at the point where the noise is
just inaudible. Setting Squelch at too high a level may suppress weak signals.

Distress
This control is a button which is concealed by a sprung cover, so
preventing accidental activation of the DSC automatic distress alert
operation.
16
This button immediately switches the radio to a listening watch
on Channel 16. This function takes priority over any activity
other than a distress call.
1/25
This button toggles the output power of the radio between 1W
and 25W on successive operations.
dual watch
This button allows the radio to monitor both the selected channel
and Channel 16 automatically.
To use the Dual Watch function, first set the radio to the desired
channel, then push the dual watch button. The display will alternately display the
selected channel number and channel 16, at a rate which is controlled by the scan
dwell time (refer to the 'Setting Profiles' section for information on this parameter).
Pressing the dual watch button again cancels the dual watch and returns the radio
to a listening watch on the selected channel.
light
This button controls the backlighting of the display and
keyboard.
When the button is first pushed, it sets the keyboard backlight
ON and the display backlight DIM. Successive pushes of the button cycle the

followed by selection of the desired
option (left Action key again).
Once the desired option has been selected, or the
user decides not to effect a change, then the
right Action key (normally labelled Back or Exit)
is pressed to return to previous menu levels, and
ultimately to the standby screen.
This example shows the effect of pressing Menu,
followed by a single press of the Scroll Up key.
Subsequently, pressing the Left Action key
(now labelled Select) will allow the user to
access a menu sub-level called Profiles (radio
settings), and the first sub-menu option is
Scan dwell time.

Basic Telephony Operations
Power On/Off
The F1 radio is switched ON and OFF by the POWER button (see page 1).
When the radio is switched ON, it performs a series of self-tests including memory
and key and display illumination tests. When complete the display shows radio
identity and type information, then switches automatically to a listening watch on
Channel 16.
If any problem is encountered, a message is displayed. These messages and the
appropriate corrective actions are discussed in ‘Appendix C: Error Messages /
Troubleshooting’.
Note that the radio automatically looks for a GPS signal source (connected to the
radio NMEA interface) to provide positional information and time and date. During
the check for a GPS source the display reads Search for position. If GPS is not
available after 2 minutes, the message Pos update not found is displayed for 2
seconds and the missing position, time and date information is represented on the
display by blanks (−−). The screen now appears as follows:
Time / date and position information can
now be entered manually, using the
Update Action-key.
Note: until the user enters time / date and
position information, the radio will emit a
beep every minute as a warning that
important safety data will not automatically
be sent with DSC messages.
Entering Time, Date and Position
Press the Update key. This screen is
now displayed. A cursor (text entry point)
appears (flashing) above the first latitude
character entry point. To move the cursor
to the right press the lower scroll key.
To move left press the upper scroll key.
To enter digits press the numeric keys 0-9.
The cursor moves right one digit for each
digit entered, until the end of the line is
reached. The last character (N or S for
latitude, or E or W for longitude is set by
pressing any key from 0-9, * or #. Each
press changes to E/W or N/S.

pressed) the message Invalid Time will appear for 2 seconds. Note that entering a
time via the Position Update screen will not update the radio clock time 3. It is a
static time, which should be updated every 4 hours as a minimum, where no GPS
data source is available. Clock time (and date) is set in ‘Profiles’ 4
(accessible via the Menu Action key).
The radio internal clock operates only when power is available to the radio, and must be manually set, or the clock sets
itself using a GPS data source.
Please refer to the 'Setting Profiles' section of this manual for details on setting clock time.
Page 7
Receiving and Transmitting
The radio will operate as a basic transceiver for verbal communication without
requiring any information programmed into it.
However, it cannot be used as a DSC communication system before it has a 'profile'
set into it (i.e. as a minimum, the MMSI number must be set).
Please refer to the 'Setting Profiles' section 'Setting the MMSI' for more information.
Listening for Voice Communications (Telephony Calls)
To prepare to listen to telephony calls:
1. Ensure the radio is in the standby state

The Additional Channel can be any available channel.
•
Dual Watch starts by watching the Additional Channel for 850 milliseconds
(ms), then sampling the Priority Channel for 150ms, and returning to the
Additional Channel for 850ms. This sequence continues until activity is
detected on one of the channels.
•
If activity is detected on the Priority Channel the scanning sequence will be
stopped for the duration of the activity and Priority Channel will be displayed in
large characters.
•
If activity is detected on the Additional Channel, then the Additional Channel
will be monitored for 1.8 seconds and the Priority Channel will be monitored for
150ms.

The Dual Watch function can be stopped at anytime by pressing the

Page 20
Channel scanning
Channels may be sequentially monitored for activity using the Channel Scanning
facility of the F1 radio.
While scanning the radio automatically maintains a watch on a channel for the
duration of the set dwell time. The dwell time can be set in the Profiles menu. If no
signal is detected the radio moves to the next channel in the sequence of channels,
which may be the next consecutive channel.
Scan program
Scanning is controlled by Scan Programs (lists of channels to scan) which are
stored in the F1 radio. You can store up to 9 different scan programs
To summarise the features of the Scan Program facility:
•
The transceiver has 10 scan programs (including ‘Scan All’).
•
When ‘Scan All’ is selected all channels available to the operator will be
scanned.
•
Each Scan Program can be configured individually
•
The numbers of channels in an individual scan program is limited to 30 (except
for the Scan All program.
•
All channels available to the operator can be programmed into a scan
sequence
•
The operator can set the Channel Dwell Time within the range
200 milliseconds (ms) to 1.8 seconds, in steps of 50 ms.
•
The Channel Dwell Time can only be varied for the channels in the Scan
Program. (The dwell time for the Priority Channel remains 150 ms.)
To setup the radio for scanning refer to the ‘Scanning All Channels: Creating and
Editing a Scan Program’ section.
Incoming DSC Call During Scanning and Dual Watch
During Scan or Dual Watch incoming DSC calls will be displayed as incoming calls
for 1 minute. When the 1 minute period has elapsed the radio will return to the Dual
Watch or Scan operation, and the LCD screen shows the Scan or Dual Watch
display, as appropriate. A message symbol (/) is displayed if an unread DSC
message has been received.
However if the incoming call is an All Ships Call of the Category ‘Distress, Urgency
or Safety’ the display will continue to show the incoming call and the Scan and Dual
Watch activity will be stopped. In this situation the Scan and Dual Watch activity has
to be reactivated by the operator.
IMPORTANT: The Scan Program only defines the channels to be used from the
legal channels available when the radio is configured by your supplier. It is the
responsibility of the user to ensure that the radio is operating in the correct
channel mode (i.e. International or US) before initiating a scan.

seconds the Priority Channel (normally Channel 16) is monitored for activity. If
activity is detected on any channel the radio will stop scanning and channel on
which activity was selected will remain selected. After 5 seconds of no activity on
the channel, the radio will resume scanning. Squelch level should be adjusted for
correct operation. If the squelch level is too low (control too far counter-clockwise),
scanning will halt. If the squelch level is too high (control too far clockwise), weak
signals may not be heard.
NOTE: During channel scan, channels with a 1W maximum allowable transmission
power requirement cause the radio to select 1W power for those channels.

Transmitting an All Ships Call
When sending an All Ships message, no DSC acknowledgement is required or
possible. Obviously, an All Ships call is not addressed to a specific station and so
does not need the details of the called party; it does, however, give the choice of
Safety or Urgency messages.
An Urgency message is used when safety is threatened but there is no
imminent danger. The verbal information transmitted after an Urgency
message is prefixed ‘PAN PAN’
A Safety message concerns important navigational or meteorological
information. The verbal information transmitted after a Safety message is
prefixed ‘SECURITÉ SECURITÉ SECURITÉ’.
To transmit an All Ships call:
1. Press Menu action key to display top level
menu selection; Send DSC messages.
2. Press Select action key to display the
Send DSC Messages menu.

Received message log
The radio retains two lists of received messages, one for Distress and All Ships
calls, and one for all other calls. Any message which is unread causes an indicator
( / ) to be displayed when the radio is in listening mode.
These lists each retain 20 calls; when a list is full, a new call overwrites the oldest
call in the list.

Distress (and Urgency) messages are treated in exactly the same way, but are
stored (and accessed from) the Distress Log.
As is usual with all such messages, the complete text of the message can be read
by scrolling up and down.
Note: While a call is being displayed, the left Action key shows Select if no
acknowledgement has been sent (and the message is of the type which can be
acknowledged) or Reset if the message has been acknowledged. In the first case,
pressing Select produces a prompt to acknowledge the message. It is thus possible
to defer the acknowledgement of messages until a convenient time; the sender will
then be informed that the called party (i.e. you) is now ready to communicate.

Individual or Group Calls Using the Directory
To Transmit DSC Calls Using a Station or Group Names from the Directory:
Please refer to the ‘Basic DSC Operations: Transmitting an Individual DSC Call
Using Called Station Name’ section, page 15. The Group Stations are accessed,
using the directory, in the same way as Individual Stations.
Page 36
Setting Profiles
The radio cannot be used to transmit in DSC mode until, as a minimum, its MMSI
number has been programmed into it.
Setting the MMSI Number
The MMSI (Maritime Mobile Service Identity) number is a 9-digit identifier which
enables a registered vessel to be identified.
MMSI numbers are of three types: individual, group and coast station.
•
An Individual Number identifies a single radio installation.
•
A Group Number is an assigned number which allows several vessels
to receive a single addressed call (example: a fleet of vessels). Group
Numbers always start ‘0….’
•
A Coast Station number identifies a fixed installation
e.g. a Coastguard radio. Such numbers always start ‘00…’
When the radio is purchased, the supplier may configure the radio with the correct
individual MMSI; otherwise, the MMSI number is normally set to 000000000. This
must be changed before the radio can transmit in DSC mode.
NOTE: Only one individual MMSI number may be stored in the radio.
If the wrong MMSI number is stored, only a Service Agent can remove it.
2 MMSI entry attempts are allowed within 1 hour. Refer to Installation Manual.
1. From the standby screen, press the Menu
key.
2. Scroll through the options to find Profiles.
Press the Select key.
3. Scroll to MMSI number and press Select.
4. The first option displayed in the MMSI
number menu is Ship MMSI number.
Press Select.
5. The MMSI number appears as 000000000;
this must first be cleared.
Press the Clear key repeatedly until the
number is blank. Carefully enter the correct
MMSI number using the numeric keys.
Incorrect entries can be erased using the
Clear key.

Page 37
Group MMSI Numbers
A radio may be a member of up to 4 MMSI groups (for example, a group MMSI
could be assigned to a fishing fleet).
Setting a group MMSI is similar to the process for setting the individual MMSI.
1. After selecting Profiles – MMSI number,
scroll to Group MMSI and press Select.
Group 1 is displayed first;
Groups 2, 3, and 4 are displayed by scrolling.
2. Press Edit to enter the Group MMSI
number. When entering the MMSI number, the
first ‘0’ cannot be changed (because it
identifies a MMSI as a group number). The
Back Action key changes to Clear as you
enter digits.
3. When the Group MMSI is entered, press
Save. The Edit screen, showing the group
MMSI is then displayed and it is possible to
Edit the number again, or use the Back / Exit
key to return to the standby screen.

1. Volume control set too low. (Rotate
volume control clockwise).
2. Squelch level too high. (Back off squelch –
rotate squelch control anticlockwise.)
3. Water in front of speaker. (Drain water.)
1. The squelch level may be set incorrectly
for operation of scanning function. If the
squelch level is too low (control too far
counter-clockwise), scanning will halt. If
the squelch level is too high (control too far
clockwise), weak signals may not be
heard.
1. If, after setting volume and squelch
appropriately, sound still cannot be heard
then the internal speaker may be disabled.
(The transceiver is supplied with the
internal speaker enabled.) To re-enable
the speaker, go to Profiles -> Speaker
settings.
The radio performs a series of self tests when power is first switched on.
The mode-indicator and keyboard LEDs, plus LCD backlight, are cycled, and the
LCD display contrast settings are briefly exercised. During this sequence, internal
self tests (such as synthesiser lock and memory integrity) are performed and the
LCD display shows a progress bar during the test sequence. If errors are detected
the radio will display an error screen. Possible error screens are shown here, each
with an explanation.
Power-Up Self-Tests (1)
Type of Test / Error Message
Error observed
during
initialisation
See Operator Manual
Appendix Page 4
Probable Cause / Solution
This may be caused by a checksum error or
other internal fault. (If the error is still present
after the radio is switched off and on again,
then it will be necessary to consult a Service
Agent, because the radio may be using
incorrect information, and may try to operate
outside its design limits.)
When the radio switches on, it tries to find a
source of GPS derived positional
information, via the NMEA port, and the
display message is ‘Search for Position’. If
no position information is detected within 2
minutes, the display message is ‘Pos update
not found’.
Radio synthesiser lock could not be
confirmed. Operation of the radio is inhibited.
(If the fault persists after the radio is
switched off and on again, then it will be
necessary to consult a Service Agent.)
A fault was found when checking data in the
processor registers.
Operation of the radio is inhibited.
(If the fault persists after the radio is
switched off and on again, then it will be

Probable Cause / Solution
If this test is run within 2 minutes of power-up
and no source of GPS derived positional
information, via the NMEA port, is found the
display message is ‘Pos update not found’.
(Please check the GPS connections.)
If the radio received a valid NMEA
command, but no more GPS information
within 1 minute after that command then the
radio assumes the GPS connection is lost.
Please check your GPS connections.
(Press OK to continue)
Position information is more than 4 hours
old.
(For safety reasons you should re-enter your
position, or if GPS is available, connect your
GPS unit.)
The radio synthesiser lock could not be
confirmed. This can cause problems with
transmission and reception.
Operation of the radio is inhibited.
(If the fault persists after the radio is
switched off and on again, then it will be
necessary to consult a Service Agent.)
