FEDERAL COMMUNICATIONS COMMISSION NOTICE
This unit has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15
of the Federal Communications Commission (FCC) Rules. These limits are designed to provide reasonable
protection against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause
harmful interference to radio communications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment o and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected.
• Consult the dealer or an experienced marine electronics technician for help.
This device complies with Part 15 of the FCC Rules. Operation is subject to the condition that this device does
not cause harmful interference.
Unauthorized changes or modications to this equipment may void compliance with the FCC Rules.
RADIO FREQUENCY EXPOSURE SAFETY STATEMENT
Your wireless handheld portable transceiver contains a low-power transmitter. When the push-to-talk button is
pushed, the transceiver sends out radio frequency (RF) signals. In August 1996, the FCC adopted RF exposure
guidelines with safety levels for handheld wireless devices. This device is authorized to operate at a duty factor
not to exceed 50% (this corresponds to 50% transmission time and 50% reception time).
WARNING! To maintain compliance with the FCC’s RF exposure guidelines,
this transmitter and its antenna must maintain a separation distance of at
least 1 inch (2.5 centimeters) from your face. Speak in a normal voice, with
the antenna pointed up and away from your face at the required
separation distance.
Use only the supplied antenna. Unauthorized antennas, modications,
or attachments may damage the transmitter and violate FCC regulations.
Min. 1 inch/2.5 cm

OPERATOR WARNINGS
WARNING! Unauthorized use, changes, or modications to the Nautilus Lifeline may result in violations of FCC
Rules.
WARNING! Disassembly and repair of the Nautilus Lifeline should only be performed by the manufacturer. Any
modication of the serial number or attempt to repair the original equipment or accessories by unauthorized
individuals will void the warranty.
WARNING! The Nautilus Lifeline radio is capable of transmitting on the very high frequency (VHF) marine band.
Use of the VHF marine band is permitted on water only. Use of the VHF marine band on land is prohibited. If
the VHF marine band is used on land and interferes with others communicating, authorities may be notied
and search for the interference. Responsible parties found to be transmitting on the VHF marine band on land
may be ned.
The following communications are prohibited:
• False distress or emergency messages
• General messages (messages not addressed to a particular station), except in an emergency or if you are
testing your radio
• Transmission while on land
• Messages containing obscene, indecent, or profane language (potential ne of $10,000)
LICENSING
You may need a licence to operate your handheld VHF radio. Contact your local authorities before using your
unit to ensure that you are complying with the rules and regulations in your area.
MARITIME MOBILE SERVICE IDENTITY
A Maritime Mobile Service Identify (MMSI) number is a nine-digit number used on marine radios like your
Nautilus Lifeline that are capable of using digital selective calling (DSC). It is used like a telephone number to
selectively call other vessels.
Many countries (but not all) allow use of MMSI numbers. You must apply to your local authorities to obtain an
MMSI number:
Input the MMSI number of your dive boat OR:
• In the United States, register at:
http://www.boatus.com/mmsi or http://seatow.com/boating_safety/mmsi.asp.
• In Canada, visit:
http://www.ic.hc.ca/epic/site/smt-gst.nsf/en/sf01032e.html or http://www.usps.org/php/mmsi/rules.php.
• In Europe, check with the local marine regulatory authority in your country for assistance.
To enter your MMSI number, see Register Your Nautilus Lifeline on page 11. International regulations require
that you contact the manufacturer to change your MMSI. This can be done online.
PARTS SUPPLIED
Before using your Nautilus Lifeline VHF-GPS Radio for Divers, make sure that the following parts are included
in the box:
• One Nautilus Lifeline

HOW THE RADIO AND GPS WORK
Very high frequency (VHF) radio is the most common method of communicating with other boats. Part of
the radio spectrum has been allocated specically to maritime users, and this VHF marine band is the same
worldwide.
Digital selective calling (DSC) is an advanced, computerized form of VHF radio designed for marine use.
When a distress call is made by pressing just one button on the radio, your identication and location may
be automatically transmitted to the Coast Guard and other vessels in the area with a modern VHF radio. This
function is only for emergency use.
A Maritime Mobile Service Identity (MMSI) number is a nine-digit number used on marine radios like your
Nautilus Lifeline that are capable of using digital selective calling (DSC). It is used like a telephone number to
selectively call other vessels. For more information, see the following:
• To obtain an MMSI number: see Maritime Mobile Service Identity Number on page 4
• To enter your MMSI number, see Register Your Nautilus Lifeline on page 11
GPS, short for Global Positioning System, is a means for locating any point on the earth. On your Nautilus
Lifeline, it allows your latitude and longitude position to be acquired as long as you have a clear view of the
sky. This ensures that you can be found even without communicating your position.

Splash-proof and functional in all sea conditions. Do not submerge. If incoming transmissions are mued,
hold unit upside down and gently tap on speaker grill to dislodge trapped or standing water.
Allows you to chat to your dive boat or other divers on a regular transmission channel, or to change the
channel to any marine VHF frequency.
Allows you to talk to every boat within range on channel 16, the universal hail and distress channel on every
marine radio worldwide. Users can change this channel to any marine VHF frequency. Software embedded
in the unit prevents you from accidentally jamming the channel.
Allows you to transmit a distress message and your GPS coordinates by using LocateMe™ Technology.
Your message will usually be shown on the screen of boats with modern marine radios, or a group call will be
made to all radios pre-set to the same MMSI number. Their radios should automatically switch to channel 16,
alarms sound, lights ash, and your GPS coordinates and emergency message should be shown on the screen
of each radio. This function varies according to country and certication.
