1. DSC functions will not operate until you have entered your user MMSI.
2. The radio channels installed into the radio may vary from country to country, depending
upon the model and government or national communications authority regulations.
3. Lowrance recommends that you check the radio operating licensing requirements of your
country before using the radio. The operator is solely responsible for observing proper
radio installation and usage practices.
4. This radio is designed to generate a digital maritime distress call to facilitate search
and rescue. To be eective as a safety device, this radio must be used only within the
geographic range of a shore-based VHF marine Channel 70 distress and safety watch
system. The geographic range may vary but under normal conditions is approximately 20
nautical miles.
Safety Information

away from your mouth and keep the antenna at least 2 inches (5 cm) away from your head
and body.
The radio must be used with a maximum operating duty cycle not exceeding 50%, in typical
Push-to Talk congurations.
DO NOT transmit for more than 50% of total radio use time (50% duty cycle). Transmitting
more than 50% of the time can cause FCC RF exposure compliance requirements to be
exceeded.
To maintain compliance with the Body Worn conguration use only supplied accessories.
Other body-worn accessories or congurations may not comply with the FCC RF exposure
requirements and should be not be used.
The information listed above provides the user with the information needed to make him or
her aware of RF exposure, and what to do to assure that this radio operates with the FCC RF
exposure limits of this radio.

Section 5 - Sending and Receiving DSC Calls
5-1 What is DSC?
DSC (Digital Selective Calling) is a semi-automated method of establishing VHF, MF, and HF radio calls. It has been designated as an international standard by the IMO (International Maritime
Organization) and is part of the GMDSS (Global Maritime Distress and Safety System).
Currently, you are required to monitor Distress Channel 16, but DSC will eventually replace
listening watches on distress frequencies and will be used to broadcast routine and urgent
maritime safety information.
DSC enables you to send and receive calls from any vessel or coast station that is equipped with
DSC functionality and within geographic range. Calls can be categorised as distress, urgency,
safety, or routine, and DSC selects a working channel automatically.
5-1-1 Maritime mobile service identity
An MMSI is a nine-digit number used on Marine Transceiver capable of using Digital
Selective Calling (DSC). This number is used like a telephone number to selectively call
other vessels.
5-1-2 How can I obtain a MMSI number?
You must obtain a user MMSI (Marine Mobile Service Identity) and enter it into your Link2 in order to use the DSC functions. Contact the appropriate authorities in your country.
If you are unsure who to contact, consult your Lowrance dealer.
The user MMSI is a unique nine digit number, similar to a personal telephone number. It is
used on marine transceivers that are capable of using DSC (Digital Select Calling).
Depending upon your location, you may need a radio station license for the Link-2 . You
may also need an individual operator’s license.
Lowrance recommends that you check the requirements of your national radio
communications authorities before operating DSC functions.
WARNING
This radio is designed to generate a digital maritime distress and safety call to
facilitate search and rescue. To be eective as a safety device, this equipment must
be used only within communication range of a shore – based VHF marine channel
70 distress and safety watch system. The range of signal may vary but under normal
conditions should be approximately 10 nautical miles.
Quickly press the CALL/MENU key to display the DSC CALL menu. You can then select
the DSC call type to send. The channel remains unchanged and allows normal Tx
operation.
