RF Radiation Information

RF Radiation Profile

Your radio is designed and tested to comply with a number of national and international standards and guidelines (listed below)
regarding human exposure to radio frequency electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure
limits for occupational/controlled RF exposure environment at operating duty factors of up to 50% transmitting. In terms of
measuring RF energy for compliance with the FCC exposure guidelines, your radio radiates measurable RF energy only while it is
transmitting (during talking in PTT mode), not when it is receiving (listening) or in standby mode.
The device complies with SAR and/or RF field strength limits of RSS-102 requirement

RF Radiation Safety

In order to ensure user health, experts from relevant industries including science, engineering, medicine and health work with
international organizations to develop standards for safe exposure to RF radiation. These standards consist of:
United States Federal Communications Commission, Code of Federal Regulations; 47CFR part 2 sub-part J;
American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE) C95. 1-1992;
Institute of Electrical and Electronic Engineers (IEEE) C95. 1 – 1999;
International Commission on Non-Ionizing Radiation Protection (ICNIRP) 1998;

FCC Regulations

Federal Communication Commission (FCC) requires that all radio communication products should meet the requirements set forth in
the above standards before they can be marketed in the U.S, and the manufacturer SHAIL post a RF label on the product to inform
users of operational instructions, so as to enhance their occupational health against exposure to RF energy.

Part 15 Compliance

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the 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 off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

● Reorient or relocate the receiving antenna.

● Increase the separation between the equipment and receiver.

● Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.

● Consult the dealer or an experienced radio/TV technician for help. Note: “Changes or modifications to this unit not expressly

approved by the party responsible for compliance could void the user’s authority to operate the equipment.”

EU Regulatory Conformance

As certified by the qualified laboratory, the product is in compliance with the essential requirements and other relevant
provisions of the Directive 1999/5/EC. Please note that the above information is applicable to EU countries only.

TX Time Out

The transmission will be automatically turned off after PTT key pressed over 5 consecutive minutes. The TX mode will

be terminated and back to Rx mode. Once the PTT key is released, the TX time out timer will be reset. PTT key will back to

work normally.

The Local Time & Date on Screen:

UTC TIME LOCAL TIME

When MDA-4 cannot receive the GPS signal to display the current position, screen will automatic display the time and date.
When radio received the GPS signal, screen will show the current GPS location, related UTC time and date will be shown
below the GPS location mark.

Long press “Call/Menu” and enter “GPS Setup” to select the “Time offset” item for setting user’s local time based on
UTC time. Then press “enter” to confirm. User need to pass the entire item from hour-minute-second then able to see enter
option to click and confirm.

In other words, the process is the same as your setup of local time on your computer.

NMEA 0183 and NMEA 2000

The MDA-4 can be connected to both NMEA0183 and NMEA2000 networks. When you connect your radio to a
NMEA 0183 network or a NMEA2000 network, the following data can be transferred; the radio can receive GPS position.
GPS position can be displayed on the screen and is transmitted with DSC calls. When GPS data is not present, the radio will
signal for you to enter your position manually every four hours.

This setting indicates whether you are connected to a NMEA 0183 or NMEA 2000 network; the radio can communicate
over two networks at the same time.

• Intership channels are for communications between ship stations. Intership communications
should be restricted to Channels 6, 8, 72 and 77. If these are not available, the other channels
marked for Intership may be used.

• Channel 70 is used exclusively for Digital Selective Calling (DSC) and is not available for regular
voice communications.

Notes:

1. Channel 06 may also be used for communications between ship stations and aircraft engaged in coordinated search and

rescue operations. Ship stations should avoid harmful interference to such communications on channel 06 as well as to
communications between aircraft stations, ice breakers and assisted ships during ice seasons.

2. Within the European Maritime Area and in Canada, channels 10, 67 and 73 may also be used by

the individual administrations concerned for communication between ship stations, aircraft stations and participating
land stations engaged in coordinated search and rescue and anti-pollution operations in local areas. Channels 10 or 73
(depending on location) are also used for the broadcast of Marine Safety Information by the Maritime and Coast Guard

—25—

Agency in the UK only.

3. Channel 13 is designated for use on a worldwide basis as a navigation safety communication

channel, primarily for intership navigation safety communications.

4. Channels 15 and 17 may also be used for on-board communications provided the effective radiated power does not

exceed 1 Watt.

5. The use of Channels 75 and 76 should be restricted to navigation related communication only

and all precautions should be taken to avoid harmful interference to channel 16. Transmit power is limited to 1 Watt.
