RF RADIATION INFORMATION
RF RADIATION PROFILE
Your radio is designed and tested to comply with a number of national and international standards and guidelines
GX850 INSTRUCTION MANUAL 3
(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 and is authorised by the FCC for occupational use only. 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 requirements.
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 shall 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 your 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.
RADIO LICENCES
Ship Station License
When your craft is equipped with a VHF FM radio, you must have a current radio station licence before using the radio. It is unlawful to operate a ship station which is not licensed. Inquire through your dealer or the appropriate government agency for a Ship-Radiotelephone license. This license includes the call sign which is your craft’s identification for radio purposes.
Operators License
A restricted Radiotelephone Operator Permit is the license most often held by small vessel radio operators when a radio is not required for safety purposes. The restricted Radiotelephone Operator Permit must be posted near the radio or be kept with the operator.
Only a licensed radio operator may operate a radio. However, non-licensed individuals may talk over a radio if a licensed operator starts, supervises, ends the call and makes the necessary log entries.
A current copy of the applicable government rules and regulations is only required to be on hand for vessels in which a radio telephone is compulsory. However, even if you are not required to have these on hand it is your responsibility to be thoroughly acquainted with all pertinent rules and regulations.
OPERATING RULES
Priorities
• Read all rules and regulations pertaining to priorities and
keep an up-to-date copy handy. Safety and distress calls take priority over all others.
• You must monitor Channel 16 when you are not operating
on another channel.
• False or fraudulent distress calls are prohibited under law.
Privacy
• Information overheard but not intended for you cannot
lawfully be used in any way.
• Indecent or profane language is prohibited.
4 INSTRUCTION MANUAL GX850
The range of VHF transmissions depends on antenna height, transmitter power and the terrain over which the signals pass. For a 5 watt handheld radio like the TX850, ship to ship communications up to 5 nautical miles should be possible. Using an external antenna should allow ship to ship communication of 8 nautical miles or more. Ship to shore ranges will often be greater due to the increased height of the shore antenna.
RANGE
MARINE MOBILE SERVICE IDENTITY
(MMSI)
The MMSI is a 9-digit number used to identify a radio that is capable of using Digital Selective Calling (DSC). The number is used to selectively call other vessels. To setup and use the DSC feature on your radio: Please refer to the ‘DSC’ section of this manual.
USER MMSI
To use the DSC feature you must be registered with the appropriate licensing authority (AMSA in Australia) who will issue you with your unique user MMSI number. Having a registered user MMSI means you can be identified much quicker in an emergency. Once you have obtained your MMSI number you can then enter this into your GX850 to enable DSC operation. Your GX850 is shipped from the factory without a user MMSI number. It is up to the user to obtain a valid MMSI from the appropriate licensing authority.
NOTE: If you don’t register for a User MMSI, you can still
receive DSC distress calls from other vessels however you cannot send a DSC call.
GROUP MMSI
The Group MMSI is used for DSC Group Calls. A Group Call provides a method for contacting a group of vessels with a common interest, for example, alerting all yachts in a race to announce a change in the race conditions. Any number with a leading zero can be used as a Group MMSI, and they do not need to be registered, but the entity deciding on a Group MMSI must use the MID of the host country or country of vessel registration (e.g. 503 in Australia). The Group ID should be based on a key vessel in the Group, and the recommended system is to drop the last digit of the key vessel’s MMSI and place a zero in front.
For example, a fleet of vessels that has a lead vessel with a DSC User MMSI of 503080110 could use the Group MMSI of 050308011. This would then be programmed into all fleet vessels as the special event Group MMSI.
See ‘My MMSI ID Setup’ on page 13 for details on entering a group MMSI.

TIME OUT TIMER
The radio has a built-in time out timer that automatically limits transmissions to a maximum of 5 minutes of continuous operation. This feature is required to prevent accidental blocking of the frequency should your PTT become jammed or be otherwise pressed accidentally.
When the time out timer activates, the transmission will stop, and the radio will return to receive mode. Normal operation will be restored once the PTT is released.
DISPLAYING TIME AND DATE
When the GX850 is not receiving GPS signals, the screen will display the time and date.
To switch the time and date display on or off, press and hold the SQL key for 3 seconds.
DISPLAYING LOCAL TIME
GPS time is received from the satellites in UTC format. To display the time as local time please refer to the GPS Setup option on page 19.
DIGITAL SELECTIVE CALLING
The Digital Selective Calling (DSC) feature on your GX850 uses preformatted digital data messages instead of voice to transmit urgent or important information to another radio. In
GX850 INSTRUCTION MANUAL 11
times of an emergency, DSC can alert all radios within range to a distress message even when a listening watch is not being maintained. This increases the chances of your signal being heard. DSC can also be used to make All Ships Calls, Group Calls and Position Requests as well as routine calls to individual radios.
DSC is part of the Global Maritime Distress and Safety System (GMDSS) which is expected to eventually replace listening watches on distress frequencies and will be used to announce all routine and urgent maritime safety information broadcasts.
DSC AND GPS
DSC operation is enhanced by the in-built GPS receiver in your GX850. By using GPS, your distress call can automatically include your current position and time. If a GPS position cannot be obtained, DSC calls can still be sent and received to alert the operator of another vessel for subsequent voice communication.
DSC calls are automatically sent and received on CH70. The GX850 has two receivers, one of which is dedicated to CH70. Therefore, regardless of which channel you are operating on, the GX850 will not miss a DSC call.
USER MMSI (MARINE MOBILE SERVICE IDENTITY)
A User MMSI is a unique 9-digit number used to identify a DSC capable radio. An MMSI is used to selectively call other vessels. Before you can use DSC, you must enter your User MMSI number into the ‘My MMSI ID’ option in the DSC Menu. If you don’t yet have a User MMSI, please register with your local Maritime Authority (AMSA in Australia - go to http://www.amsa.gov.au/mmsi/ for more details and to download an application form) who will then issue a unique MMSI number. Please refer to the ‘My MMSI ID’ option further below for instructions on entering your User MMSI.
DISTRESS CALLS
To make a Distress Call use the button under the Red DISTRESS cover on the side of the GX850. To make any other DSC call, use the
