1 OPERATION RULES
1.1Priorities
•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.
1.2Privacy
•Information overheard but not intended for you cannot lawfully
Be used in any way.
•Indecent or profane language is prohibited.
1.3Radio licenses
1.3.1Ship station license
When your craft is equipped with a VHF FM transceiver, you must have a current radio station license before using the transceiver. 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.
1.3.2Operator’s 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 transceiver or be kept with the operator. Only a licensed radio operator may operate a transceiver. However, nonlicensed individuals may talk over a transceiver 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.

2 INTRODUCTION
The NX2000 is a Class-D Digital Selective Calling (DSC) VHF marine transceiver. Comprised of a VHF marine Radio and a DSC controller, it is very convenient and easy to use. The transceiver is a 1/25-watt, frequency modulated waterproof transmitter/receiver for operations on all currently allocated marine channels as well as 10 expansion channels.
The NX2000 supports the latest GMDSS requirement for non-SOLAS vessels from the International Maritime Organization (IMO). When connected with a GPS, it will display the position and Universal Time Coordinate (UTC) of your vessel.
The NX2000 lets you make digitally selected calls, which are quicker and simpler to make compared with conventional voice calls using channel 16. Should a distress, urgency or safety situation occur, you can depend on the NX2000 to raise an alert quickly, thereby indicating your identity and position automatically through a distress communication on the emergency voice channel.
NEXUS MARINE AB operates a policy of continual development and reserves the right to alter and improve the features/specification of their products without prior notice.

VHF NX2000 |
5.2Full Scan (FS)
This function scans through each channel sequentially until a signal is detected above the squelch level set. Once the signal ends or drops below the squelch level, the Radio will continue scanning. Alternatively, you can instruct the NX2000 to continue scanning even if a signal has been detected on any particular channel by pressing the ▲ key once. When in Full Scan mode, FS will appear on the bottom line of LCD.
Note that the Radio will not transmit, nor will alternative channels be able to be selected while in Full Scan mode. To restore normal operation press (F) key or press channel
(16)key.
5.3Memory Scan (MS)
The Memory Scan operates in the same way as the Full Scan, except that it will only scan channels that have been entered into the Scan Memory. If no channels have been entered into the memory then this function will not be available.
When in Memory Scan mode, “MS” will appear on the bottom line of the LCD.
5.4Tag Channel
This function is to tag or cancel tag on a channel, which means select or unselect a channel for Memory Scan. If a channel is tagged then the “M” indicator will appear on the bottom of LCD.
To tag a channel, enter the desired channel number on the Microphone controller and press “F” on the front panel. Select TAG CH and press “F” again. To delete the tag for a channel, repeat the procedure above.

Press (H/L) key to select high or low output power of RF. A “Hi” or “Lo” indicator will appear on bottom of LCD.
5.10 Time Out Timer
A time out timer is provided to prevent continuous transmissions for periods greater than 5 minutes. In the event that the radio will be needed to transmit for periods longer than 5 minutes, it will be necessary to release the PTT briefly before the 5 minute timer expires.
WARNING
1)Users can press the PTT once again after 5 minutes to continue the transmission. But the radio should be placed somewhere which nobody can touch it to avoid scalding injury.
2)The life of the radio set will be shortened by long time continuous transmission.
