CAUTION DURING OPERATION WARNING Do not bring JUE-95LT (EME) close to the fire, or put it in the fire. It causes the explosion, generation of heat, and the ignition of a built-in lithium battery. Do not approach the JUE-95LT (EME) while transmitting, It transmits microwave and strong microwave might be cause injury.

CHAPTER 1. LRIT 1-1 LRIT system overview 1-1-1 What is LRIT system? Long-Range Identification and Tracking (LRIT) is the global monitoring system of ship's movement. (1) LRIT system is obligation facilities of IMO. (2) It is a system that transmits peculiar information of the ship (ship's communication ID and position information) from Inmarsat-C terminals or other communication equipments, by the commands from land.
1.2 LRIT 1-2-1 LRIT mounting requirements By addition of MSC.202(81) SOLAS V 19-1 1-2-1-1 Object ships: International navigation ships Passenger ships(including high-speed passenger ships), cargo ships (including high-speed craft), and mobile offshore drilling units. 1-2-1-2 SOLAS V, 19-1 rule of LRIT(mounting requirements are added) (1)A ship which built after 31 December 2008 (excluding sea area A1 limited navigation ship).
1-2-3 Functional requirements of LRIT terminal By addition of MSC.242(83), MSC.263(84), SOLAS V 19-1 (1) It can be sent LRIT information with 6 hours intervals automatically. (2) It can be control the sending intervals (15 minutes to 6 hours) by remote control from the land. (3) It can be sent LRIT information by polling.

2-2 JUE-95LT Standard components Appearance 2-2-1 EME (NAF-742LT/NAF-253LT) The EME is installed above deck for receiving signals from satellites. The EME is covered with a radome. Fig.2-2-1a EME (NAF-742LT) Fig.2-2-1b EME (NAF-253LT)
2-5 Optional Equipment Dimensional drawing 2-5-1 EXT PSU (NBD-577C) Specification Input voltage: AC 100/220V (typical), ±10% 50/60Hz (typical), Single phase DC 24V (typical), +30%, -20% Output voltage: DC 24V Caution Before installation, do the following procedure. 1. Set the plug “P1” to suitable receptacle according to the input voltage.
CHAPTER 3. OPERATION Before turning on all power switches of JUE-95LT, confirm all the signal cables and power cables are connected correctly. Regarding the details of LED lamp display, switch functions, and connecting cable and connector, refer table 3-1 to 3-3 in next page.

Remarks (1) POWER switch Power ON/OFF the MES. (8) RESET button To reset the status of JUE-95LT when it Refer to chapter 4-6 of this manual and operates abnormally. be careful to handle this button. (It seems to a very little hole.
The following table shows daily maintenance items using general tools. WARNING Do not check or repair the internal equipment of JUE-95LT by yourself. Any electrical work by any person other than our specialized maintenance persons may cause fire or abnormal operation of this equipment or electrical shock for you.
Check all items in the following section to secure normal communication at all times. If any unusual phenomenon occurs in the equipment, send appropriate information to JRC service network to get advice or to request for repair with the results of these items.

RECEIVE approximately 10 seconds). Turn on POWER switch with confirming these lamps are blinking. JUE-95LT may not reboot due to short-circuit of RESET button, if this button is pressed so strongly. NOTE The data, which are received message, call logging history and alarm history, memorized in IME are cleared when RESET button is pushed.
However, in the following case, gratis service cannot be received even if it is during the term of a guarantee. -When the construction report is not sent to JRC after installation of JUE-95LT is completed. -Failure produced by inevitability, such as misuse, negligence, or a natural disaster, a fire, etc.
4-7-4 Disposal When disposing packaging materials of JUE-95LT, follow the rules of the pertinent local government. CAUTION Contact JRC to abandon JUE-95LT (EME). When the lithium battery is short-circuited, receives the impact or it gets wet because of water, it causes generation of heat, the explosion, and the ignition if this is not defended.
