JRC NCR-700A NAVTEX RECEIVER (NAVIGATION WARNING RECEIVER)
OVERVIEW OF THE FEATURES OF JRC NCR-300A PRONAV NAVTEX RECEIVER:
Unattended Reception and Print-out of Up-to-date Navigation and Weather Information.
The Navtex receiver automatically receives and prints out Navtex service broadcasts supplied in English. Its function receives and prints out various types of information broadcast at a frequency of 518 kHz, such as navigational warning, meteorological warning, search and rescue information, etc. This equipment also provides a method of programming so that you can select the type of information to be received and from which coast station to receive it.
* Reduced consumption of printer paper
Since the equipment has capability of storing up to 128 message identification codes in memory for up to 72 hrs, duplicate printing of message is avoided.
* Permanent storage of data
Settings once the types of messages to be received and their coast stations have been set, these setting are automatically stored into the internal memory (EEPROM) of the equipment. The data, therefore, does not require resetting, even after power has been turned off.
* High reliability based on digital demodulation
JRC’s unique digital demodulation circuit ensures high reliability.
* Dual voltage supply input
The equipment can be used on either 24-VDC vessels or those with 12-VDC.
* Self-diagnostics
The equipment contains self diagnostic tools, making it easy to service.
* Connection to external equipment
The equipment can be used in conjunction with Integrated Radio Communications System (IRCS) for vessels and the Total Navigator (ECDIS).
