Safety Instruction

WARNING

TO PREVENT FIRE OR SHOCK HAZARDS, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE. ALSO, DO NOT USE THIS UNIT'S POLARIZED PLUG WITH AN EXTENSION CORD RECEPTACLE OR OTHER OUTLETS UNLESS THE PRONGS CAN BE FULLY INSERTED.

REFRAIN FROM OPENING THE CABINET AS THERE ARE HIGH VOLTAGE COMPONENTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

CAUTION

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, MAKE SURE POWER CORD IS UNPLUGGED FROM WALL SOCKET. TO FULLY DISENGAGE THE POWER TO THE UNIT, PLEASE DISCONNECT THE POWER CORD FROM THE AC OUTLET.DO NOT REMOVE COVER (OR BACK). NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

This symbol warns user that uninsulated voltage within the unit may have sufficient magnitude to cause electric shock. Therefore, it is dangerous to make any kind of contact with any part inside this unit.

This symbol alerts the user that important literature concerning the operation and maintenance of this unit has been included. Therefore, it should be read carefully in order to avoid any problems.

Caution:

When operating the LA-1831JMW with a 220-240V AC power source in Europe except UK, use the power cord provided with the monitor.

In UK, a BS approved power cord with moulded plug has a Black (five Amps) fuse installed for use with this equipment. If a power cord is not supplied with this equipment please contact your supplier.

When operating the LA-1831JMW with a 220-240V AC Power source in Australia, use the power cord provided with the monitor.

For all other cases, use a power cord that matches the AC voltage of the power outlet and has been approved by and complies with the safety standard of your particular country.

1810 specifications

The NEC 1810, an innovative microprocessor introduced in the early 1980s, was pivotal in the evolution of computing technology. As the first 16-bit microprocessor in the NEC lineup, it incorporated several advanced features that set it apart from its contemporaries. Designed primarily for embedded systems, the NEC 1810 provided a rich set of functionalities that appealed to a wide range of applications, from consumer electronics to industrial automation.

One of the standout characteristics of the NEC 1810 was its architecture, which boasted a 16-bit data bus and 18-bit address bus. This allowed the processor to access a significant amount of memory, up to 256 KB, enabling developers to create more sophisticated programs than what was possible with 8-bit processors of the time. The ability to handle larger data types also enhanced the execution speed and efficiency, making the NEC 1810 a powerful choice for developers.

The microprocessor was built using CMOS technology, which contributed to its low power consumption and high noise immunity. This was particularly important for battery-operated devices, as it allowed for longer operational periods without the need for frequent recharging. The chip operated at a clock speed of up to 6 MHz, which, while modest by today's standards, was competitive during its heyday.

Another noteworthy feature of the NEC 1810 was its instruction set architecture. The microprocessor supported a variety of addressing modes and offered up to 78 different instructions, including arithmetic and logic operations, data manipulation, and control flow commands. This versatility made it suitable for a wide array of application domains.

The NEC 1810 also integrated several built-in hardware components that simplified the design of peripheral interfaces. This included timers, programmable I/O ports, and even interrupt handling capabilities, allowing developers to create responsive applications without needing extensive external circuitry.

As a member of a growing family of microprocessors, the NEC 1810 played a significant role in the proliferation of personal computers and programmable devices in the 80s. Its combination of efficiency, power, and flexibility made it a favored choice among engineers and designers seeking to push the boundaries of technology. Today, while far surpassed by modern processors, the NEC 1810 remains a noteworthy milestone in the history of microprocessor design, representing an era defined by rapid advancements in computing capabilities.
