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, 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 local RadioShack store or an experienced radio/TV technician for help.

If you cannot eliminate the interference, the FCC requires that you stop using your keyboard.

You must use shielded interface cables with this equipment.

Your keyboard can use 6 AA batteries (not supplied) for power. For the best per- formance and longest life, we recommend RadioShack alkaline batteries. ￿

1.Make sure POWER/MODE is set to OFF.

2.Press the tab on the battery compartment cover on the bottom of the keyboard, then pull up the cover to remove it.

3.Place the batteries in the compartment as indicated by the polarity symbols (+ and –) marked inside.

4.Replace the cover.

When the keyboard stops operating properly, replace the batteries. ￿￿￿￿

LK-1161 specifications

The Radio Shack LK-1161 is a notable entry in the realm of personal computing, particularly recognized for its balance of affordability and functionality. Released in the early 1980s, the LK-1161 was a powerful home computer that captured the attention of tech enthusiasts and casual users alike.

One of the standout features of the LK-1161 was its keyboard design, which catered to users looking for an efficient and pleasant typing experience. The integrated keyboard not only streamlined the design of the computer but also provided tactile feedback that many found appealing. This made the LK-1161 a popular option for those who required a reliable interface for programming and word processing.

The LK-1161 was powered by a robust Zilog Z80 microprocessor, a popular choice in many 8-bit computers of that era. This processor enabled the computer to handle various software applications efficiently, making it suitable for both home and educational use. With a clock speed of 4 MHz, users could enjoy a responsive system capable of multitasking between simple applications.

In terms of memory, the LK-1161 was equipped with 64KB of RAM, expandable to higher capacities with additional modules. This flexibility allowed users to adapt the computer to their needs, install more advanced software, or handle larger projects. The built-in BASIC programming language also provided a foundation for users to explore coding, making the LK-1161 a popular choice among budding programmers.

The graphics capabilities of the LK-1161 were modest compared to modern standards but were acceptable for its time. With support for several display modes, users could enjoy text and simple graphics, making the computer suitable for early gaming experiences and educational software.

Storage options included a built-in cassette interface for loading and saving programs, and users could also connect external floppy disk drives to enhance storage capabilities. This adaptability made it easy for users to manage data and software without relying solely on cassette tapes.

Connectivity was another strong point, with RS-232 serial ports allowing users to connect printers and modems. This facilitated data transfer and made it easier to print documents or connect to bulletin board systems.

Overall, the Radio Shack LK-1161 emerged as a versatile computing solution in its era, offering a way for individuals to engage with technology. With its blend of operational efficiency, user-friendly design, and expandability, it remains a memorable piece of computing history, symbolizing the early days of personal computing and its journey towards the modern era.
