THE FCC WANTS YOU TO KNOW

In the unlikely event that your phone causes problems on the phone line, the phone company can temporarily discon- tinue your service. If this happens, the phone company attempts to notify you in advance. If advance notice is not practi- cal, the phone company notifies you as soon as possible and advises you of your right to file a complaint with the FCC.

Also, the phone company can make changes to its lines, equipment, opera- tions, or procedures that could affect the operation of this telephone. The tele- phone company notifies you of these changes in advance, so you can take the necessary steps to prevent interruption of your telephone service.

Your phone might cause TV or radio in- terference even when it is operating properly. To determine whether your phone is causing the interference, turn off your phone. If the interference goes away, your phone is causing the interfer- ence. Try to eliminate the interference by:

•Moving your phone away from the receiver

•Connecting your phone to an AC outlet that is on a different electrical circuit from the receiver

•Contacting your local RadioShack store for help

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

Some cordless telephones operate on frequencies that may cause interference to nearby TVs and VCRs. To minimize or prevent such interference, the base of the cordless telephone should not be placed near or on top of a TV or VCR.

LIGHTNING

Your telephone has built-in lightning pro- tection to reduce the risk of damage from surges in telephone line and power line current. This lightning protection meets or exceeds FCC requirements. However, lightning striking the telephone or power lines can damage your telephone.

Lightning damage is not common. Nev- ertheless, if you live an area that has se- vere electrical storms, we suggest that you unplug your phone during storms to reduce the possibility of damage.

ET-1110 specifications

The Radio Shack ET-1110, a remarkable handheld electronic device from the 1980s, is a notable example of early consumer technology that focused on portability and user-friendliness. Originally released as a combination of a pocket-sized calculator and a basic programming tool, the ET-1110 appealed to a wide range of users, from students to professionals.

One of the main features of the ET-1110 is its sleek, compact design. This device was designed to be lightweight and portable, making it easy to carry around in a bag or even in a pocket. The ergonomic layout included a comfortable keypad that allowed users to input data quickly and efficiently. Its liquid crystal display (LCD) made it easy to read under various lighting conditions, a significant advantage at the time.

The ET-1110 was equipped with various functions that catered to both simple arithmetic operations and more advanced mathematical calculations. It featured functions like addition, subtraction, multiplication, and division, alongside square roots and exponentiation, making it a versatile tool for academic and professional use. Additionally, this device supported a limited amount of programming capabilities, allowing users to store and execute simple sequences of commands – an early introduction to what would become a mainstay in personal computing.

In terms of technology, the ET-1110 used CMOS (Complementary Metal-Oxide-Semiconductor) technology, which contributed to its energy efficiency and long battery life. The device typically operated on a small number of batteries, enabling extended use without frequent replacements. This practicality made it an appealing choice for users who needed reliable performance on the go.

Another notable characteristic of the ET-1110 was its affordability, a hallmark of Radio Shack's strategy to make technology accessible to a broader audience. This pricing approach, combined with the device's functionality, made the ET-1110 a popular choice among budget-conscious consumers looking for reliable electronic tools.

The Radio Shack ET-1110 stands out not only as a product of its time but also as a precursor to the sophisticated portable computing devices that would emerge in the following decades. Its blend of practicality, technology, and ergonomic design reflects an era on the brink of massive advancements in personal electronics, marking a significant step in the evolution of handheld devices.
