SETTING THE AREA CODE

When you return a call from a Caller ID record (see “Dialing Numbers from a Caller ID Record” on Page 26), your phone automatically dials 1, the area code, and the number. However, if you store your area code into memory and the number you call has the same area code, the ET-1110 only dials the 7-digit local number.

Follow these steps to set the local area code.

1.Pres SETUP. The language selection display appears.

2.Press REVIEW t or s twice. The cur- rently entered area code (or ---) appears.

3.Enter your 3-digit area code, then press SETUP to store it.

Note: If you make a mistake while setting the area code, press DELETE and re-enter the area code.

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.
