REPLACING THE

BATTERY PACK

If you follow the instructions in “Connect- ing and Charging the Battery Pack” on Page 11, the battery pack should last about one year. If the battery pack will not hold a charge for more than 2 hours after an overnight charge, replace it with a new 3.6 V, 600 mAh battery pack that has a connector which fits the socket in the battery compartment. You can order a replacement battery pack through your local RadioShack store.

Install the new battery pack as de- scribed here, then charge the battery pack for 24 hours.

Note: To avoid losing phone numbers stored in memory, try to install and begin charging the new battery pack within about 2 minutes.

1.Press down and slide off the hand- set’s battery compartment cover.

Cautions:

•Use only a replacement battery pack of the required type (3.6 V, 600 mAh rechargeable battery pack).

•Do not dispose of the battery pack in a fire because it can explode.

•Do not open or mutilate the battery pack. Swallowing battery parts can be fatal.

•Be careful not to short the battery pack with conducting materials, such as rings, bracelets, and keys. The battery pack or conductor might overheat and burn.

•At the end of a nickel-cadmium bat- tery’s useful life, it must be recycled or disposed of properly. Contact your local, county, or state hazard- ous waste management authorities for information on recycling or dis- posal programs in your area. Some options that might be available are: municipal curbside collection, drop- off boxes at retailers such as your local RadioShack store, recycling collection centers, and mail-back programs.

ET-928 specifications

The Radio Shack ET-928, released in the late 1980s, is a notable entry in the realm of handheld electronic devices. Primarily designed as a personal organizer, the ET-928 represented the transition from traditional paper planners to electronic solutions that paved the way for modern smartphones and PDAs.

At its core, the ET-928 is powered by a robust 8-bit microprocessor, which provides the device with sufficient computational capabilities for its range of applications. The device features a compact and user-friendly design, allowing users to easily navigate its functions through a straightforward interface. The LCD display, while modest by today’s standards, provides clear visibility of information and is instrumental in the device's ease of use.

One of the main features of the Radio Shack ET-928 is its comprehensive address book function, allowing users to store contact information for personal and professional use. This function is complemented by its calendar capabilities, enabling users to keep track of appointments, meetings, and important dates. The ET-928 also includes a note-taking feature that allows for quick and convenient memos, enhancing its functionality as a versatile planning tool.

In addition to personal organization, the ET-928 incorporates a variety of productivity tools. Among these are basic calculator functions, a world time feature showing different time zones, and a password-protection option to secure sensitive information. These features, while simple by modern standards, were groundbreaking at the time, reflecting the growing need for efficient time management and organization in a fast-paced world.

The technology behind the Radio Shack ET-928 includes its use of non-volatile memory, ensuring that user data is retained even when the device is powered off. This feature was particularly appealing to users, as it provided peace of mind knowing that important information would not be lost.

Overall, the Radio Shack ET-928 is remembered as a pioneering device that combined essential organizational features with early digital technology. Its lightweight design, user-friendly interface, and suite of productivity tools made it a practical choice for individuals looking to streamline their daily tasks. The ET-928 stands as a significant step in the evolution of personal electronics, foreshadowing the multifunctional devices we rely on today.
