CARE

To enjoy your amplifier for a long time:

Keep the amplifier dry. If it gets wet, wipe it dry immediately.

Use and store the amplifier only in nor- mal temperature environments.

Handle the amplifier gently and care- fully. Do not drop it.

Keep the amplifier away from dust and dirt.

Wipe the amplifier with a damp cloth occasionally to keep it looking new.

Modifying or tampering with the amplifier’s internal components can cause a malfunc- tion and might invalidate its warranty and void your FCC authorization to operate it. If your amplifier is not performing as it should, take it to your local RadioShack store for as- sistance.

REPLACING A FUSE

If the amplifier does not operate, you might need to replace the red power cable’s 40- amp SFE-type fuse or one or both of the 20- amp blade-type fuses on the amplifier’s back panel. Check all fuses.

Important: Let the amplifier cool down and see if it starts again before you assume a fuse needs to be replaced.

Caution: Do not use a fuse with ratings other than those specified. Doing so might damage your amplifier.

Replacing the SFE-Type Fuse

1.Disconnect the cable from the vehicle’s negative (–) battery terminal.

2.Push together and twist the fuse holder’s parts on the red power cable until they spring apart. Then remove the fuse.

Fuse

3.If the fuse is blown, replace it. Use only an SFE-type fuse with the proper rating (available at many automotive supply stores). The fuse must be 40 amps.

4.Reassemble the fuse holder by inserting the fuse into the longer of the fuse holder’s ends, and pushing together and twisting the two parts until they latch together.

5.Reconnect the cable to the vehicle’s negative (–) battery terminal.

Replacing the Blade-Type Fuses

1.Disconnect the cable from the vehicle’s negative (–) battery terminal.

2.For each fuse, grasp its plastic end and pull it out of the back of the amplifier.

3.If the fuse is blown, replace it. Use only a blade-type fuse with the proper rating. The fuse must be 20 amps.

4.Grasp the fuse’s plastic end and push it in.

5.Reconnect the cable to the vehicle’s negative (–) battery terminal.

XL-260 specifications

The Radio Shack XL-260 was a pioneering model in the compact scientific calculator market introduced in the early 1980s. This device was particularly well-regarded for its unique blend of functionality, portability, and affordability, making it a popular choice among students and professionals alike.

One of the main features of the XL-260 was its classic LCD display, which offered a clear and easy-to-read output. The display was capable of showing up to 8 digits and allowed for straightforward viewing of calculations. This was particularly beneficial for users who needed to perform complex mathematical computations without experiencing eye strain.

The XL-260 was equipped with a wide range of mathematical functions that catered to different user needs. Basic arithmetic operations such as addition, subtraction, multiplication, and division were always accessible. Additionally, it featured advanced functions including square roots, percentages, and memory storage, allowing users to save and recall values quickly. This made it an excellent tool for engineering students and professionals who often needed to perform numerous calculations.

One of the standout technologies of the XL-260 was its use of solar power, which complemented its battery operation. This hybrid power source ensured that users could rely on the calculator for extended periods without the constant need for battery replacements. The solar panel, situated atop the device, captured light to power the electronic components, showcasing a forward-thinking approach to energy efficiency for consumer electronics during that era.

Another characteristic of the XL-260 was its user-friendly layout. The calculator had well-defined buttons that provided tactile feedback, making it easy to input data accurately. The keys were designed to be durable and responsive, reducing the potential for user error during fast-paced calculations. The compact design and lightweight profile added to its appeal, allowing users to easily carry it in their bags or even pockets.

Overall, the Radio Shack XL-260 represented an important era in the evolution of personal calculators. Its combination of essential features, user-oriented design, and innovative power solutions made it a staple for many during its time. Though the landscape of technology has evolved significantly since its release, the XL-260 remains a nostalgic symbol of early digital calculation devices that laid the groundwork for future advancements in scientific computing.
