In the event that electrolytes gets on skin, wash immediately with water. For eye contact, flush with copious amounts of water for 15 minutes

and see physian.

Section VII - Precautions for Safe Handling and Use

Steps to Be Taken in Case Material is Released or Spilled

Use neoprene, rubber latex-nitrile gloves when handling leakers. If liquid from leaker comes in contact with skin, wash immediately with

water. For eye contact, flush with copious amounts of water for 15 minutes and see physian.

Waste Disposal Method

Do not incinerate since battery may explode.

Precaution to Be Taken in Handling and Storing

The battery is extremely sensitive to adverse effect of humidity. Be sure to store them in a place which is dry and subject to little temperature

change. Do not place near the boiler or radiator, nor expose to the direct sunlight. Do not dispose of the battery in fire. Do not charge the battery.

Do not short-circuit the battery. Do not put in backward position. Do not disassemble the battery, handling in such manner can cause the battery

to explode, leak and injury.

Other Precautions

Install batteries in accordance with equipment instructions. Replace all batteries in equipment at the same time. Do not mix battery systems of

different types. Do not carry batteries loose in your pocket or carrying bag. Check batteries periodically when in use.

23-154, 23-449, 23-149A specifications

Radio Shack, once a titan in the world of electronics, offered a wide range of products through its stores, including a series of iconic multimeter models, notably the 23-149A, 23-449, and 23-154. Each of these multimeters was designed to cater to both hobbyist and professional needs, combining functionality, reliability, and ease of use.

The Radio Shack 23-149A multimeter was known for its compact design and versatility. It featured a digital display that provided clear readings of voltage, current, and resistance, making it suitable for a variety of applications, from simple household projects to more complex electronic tasks. The device supported both AC and DC measurements, a critical feature for users needing accurate readings from different sources. Its durable build allowed for extended usage, appealing to both DIY enthusiasts and professionals in the field.

Moving on to the Radio Shack 23-449, this model introduced enhanced capabilities and more advanced features. It included a peak hold function that enabled technicians to capture transient signals, which is particularly beneficial for diagnosing electrical problems in circuits. The 23-449 also boasted a larger display, making it easier to read measurements at a glance. Moreover, it offered a range of measurement functions, including capacitance testing, which expanded its applicability beyond traditional multimeter functions. The model's robust design and reliability made it a favorite among those working in technical and engineering roles.

Lastly, the Radio Shack 23-154 distinguished itself with its comprehensive range of features. It included data hold, allowing users to freeze a measurement on the display for further analysis. The 23-154 also provided a built-in speaker for audible continuity tests, which facilitated quick checks in wiring and connections. Another notable characteristic was its auto-ranging capability, which simplified the measurement process by automatically selecting the appropriate range for voltage, current, or resistance, enhancing user efficiency.

All three models—23-149A, 23-449, and 23-154—shared common ground in their usability and reliability, embodying the spirit of Radio Shack’s commitment to quality electronics. They are a testament to the brand's legacy in the tech community, remembered fondly by both hobbyists and professionals alike for their practicality and performance. As users reminisce about these models, they reflect on a time when Radio Shack was synonymous with innovation in electronics.
