Using DC Power, Listening Safely | Radio Shack SCR-64 specs

1.Press down on the tabs above the battery compartment cover and pull the cover down to remove it.

2.Place the batteries in the compartment as indicated by the polarity symbols (+ and –) marked inside.

3.Replace the cover.

When the sound becomes weak or distorted or the cassette recorder stops operating prop- erly, replace the batteries.

Warning: Dispose of old batteries promptly and properly. Do not burn or bury them.

Caution: If you do not plan to use the cas- sette recorder with batteries for several days, remove the batteries. Batteries can leak chemicals that can destroy electronic parts.

USING DC POWER

You can power the cassette recorder from a 12V power source (such as a vehicle’s cigarette-lighter socket) using a 9V, 500 mA DC adapter and a size M Adaptaplug™ connector (neither supplied). Both are available at your local RadioShack store.

Cautions:

You must use a power source

!that supplies 9V DC and deliv- ers at least 500 mA. Its center

tip must be set to negative and its plug must fit the cassette recorder’s DC 9V jack. Using an adapter that does not meet these specifications could damage the cassette recorder or the adapter.

•Always connect the DC adapter to the cassette recorder before you connect it to the power source. When you finish, dis- connect the adapter from the power source before you disconnect it from the cassette recorder.

1.Set the adapter’s voltage switch to 9V, if necessary, then connect the Adaptaplug to the DC adapter’s cord so the tip reads TIP–.

2.Insert the barrel plug into the recorder’s DC 9V jack.

3.Plug the other end of the adapter into the 12V power source.

Notes:

•If the cassette recorder does not operate properly when you use DC power, be sure the 12V source (such as a cigarette- lighter socket) is clean and that the adapter’s plug is pushed all the way into the socket.

•Disconnect the adapter when you are not using the cassette recorder.

•Internal batteries (if installed) automati- cally disconnect when you plug the adapter into the DC 9V jack.

LISTENING SAFELY

To protect your hearing, follow these guide- lines when you use headphones.

•Set the volume to the lowest setting before you begin listening. After you begin listening, adjust the volume to a comfortable level.

•Do not listen at extremely high volume levels. Extended high-volume listening can lead to permanent hearing loss.

•Once you set the volume, do not increase it. Over time, your ears adapt to the vol- ume level, so a volume level that does not cause discomfort might still damage your hearing.

TRAFFIC SAFETY

Do not wear headphones while operating a motor vehicle or riding a bicycle. This can cre- ate a traffic hazard and could be illegal in some areas.

Even though some headphones let you hear some outside sounds when listening at normal volume levels, they still can present a traffic hazard.

SCR-64 specifications

The Radio Shack SCR-64 was a compact and versatile shortwave radio receiver that gained popularity among enthusiasts during the late 1970s and early 1980s. It was well-regarded for its portability, ease of use, and robust performance, making it an ideal choice for both novice and experienced users interested in exploring the shortwave spectrum.

One of the standout features of the SCR-64 was its broad frequency coverage. It was capable of receiving signals across several frequency bands, typically ranging from 1.6 MHz to 30 MHz, enabling users to tune into a diverse array of stations broadcasting from around the world. This wide range of capabilities made the SCR-64 an excellent tool for listening to international news, amateur radio, and various cultural programs.

The SCR-64 incorporated analog tuning, allowing users to manually select frequencies using a dial. While some modern radios have shifted towards digital displays, the analog dial found on the SCR-64 offered a tactile experience that many old-school radio enthusiasts appreciated. The design facilitated precision tuning, allowing users to fine-tune the reception of distant signals with ease.

Additionally, the SCR-64 boasted a built-in telescopic antenna that significantly improved signal reception. This portable feature ensured that users could easily adjust the antenna's length and angle for optimal listening, particularly in areas with high levels of radio interference. An external antenna jack was also available, enabling enthusiasts to connect more powerful antennas for enhanced reception capabilities.

The radio's user-friendly layout included a simple control panel with clear labeling for volume and tone adjustments. It prioritized an intuitive experience, allowing users to focus on the excitement of discovering new broadcasts rather than getting bogged down by complicated settings.

Powering the SCR-64 was another practical consideration. It operated on regular batteries, making it easily usable in remote locations without access to electrical outlets. Its lightweight design further contributed to its portability, making it a popular choice for travelers and outdoor enthusiasts.

In summary, the Radio Shack SCR-64 was a well-balanced shortwave receiver with impressive features for its time. Its broad frequency range, analog tuning, built-in antenna, and portability made it a cherished option for anyone interested in the world of radio communication. Though technology has advanced significantly since its release, the SCR-64 remains a nostalgic symbol of radio listening culture, continuing to spark interest among collectors and vintage radio aficionados today.
