It delivers excellent sound through the supplied in-ear sports headphones or through your speakers, and includes these features: All Weather Design — the sealed cassette compartment protects your tape from wind, dust, and rain. Auto-Stop — automatically stops tape playback at the end of a tape side to protect the tape-handling parts. Bass Boost — provides richer, fuller bass sound. Automatic Frequency Control Circuit — helps lock FM tuning for drift-free reception. Three Power Sources — let you power the SCP-90 from internal batteries, AC power, or vehicle battery power. © 1998 Tandy Corporation. All Rights Reserved.

Note: You need two AA batteries, an AC adapter, or a DC adapter to power the SCP-90.

Your local RadioShack store carries a wide selection of batteries and speakers. 3 14-1233.fm Page 4 Friday, July 2, 1999 10:46 AM CONTENTS Preparation ........................................................... 5 Connecting Power .......................................... 5 Using Batteries ........................................ 5 Using AC Power ...................................... 7 Using Vehicle Battery Power ................... 9 Connecting the Headphones or Speakers .... 12 Listening Safely ..................................... 13 Traffic Safety ......................................... 13 Using the Belt Clip ........................................ 14 Radio Operation ................................................. 15 Cassette Operation ............................................ 17 Playing a Cassette Tape ............................... 17 Tape Tips ...................................................... 21 Tape Quality .......................................... 21 Restoring Tape Tension and Sound Quality ........................................ 21 Maintenance ....................................................... 23 Cleaning the Tape-Handling Parts ................ 24 FCC Information ........................................... 26 Specifications .................................................... 27 4 14-1233.fm Page 5 Friday, July 2, 1999 10:46 AM PREPARATION CONNECTING POWER Using Batteries To power the SCP-90 with batteries, you need two AA batteries (not supplied). We recommend alkaline batteries, such as RadioShack Cat. No. 23-557. Follow these steps to install batteries. 1. Pull up the black cassette compartment latch and pull open the cassette Illust. compartment door. 2. Press the battery compartment cover’s tab in the direction of the Illust. arrow and lift off the cover. 5 14-1233.fm Page 6 Friday, July 2, 1999 10:46 AM 3. Install the batteries over the ribbon, as indicated by the polarity symbols (+ and –) marked inside the compartment. Cautions: • Use only fresh batteries of the required size and recommended type. • Do not mix old and new batteries, different types of batteries (standard, alkaline, or rechargeable), or rechargeable batteries of different capacities. 4. Replace the battery compartment cover, then close the cassette compartment door and latch. If the SCP-90 does not operate properly or if the sound becomes weak or distorted, replace the batteries. Cautions: • Always dispose of old batteries promptly and properly. 6 14-1233.fm Page 7 Friday, July 2, 1999 10:46 AM • Never leave dead, old, or weak batteries in the SCP-90. Batteries can leak chemicals that can corrode or damage electronic circuits. • If you do not plan to power the SCP-90 with batteries for several days, or if you plan to power it using only an AC or DC adapter, remove the batteries to protect the SCP-90 from possible battery leakage. Using AC Power To power the SCP-90 with standard AC power, you need an optional AC adapter, such as RadioShack Cat. No. 273-1654. Cautions: • The recommended AC adapter supplies 3 volts and delivers at least 250 milliamps. Its center tip is set to negative, and its barrel plug correctly fits the SCP-90’s DC 3V jack. Using an adapter that does not meet these specifications could damage the SCP-90 or the adapter. 7 14-1233.fm Page 8 Friday, July 2, 1999 10:46 AM • Always connect the adapter to the SCP-90’s DC 3V jack before you connect it to the AC outlet. Then disconnect the adapter from the AC outlet before disconnecting it from the SCP-90. Follow these steps to power the SCP-90 from a standard AC outlet. 1. Set the adapter’s voltage switch to 3V. 2. Put the adapter’s...
