Harman Kardon HK100M Owners Manual - Page 9

Record tabs The plastic case on every blank cas- sette features record tabs. These are found on the TOP LEFT side of the cassette when you hold the cassette with the exposed portion of tape facing down and the appropriate side facing you. To preserve a recording from accidental erasure, break off the appropriate record tab with a small screwdriver. To re-record over a cassette where the tabs have been removed, cover the appropriate tab hole with a piece of adhesive tape. To erase recorded material Recording new material automatically erases previous material. To erase a cassette without recording new material, remove any microphones attached to the MIC jacks (20) and set the INPUT LEVEL control (24) to "0." Then follow instructions for recording using no program source. Maintaining appearance Clean the metal panel with mild, diluted detergent applied with a soft cloth or cotton swab. Never use a strong abrasive cleaner. Remove dust or smudges from the acrylic front window with diluted glass cleaner applied with a soft cloth. Do not use a strong solvent type cleaner or solvent. The hk100M cassette deck is a high- quality precision instrument. If the directions in this manual are followed thoughtfully, the cassette deck should provide many years of musical pleasure. Cleaning capstan and heads The capstan and heads on your cas- sette deck should be cleaned after every 100 hours of use to prevent the accumulation of dirt and other materials that could interfere with recording and playback quality. Press the STOP/EJECT lever (5) to open the CASSETTE DOOR (3). Clean all metal parts that come in contact with the tape with a cotton swab dipped in denatured alcohol. Clean the rubber pinch rollers with an aromatic hydrocarbon, as denatured alcohol will cause them to harden.
