[. . . ] Do not use a High-position (TYPE II) or metal (TYPE IV) tape, otherwise the sound may be distorted when you play back the tape, or the previous recording may not be erased completely. [. . . ] â· When trying to run on dry batteries, the AC power adaptor has been left plugged in to the DC IN 3V jack, but not to the power source (TCM-343 only). Insert a cassette with the side to start playing facing the cassette holder. There is a raised dot beside VOL to show the direction to turn down volume. At the end of the tape, playback stops and the unit turns off automatically. If you plug in headphones (not supplied) to the EAR jack, you will get monaural output from both left and right channels. Do not leave the unit in a location near heat sources, or in a place subject to direct sunlight, excessive dust or mechanical shock. â· Should any solid object or liquid fall into the unit, remove the batteries or disconnect the AC power adaptor (TCM-343 only), and have the unit checked by qualified personnel before operating it any further. â· Keep personal credit cards using magnetic coding or spring-wound watches etc. [. . . ] **If you leave the unit after the tape has been wound or rewound, the batteries will be consumed rapidly.
