User manual SONY TCM-21DV

[. . . ] â· The unit will play back normally for a while even after the BATT lamp dims. However, replace the batteries as soon as you can. If you do not, subsequent recording will not be done correctly. At the end of the tape, recording stops and the unit turns off automatically. [. . . ] Insert two size R6 (AA) batteries (TCM-21DV: supplied) with correct polarity and close the lid. â· Do not use a new battery with an old one. â· Do not use different types of batteries. â· When you do not use the unit for a long time, remove the batteries to avoid any damage caused by battery leakage and subsequent corrosion. â· Dry batteries will not be expended when another power source is connected. (Using a Sony HF series cassette tape and playing back with speakers) 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. Recording will be made independent of this control. Connect the AC power adaptor to DC IN 3V and to a wall outlet. The AC power adaptor is supplied only with the TCM-22DV. For other models, use the AC-E30HG AC power adaptor (not supplied). Check your local voltage and the shape of the plug before purchasing. The raised bar near the MIC jack identifies as the jack for a microphone not an earphone. for TCM-21DV/23DV: Use the supplied microphone. For other models: Use a microphone of low impedance (less than 3 kilohms) such as ECM-T115 (not supplied). When using a plug-in-power system microphone, the power to the microphone is supplied from this unit. note When recording with an external microphone, the VOR system may not work properly due to difference in sensitivity. Use a soft cloth slightly moistened in water. Should any problem persist after you have made these checks, consult your nearest Sony dealer. The AC power adaptor is not firmly connected. 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. Tape speed is too fast or too slow in the playback mode. Set it to the same speed as that used for recording. [. . . ] ** If you leave the unit after the tape has been wound or rewound, the batteries will be consumed rapidly. If the tape runs too fast or too slowly, check SPEED CONTROL. For AC operation, use the AC power adaptor recommended for the unit. Connect another equipment to the MIC jack using the RK-G64HG connecting cord (not supplied). [. . . ]
