Remote-Controlled Operation When operating the remote control unit, point it towards the remote sensor on the front panel of the unit. (Fig. 4) Battery Installation (Fig. 3) 1. Remove the battery compartment cover. 2. Insert two "AA" (R6, UM-3) dry batteries. Make sure that the batteries are inserted with their positive ± and negative - poles positioned correctly. 3. Close the cover until it clicks. Battery replacement If the operation range from the unit to the amplifier begins to decrease, the batteries are nearly exhausted and both should be replaced. ● Be sure to insert the batteries correctly, as shown in the battery compartment. ● Do not use old and new batteries together. ● Rechargeable and non-rechargeable batteries can be used. Refer to the precautions on their labels. ● When the remote control unit is not to be used for a long time (more than a month), remove the batteries from the remote control unit to prevent them from leaking. Maintenance (Fig. 5) The heads and tape path should be cleaned and demagnetized periodically. Cleaning Tape Path ● Apply head cleaning fluid* to a cotton bud or soft cloth, and lightly rub the heads, capstan and all metal parts in the tape path. ● Also clean the pinch roller using rubber cleaning fluid*. * Both are available in TEAC Tape Recorder Cleaning Kits HC-2 and RC-2 in the U.S.A. or TZ-261 in other areas. Demagnetizing Heads Be sure that the power is off, then demagnetize the heads using a TEAC E-3 demagnetizer. For details of its use, read its instructions. Caution: If the surface of the unit gets dirty, wipe with a soft cloth or use diluted neutral cleaning liquid. Be sure to remove any fluid completely. Do not use thinner, benzine or alcohol as they may damage the surface of the unit. Troubleshooting Basic troubleshooting of a cassette tape deck is similar to troubleshooting any other electrical or electronic equipment. Always check the most obvious possible causes first. To give you a few ideas of what to look for, check the following: ● No power: Is the power cord connected? ● No audio output: Have all connections been made correctly? ● Low sound quality: Are the heads dirty or magnetized? Are you using good quality tape? Has the correct NR System been selected? ● Impossible to enter the record mode: Are the record protection tabs of the cassette in place?
