23、and the previous stored station will remain instead. NOTE: Storing stations during cassette tape playback is not possible. Operations 5 Important Routine Maintenance To avoid the need for frequent servicing,we strongly recommend periodic clean- ing of the tape head,capstans,and pinch rollers. This w

24、ill also ensure high-qual- ity reproduction of programmed material. The unit should be cleaned after every 20 to 30 hours of operation. A high-quality cassette cleaning cartridge can be used, however, if one is not readily available, proceed as follows: 1. Saturate a cotton swab with isopropyl alcoh

25、ol. 2. While holding the cassette door open, locate the tape head (to the right of the opening and toward the center of the unit). 3. Clean the tape head, capstans and pinch rollers with the cotton swab. 4. Allow parts to dry before operating the unit. Important Antenna Information The CR100A is des

26、igned for connection to various antenna systems as described below. CAUTION:For external use antennas, use No. 8 AWG aluminum wire, or larger, as ground wires for both mast and lead-in, and secure to building structure with insulators spaced 4 to 6 feet apart. Mount antenna discharge unit as closely

27、 as possible to where the lead-in enters the building structure. FM Line Antenna. The CR100A line cord functions as an internal FM Line Antenna for receiving FM broadcasts. For improved reception, particularly in weak signal areas, or for tuners mounted in consoles or racks, installation of the incl

28、uded T wire (dipole) antenna may be necessary. External FM Antenna. If installing a standard 300-ohm antenna system, con- nect the two wires from the T antenna to the screw terminals marked 300- ohm.At the same time, remove any jumper wires connected to these termi- nals. If conditions require the u

29、se of a coaxial transmission line, such as RG-11 or RG-59, connect the coaxial transmission line to the screw terminals marked 75-ohm.Always disconnect any jumper wire connected to the 300- ohm terminals when using external FM antenna. 6 FM Tuner Section Frequency Usable Sensitivity Frequency Respon
