INSTALLATION
■Mounting in a rack
•The DN-C640 is of 1U size, allowing it to be mounted in EIA standard 19-inch racks.
When mounting the DN-C640 in a rack, use guide rails or shelf boards, etc., on the rack side to prevent weight from being applied to the front of the DN-C640. The fittings alone cannot support the weight of the DN-C640 (4.3 kg).
Do not cover the top of the unit. Remember, heat is dispersed from the DN-C640’s upper surface.
•Set up the installation environment carefully. For example, take care to protect the DN-C640 from heat from other devices. If necessary, use forced ventilation. The surrounding conditions must meet the specifications described in “SPECIFICATIONS” on Page 44.
•The DN-C640 will work normally when the player unit is mounted with the front panel within 10 degrees of the vertical plane. If the unit is tilted excessively, discs may not load or unload properly.
Max. 10°
DN-C640
•If the DN-C640 is placed near an amplifier, tuner or other components, noise (induced hum) or beat interference may result (especially during AM or FM reception).
If this occurs, separate the DN-C640 from other components or reorient its position.
