INSTALLATION
■ Mounting in a rack
• The DN-F300 is of 1U size, allowing it to be mounted in EIA standard 19-inch racks.
• Do not cover the top of the unit. Remember, heat is dispersed from the DN-F300’s upper
surface.
• Set up the installation environment carefully. For example, take care to protect the DN-
F300 from heat from other devices. If necessary, use forced ventilation. The surrounding
conditions must meet the specifications described in “SPECIFICATIONS” on Page 15.
• If the DN-F300 is placed near an amplifier, tuner or other components, noise (induced hum)
or beat interference may result (especially during AM or FM reception).
If interference occurs, disconnect the DN-F300 or change the installation place.
• If the unit is not to be mounted in a rack, remove the rack mount brackets and attach the
included feet.
