Mounting in a rack
• Do not cover the top of the unit. Remember, heat is dispersed from the DN-F400’s upper
surface.
• Set up the installation environment carefully. For example, take care to protect the DN-
F400 from heat from other devices. If necessary, use forced ventilation. The surrounding
conditions must meet the specifications described in “SPECIFICATIONS” on Page 21.
• If the DN-F400 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-F400 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.
