INSTALLATION IN A RACK

Use the separately sold RM-MRK mounting accessory to install the unit.
Please read before mounting the unit into a rack
This product is warranted to operate in a temperature range of 0–40°C. If this product is mounted in a rack together with other devices, there might be cases in which heat from the various devices causes the temperature inside the rack to rise, so that the product is unable to perform satisfactorily. To prevent the temperature inside the unit from rising, mount the unit in the rack in accordance with the requirements below.

• If this product is mounted together with devices that are prone to produce heat, such as power amps, leave at least 1U of space between it and other devices. Also, be sure to maintain sufficient ventilation in this space by installing a ventilation panel or leaving it open.
• Leave the rear panel of the rack open, and ensure that the rack is at least 10 cm away from the wall or ceiling to allow sufficient air circulation. If you cannot open the rear panel of the rack, install a commercially-available forced ventilation device, such as a fan kit. If you install a fan kit, closing the rear panel may work better for heat dissipation purposes.
  For more information, refer to the owner’s manual for the rack and/or fan kit.
  Caution: If you plan to relocate the rack, be sure to first remove this unit from the rack.
  If this product is moved while mounted in a rack, vibration, etc. might cause the mounting accessory to deform or break, possibly causing injury. There is also a possibility that this unit might malfunction.

[Installation]
The example shown here is for when the long metal fixture is attached to the left side as seen from the front. The procedure can also be used when attaching the long metal fixture to the opposite side.
Notice: If the included rubber feet have already been attached to the unit, remove them.

1. When attaching each metal fixture, place the spacer sheet included between this unit and the metal fixture.
   Using the attachment screws (4 pcs.) included with the mounting accessory, fasten a metal fixture to each side of this unit.
   Warning: Use only the specified screws included with the mounting accessory.
   If the unit falls, injury or damage might occur. This could also cause electric shock or malfunctions.
2. Attach the metal fixtures to the 19-inch rack.
   Attach the metal fixtures to the 19-inch rack using the four included attachment screws of the rack. Be sure to tighten the screws so that they will not get loosened.
   

INSTALLATION ON A DESK

Use the separately sold RM-MTL mounting accessory to install the unit.
Obtain four screws with a diameter of approximately 5 mm (M5 equivalent) that are appropriate for the material and thickness of the desktop.
Carry out the installation through step 4.

Warning: Do not attach this product to anything other than the underside of a desktop.
If the unit falls, injury or damage might occur.
Caution: Installation must be performed by a qualified installer. During installation, pay attention to the following points.

• Choose hardware and a location that is well able to support the weight of this unit
• Avoid locations that are subject to sustained vibration
• You must use the specified installation accessory
• Perform periodic maintenance checks

1. Using four commercially available screws approximately 5 mm in diameter, fasten the metal fixture to the underside of the desktop.
   In the illustration above, the upper part is toward the front.
   Warning: You must use screws that are appropriate for the material of the desktop.
   If the unit falls, injury or damage might occur.
2. Provisionally install the two included screws into the front holes of the mounting accessory attachment holes of this product.
   When doing so, leave a gap of approximately 2 mm between the side of the unit and the head of the screw, so that the screws can engage the metal fixture.
   
3. Slide the unit so that the screws you provisionally installed in step 2 engage the slots of the metal fixture attached under the desk.
   
4. Tighten the four screws in the attachment holes of the mounting accessory.
