0.4 Installation Recommendations
Install the 386 in your rack with the provided rack screws. It is essential that when the 386 is being mounted in a rack mounting enclosure, the unit should be positioned with enough room at least one centimeter at the top and one centimeter at the bottom of the unit to allow prop- er ventilation. The 386 should not be mounted above or below anything that generates exces- sive heat. Ambient temperatures should not exceed 1130F 450C when equipment is in use. Although the unit is shielded against radio frequency and electromagnetic interference, extreme- ly high fields of RF and EMI should be avoided where possible
