Notes
• The rack mounting screws supplied with the MB-23B can be used for the TOA equipment rack only. Do not
use them for other racks.
• Use the Digital Video Recorder in locations with ambient temperature of b5°C and +40°C (41°F and
104°F). When rack-mounting the Digital Video Recorder, the ambient temperature must be kept 35°C (95°F)
or below.
• The Recorder is equipped with an internal cooling fan. Never block the fan exhaust vent.
• Avoid installing the Digital Video Recorder in locations exposed to vibration.
a) Elevated Operating Ambient Temperature - If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration
should be given to installing the equipment in an environment compatible with the manufacturer's maximum
rated ambient temperature (Tmra).
b) Reduced Air Flow - Installation of the equipment in a rack should be such that the amount of air flow
required for safe operation of the equipment is not compromised.
c) Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is
not achieved due to uneven mechanical loading.
d) Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit
and the effect that overloading of circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
e) Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention
should be given to supply connections other than direct connections to the branch circuit (e.g., use of power
strips).
8. RACK MOUNTING
Use the optional MB-23B Rack Mounting Bracket when mounting the Digital Video Recorder in an equipment
rack. Remove 4 rubber feet on the bottom surface by loosening their respective fixing screws with a standard
screwdriver.
