II. Installation Guidelines
II-1 Installation Environment Requirements
In order to ensure the reliable operation of your Mobile Digital Recorder (MDR) within the terms of the product
warranty, follow these instructions for installing your MDR
a) Follow all electrical codes, adhere to all requirements for your vehicle and for other connected
equipment while installing and operating the MDR.
b) Use only a regulated 12-volt DC or 24-volt DC (2 ~ 3 Amps) certified power supply for installation in
vehicles. The MDR can handle power ranges from 7v ~ 28v DC. Follow the installation and
operating instructions provided to ensure a steady and reliable source of installation. Handle all
electric equipment and connections properly to avoid injuries.
c) Even though the recording unit may not be turned on, live power exists in the mounting assembly
and precautions should be taken to avoid shock. Disconnect the power supply from its source
before connecting or disconnecting the MDR mounting assembly from the power supply.
d) Do not attach any device specified or approved by Vendor.
e) Do not attach powered input leads that exceed 12-volt DC at 1.5 Amps OR 5-volt DC at 1.5 Amps
supply on any one connection.
f)
Attach the MDR ground cable to the vehicle correctly to complete the power circuit.
g) Install the MDR in a dry location shielded from direct contact with excessive humidity and moisture,
rain or other sources of liquid spills. Do not install on a recessed surface where liquids may
accumulate or under surfaces where liquids may drip.
h) Do not handle the MDR with wet hands, while standing in water, or while in contact with other
sources of water or moisture that could create a shock hazard.
i)
Install the MDR out of direct sunlight and away from direct sources of heat.
j)
Do not mount the unit to a surface subject to excessive vibration.
II-2 Mounting / Enclosing the MDR
a) MDR may be operated in a totally sealed enclosure with no cooling airflow, ensure that the operating
temperature of the MDR does not exceed 140°F (60°C) or that the standing temperature does not
exceed 175°F (80°C). The minimum operating temperature for the MDR is -20°F (-28°C). If the
minimum temperature is expected to exceed connect an auxiliary heat source.
b) MDR assembly may be mounted on a flat surface, provide at least 6 inches (15cm) clearance for
cooling airflow around the remaining sides to provide adequate heat dissipation.
c) To clean any surface of the MDR, use only cleaners approved for electronic equipment or
components. Avoid chemical or household cleaners.
d) Disconnect MDR mounting assembly from the power supply when not in use for extended period of
time.
