Handling the equipment
Completely isolate the equipment electrically
and disconnect all cables from the equipment
before moving it.
When lifting or moving the equipment, always
take its size and weight into consideration. Use
suitable lifting equipment or transporting gear,
or sufficient additional personnel.
Do not insert your fingers or hands in any gaps
or openings on the equipment, for example,
vents.
Do not press or rub on the sensitive surface of
the GUI screens.
If the glass of the GUI screen is broken, liquid
crystals shouldn’t leak through the break due to
the surface tension of the thin layer and the
type of construction of the LCD panel. However,
in the unlikely event that you do make contact
with this substance, wash it out with soap.
Installation
Before installing the equipment:
• Make sure the equipment is correctly
connected to the protective earth conductor
of the mains voltage supply of the system
installation through the mains leads.
• Power to the equipment must be via a fused
spur(s).
• Power plugs must be inserted in socket
outlets provided with protective earth
contacts. The electrical supply at the socket
outlets must provide appropriate
over-current protection.
• Both the mains supply and the quality of
earthing must be adequate for the
equipment.
• Before connecting up the equipment, check
that the mains power supply voltage rating
corresponds with the local mains power
supply. The rating of the mains power supply
voltage is printed on the equipment.
Location
Ideally a cool area is preferred, away from
power distribution equipment or other potential
sources of interference.
Do not install the equipment in places of poor
ventilation.
Do not install this equipment in a location
subjected to excessive heat, dust or mechanical
vibration. Allow for adequate ventilation around
the equipment, making sure that its fans and
vents are not obstructed. Whenever possible,
keep the equipment out of direct sunlight.
Do not place the equipment in an unstable
condition where it might accidentally fall over.
Make sure that the mains voltage and fuse
rating information of the equipment will be
visible after installation.
Audio connections
To ensure the correct and reliable operation of
your equipment, only high quality, balanced,
screened, twisted pair audio cable should be
used.
XLR connector shells should be of metal
construction so that they provide a screen when
connected to the control centre and, where
appropriate, they should have Pin 1 connected
to the cable screen.
Electrostatic discharge
(ESD) precautions
Observe full electrostatic discharge
(ESD) — also known as “anti-static”
— precautions when carrying out
procedures in this manual that are
accompanied by the ESD Susceptibility Symbol
(shown above). This caution symbol shows you
that ESD damage may be caused to items
unless proper ESD precautions are taken, which
include the following practices:
• Keep the work area free from plastic, vinyl or
styrofoam.
• Wear an anti-static wrist strap.
• Discharge personal static before handling
devices.
• Ground the work surface.
• Avoid touching ESD-sensitive devices.
Radio frequency
interference—Class A
device
This equipment has been tested and found to
comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable
protection against harmful interference when
the equipment is operated in a commercial
environment. This equipment generates, uses,
and can radiate radio frequency energy and, if
