• Do not use the 73VR1100 in an environment where flammable gases are present. This
may result in an explosion.
• Do not disassemble or modify the 73VR1100 in any way. Doing so may result in a fire
or an electrical shock.
• Do not strike the panel of the 73VR1100 with a hard, heavy or pointed object, or press
the panel with excessive force. Doing so may result in panel damage or injury.
• Do not block the 73VR1100’s ventilation openings or use it in areas where heat accu
-
mulates. Additionally, do not store or use it under high-temperature conditions.
• Do not store or use the 73VR1100 in locations subject to direct sunlight, or where exces
-
sive dust or dirt is present.
• The 73VR1100 is a precision instrument. Do not store or use it where large shocks or
excessive vibration can occur.
• Do not store or use the 73VR1100 in environments subject to chemical evaporation
(such as that of organic solvents), or where there are chemicals and/or acids present in
the air.
• Do not use paint thinner or organic solvents to clean the 73VR1100.
• Observe the environmental conditions when using the 73VR1100.
• Wait at least for 5 seconds before turning on the power supply after it has been turned
off. The 73VR1100 may not start up if the time interval is less than 5 seconds.
■
ENVIRONMENT
• Indoor use
• The 73VR1100 is designed to be mounted on a vertical panel. It is not suitable for a
slanted or a horizontal panel surface.
• Environmental temperature must be within 0 to 50°C (32 to 122°F) with relative humidity
within 30 to 85% RH in order to ensure adequate life span and operation.
• Desktop type cannot be mounted on a panel surface.
• The handle and rubber feet cannot be detached from desktop type unit.
■
GROUNDING
• Be sure to determine in advance the most stable grounding point in the environment
and earth the 73VR1100’s FG terminal and that of connected devices (PC) to it in order
to protect the devices from dielectric breakdown.
• Grounding is also effective to eliminate noise that could cause errors in the 73VR1100’s
operation.
■
CF CARD
• Do not turn off the power supply to the 73VR1100 or reset it during recording. The CF
Card may be destroyed.
• Observe the described procedure when you need to replace the CF Card during record
-
ing.
