Chapter 3 Preparing the System for Use
3.1 Site Requirement
3.1.1 Operation Environmental Requirement
The following environmental conditions are within system tolerances for operation:
Strong radiation sources or powerful electromagnetic waves (e.g. electro-magnetic waves from radio
broadcasting) may result in image ghosting or noise. The system should be isolated from such radiation
sources or electromagnetic waves.
Environment
Operation Transportation & Storage
Temperature
10℃～38℃ -10℃～50℃
Relative Humidity
30%～75% ≤80%，non-condensing
Atmosphere Pressure
700hPa～1060hPa 700hPa～1060hPa
NOTE: While the temperature of environment is between 0
℃
to 38
℃
, the system can work
continuously in normal. If the temperature of environment is over 38
℃
, the system can detect the
temperature and stop working while overheating.
3.1.2 Electrical Requirements
Power Requirements：DC 5V
Power Consumption：≤10VA
Voltage Fluctuation
±5%
WARNING: Maintain a fluctuation range of less than ±10% of voltage labeling on
rear panel of the system, otherwise the system may be damaged.
