3-2 System Preparation
3.2 Connecting the Power Cord & Protective
Grounding
This system can work when it is connected to the external power supply or the battery capacity is
sufficient.
NOTE:
When the system is powered by the batteries, imaging modes including static 3D, STE,
STQ, STIC and 4D continuous capturing, self-test, and DVR recording are not supported.
3.2.1 Connecting Power

The connection method is described as follows:
1. Push the retaining clamp upward, and insert the power plug into the receptacle, as shown in
the figure below.
2. Pull the retaining clamp downward to lock the power cord, as shown in the figure above.
3. Plug the power plug at the other end into an appropriate outlet. The grounding terminal should
be connected with a power grounding cable to ensure that protective grounding works
normally.
NOTE:
Be sure to allow sufficient slack in the cable so that the plug will not be pulled out of the
receptacle if the system is moved slightly. If the plug is pulled out accidentally, data may
be lost.
