Important Safeguards and Warnings
This chapter describes the contents covering proper handling of the Radar, hazard prevention,
and prevention of property damage. Read these contents carefully before using the Radar,
comply with them when using, and keep the manual well for future reference.
Operation Requirements
 Make sure that the barrier will not jitter obviously, and when installing guardrail at one side
of the lane, secure the guardrail to prevent it from moving back-and-forth or jittering.
 After installing the Radar, please insulate the exposed cable cores.

Install the Radar 60 cm (23.6'') away from the ground (70 cm (27.6'') is recommended
when large trucks are frequently seen).
 Do not impact the Radar. Prevent the Radar from falling down.

Do not place metal objects in the range of 0.5 m (1.6 ft) right in front of the Radar.
Guardrails and speed bumps that might contain metal elements should be installed as far
away from the Radar as possible.
 Do not dissemble the Radar.
 Clean the surface of the Radar with a soft dry cloth or a clean soft cloth dipped in neutral
detergent, and then dry the surface.
WARNING

Use accessories suggested by the manufacturer, and install and maintain the Radar by
professionals.
 When using a laser beam device, avoid exposing the device surface to laser beam
radiation.
 Do not provide two or more than two kinds of power supply modes; otherwise, the Radar
might be damaged.
Power Requirements

Improper battery use might result in fire, explosion, or inflammation.
 When replacing battery, make sure that the same model is used.

Use the recommended power cables in the region and use them under the rated
specification.
 Use the power adapter provided with the Radar; otherwise, it might result in people injury
and device damage.
 The power source shall conform to the requirement of the Safety Extra Low Voltage (SELV)
standard, and supply power with rated voltage which conforms to Limited power Source
requirement according to IEC60950-1. Note that the power supply requirement is subject
to the device label.
