■Reliability of wireless communication

As wireless communication has properties that are different from those of wired communication,

communication errors may occur due to the following.

・Exceeds the communication distance.

・Enters a dead zone.

・Interfered by strong jamming

If signals are often jammed, or being jammed leads to operational problems, stop using the systems and

restart using the systems after removal of the cause.

Radio waves may not be received due to various reasons other than the above. Please understand this

before using the systems.

*A dead zone is an area where the radio wave transmitted from the transmitter becomes extremely weak

due to radio waves reflected from walls or other objects.
