Precautions for Correct Use
Always heed these precautions to prevent faulty operation, malfunction, or adverse affect on the prod-
uct's performance and functionality.
Master Unit
(1) Communications performance may be affected by its environment. Always confirm its operation
before using it.
(2) Install this product at a location where there is an unobstructed view between the wireless push
buttons and the Master Unit. Note that if the wireless push buttons are operated simultaneously, it
may lead to improper reception. Take measures to ensure safe operation of the system in such a
case as well.
(3) When multiple Master Units are used for a single wireless push button, the reception confirmation
LED of the wireless push button lights up either in green or yellow if transmission/reception with
any one Master Unit is successful. Therefore, it may not be possible to determine even if there is a
Master Unit with which transmission/reception has failed only from the display status of the wire-
less push button. Take measures to ensure safe operation of the system in such a case as well.
(4) Do not mount the antenna at a location surrounded by metal, such as inside the panel.
(5) Mount the antenna while ensuring that it is not parallel with the wiring or metal plate. Also, ensure a
safe distance from the wiring and metal plate.
(6) Do not use this product at a location with an extremely high humidity, or near a television or radio,
or an object from which sparks may fly out such as a motor or drill, or even near fluorescent light-
ing.
(7) The Radio Law prohibits connecting an antenna other than that designated. Never change the
antenna.
(8) Do not reverse the power supply connection or connect the product to an AC power supply.
(9) Use the correct power supply voltage.
(10) Do not operate the Setting Switches of the Master Unit while the Wireless Pushbutton Switches
System is in operation.
(11) Always turn OFF the power before replacing the wiring or devices.
(12) Do not handle with wet hands.
(13) Handle this product as industrial waste during disposal.
(14) If communications troubles occur frequently, refer to the Troubleshooting section in the User Man-
ual for details on the actions to take.
(15) After pressing a Slave button, wait for 100 ms before pressing the next Slave button, because the
Master Unit can not receive at the same time signals of multiple Slave buttons.
(16) If you register a Slave button to the Master Unit in an environment where another wireless push-
button switch system is operating around it, it can be erroneously set. Therefore, when registering
a Slave button, perform in an environment where the system of another wireless pushbutton switch
is not operated.
(17) Register Slave buttons to one Master Unit one by one. Be sure to set the other Master Units to the
"RUN mode" or "TEST mode".
