It is in an installation environment
where radio waves hardly reach. It is installed in a building whose
entire wall is covered with a metal
plate. In operating environments where radio
wave obstacles can not be avoided, con-
sider the communications route from the
ceiling or from the window.
There is a steel shelf between
Master Unit and Slave button, or
it is installed on a floor where
people crowd.
Despite the fact that the Master
Unit is receiving a signal, the red
LED on the Slave button lights
up. Temporary radio wave obstruc-
tion blocked communication
route. In operating environments where radio
wave obstacles can not be avoided, con-
sider the communications route from the
ceiling or from the window.
Equipment that generates noise
intermittently is nearby. Keep the Master Unit and Slave buttons
away from the noise source by about 1
m.
The Master Unit’s power supply is
turned ON again, but it does not
operate normally. The time from turning OFF the
power to turning it ON is short. To turn ON the power again after turning
OFF the power, wait for 30 seconds or
more before turning it ON.
