holder which is fixed on wall or beam.

●

To operate the remote controller at its holder,

●

please ensure that the unit can receive signal

transmitted from the controller at the place

where the holder is to be fixed.The unit will

beep when signal is received from the remote

controller. The signal transmission is weaken

by the fluorescent light. Therefore, during the

installation of the remote control holder, please

switch on the light, even during day time, to

determine the mounting location of the holder.
