*3: ON/OFF settings from EIA-232-D communications without regards to trigger logic switch, turned OFF at '0' and ON at '1'. ON/OFF setting will not be held after turning
the power off.
*4: When operating EIA-232-D Communications and trigger signal input at same time in ON/OFF mode.
When Trigger logic switach is at H : if either controls setting, Light unit will be turned OFF.
When Trigger logic switach is at L : if either controls setting, Light unit will be turned ON.
*5: Defalt setting for trigger logic switch is H ='1(ON)' and L='0(OFF)'.
