In case a LED unit fails, other LED units can still properly irradiate light. However, as the total amount of
light is reduced, the curing time should be extended and curing status should be suffi ciently monitored.
The failed LED unit should be promptly repaired.
WARNING
■
Never disassemble or modify the unit. Otherwise, heat generation, ignition, or rupture could be caused.
CAUTION
■
In case the unit fails or damages, stop using the unit immediately, turn off the main switch, and pull out the
power plug.
■
Do not attempt to repair the failed unit by yourself but request an expert to do it after providing an
appropriate indication thereon.
