automatically turned off, and the indicator lamps may also be turned off. In such a case, press the "•" (power
OFF) side of the main power switch and wait at least 45 minutes. After the unit has sufficiently cooled down,
please make confirmation of the attachment state of the lamp and lamp cover, and then turn the power on again.

described in the table below. Please respond in accordance with the instructions within the table. If the same
indication is displayed after the treatment, or if an indication other than the following is displayed, please contact
