Note:
• When the operation is started in high ambient temperature, the alarm lamp (ALARM) sometimes flashes,
and then the message (Please check a condenser filter) of the filter alarm is indicated on it in the basic
screen. In this case, the lamp is off automatically when the chamber temperature is getting lower.
• The freezer resumes the operation after power failure with the temperature setting before power failure
as the chamber temperature setting and alarm temperature setting are memorized in the nonvolatile
memory.
• The chamber temperature is displayed for 5 seconds by pressing buzzer stop key (BUZZER) during
power failure alarm. Then the buzzer is silenced. The alarm lamp keeps flashing.
