Note:

The remote alarm is silenced by pressing the buzzer stop key (BZ) as the remote alarm is operated in conjunction with the buzzer, except for the power failure alarm.

When more than two alarm conditions occur simultaneously, the lowest number error code has priority on the error display.

After a power failure, the unit will resume operation with the set value that was in place before power failure occurred.

The over-cooling protection may activate when the set temperature is 2oC. In this case, the chamber temperature will rise to 8oC, but this is not malfunction.
