SETTING OF ALARM RESUME TIME
The alarm buzzer is silenced by pressing the alarm buzzer stop key (BUZZER) on the control panel
during alarm condition
(The remote alarm is not canceled).
The buzzer will be activated again after certain suspension if the alarm condition is continued (The remote
alarm
continues). The suspension time can be set by following the procedure shown in the table below.
The example in the table is based on the assumption that the desired duration is 20 minutes.
Note: The duration is set in 30 minutes at the factory.
Table Changing procedure for alarm resume time (Ex: change from 30 minutes to 20 minutes)

1 ----
The current chamber temperature is
displayed.
2
Press calibration key
for 5 seconds.
CAL The left digit blinks.
3
Set the figure to F25
with the numerical value shift key
and digit shift key.
When pressed,
the figure of settable digit changes.
The settable digit is shifted.
4 Press enter key. ENT
The current setting is displayed.
The middle digit blinks.
5
Set the figure to 020 with the
numerical value shift key. When pressed,
the figure of settable digit changes.
6 Press enter key. ENT
The setting is memorized and
the current chamber temperature is
displayed.
• The settable alarm resume time are 0, 10, 20, 30, 40, 50, or 60 minutes (The setting is 000, 010, 020,
030, 040, 050 or 060 respectively). The buzzer would not reset if the resume time is set in 000.
• It is recommended to set the alarm resume time when the incubator is not under alarm condition. The
setting during alarm condition is effective on the next alarm condition.
• The setting cannot be changed during power failure.
• The remote alarm during power failure cannot be stopped.
• The set mode returns to the temperature display mode automatically when 90 seconds has passed
without any key operation. In this case, any setting before pressing enter key is not memorized.
Pressing calibration key (CAL) for about 5 seconds leads the calibration mode. In the calibration mode,
the calibration of temperature and CO
2
density is possible. Wrong key operation affects the basic
performance. Never touch any other keys on the control panel in the event of pressing calibration key
(CAL) accidentally. After about 90 seconds, the incubator returns to chamber temperature display mode
automatically.
Operation after power failure
The set value is memorized by nonvolatile memory. Accordingly, the incubator resumes the operation
with setting before power failure.
