SETTING THE BUZZER SUSPENDED PERIOD
An abnormality is indicated again by the buzzer sounding after a certain period has elapsed (the buzzer
recovery time) if the alarm mode continues even after the buzzer has already been silenced by pressing the
buzzer stop key (BUZZER). Always set the “buzzer suspended period” to avoid incorrect recognition of
alarm mode.
 Setting range of buzzer suspended period:
between 10 and 60 minutes in 10-minute intervals (display of setting: between 010
and 060) or no recovery (display of setting; 000)
 Initial setting (factory setting): 30 minutes (display of setting: 030)
The buzzer does not sound again when the setting is 000. The setting should be between 010 and
060 to ensure the safety of stored items.
For example, to change the setting of the buzzer suspended period from 30 minutes (initial setting) to 20
minutes
(The following is only an example. Choose the actual setting according to the desired buzzer suspended
period.)
