Terumo CDI 550 Operator's Manual page 45

Note: When an alarm is activated, a visual and/or audible alarm will occur (if the alarm volume is not
set to mute). If the audible alarm for a given parameter is dismissed (the audible tone can be dismissed
by pressing the X button) and a second alarm occurs, or the parameter that caused the alarm falls back
within acceptable range then falls out of the acceptable range, the audible alarm will respond. The default
settings for an alarm is both audible and visual alarms are active.
Note: The CDI System 550 monitor is equipped with the capability to prohibit the user from muting the
audible alarm through the use of a password in accordance with the international standard for alarm sys-
tems in medical electrical equipment.
The password makes the mute option available (crossed-out bell icon has a black background) or not
available (crossed-out bell icon has a grey background). The setting is saved in the CDI System 550
monitor's memory and will remain until it is changed by the responsible person in the user's organization.
When muting is prohibited, the audible alarm can still be temporarily dismissed by pressing the X button
in Operate Mode.
If the password protection feature is desired, contact Terumo Technical Service and instructions (Ref
878829) will be provided upon request. Instructions for the password are provided separately per the
regulation.
If audible alarm muting is desired, it must be done prior to entering the Operate mode.
Note: The alarm settings are automatically stored into memory once the selections are confirmed.
