When an alarm/error occurs, the factors below may be the cause. Follow the procedure for dealing with each alarm/error as it
arises.
Cautions
• If the fault persists even after the following measures, a device failure is suspected. Contact TERUMO trained service
technicians to request repair.
• Even under the same condition, the alarm timing depends on the alarm sensitivity level.
• Before pressing the Start switch to resume solution delivery after cancelling an alarm condition, ensure that you check the
flow rate and VTBI settings.
Note
• If there is an alarm condition as the power is turned on, the alarm display flashes but the buzzer does not sound.
