3.2 Motion Alarm Test
Test the motion alarm to ensure it activates when the platelet agitator motion stops. The alarm may not activate immediately,
depending on the motion alarm delay setting. If the alarm does not activate when it should, refer to Troubleshooting.
Notes
• The motion alarm delay range is 10 - 600 seconds. When testing the alarm, be certain the set delay time has passed.
• Whenthemotionalarmisactivated,theredLEDonthemotionalarmswitchwillash.
• The motion alarm is muted when the alarm volume is turned fully counterclockwise.
Test Motion Alarm
1. EnsuretheAlarmVolumeissettoanaudiblelevelandtheAlarmDelayissettothe
 minimumdelay(asnotedbyredrotationalarrows).
