Caution
If the vacuum readings fail these required
minimum levels, remove the delivery device
and perform the same action on the vacuum
tube alone:
• Cover the tube with your finger. The
vacuum gauge should read at least
575 mmHg. Remove your finger. The
vacuum gauge should drop drastically (to
zero or close to zero). If so, the vacuum
unit is functioning properly. Perform the
procedure with a different delivery device
(after performing calibration).
• If the vacuum fails to reach 575 mmHg or
fails to drop to close to zero, the vacuum
unit may require service. Contact customer support.
Note
The recorder screen shuts off after 60 seconds to conserve battery
power. To turn on the recorder screen during a study, press any button.
