DEFAULTS<br />

All controls and extended features on the <strong>LTV</strong> ® <strong>1200</strong> ventilator have factory-set default values. When<br />

the operator makes changes to the controls or extended features settings, the ventilator stores the<br />

new settings in non-volatile memory 37 . During POST, the ventilator checks the stored settings. If the<br />

ventilator detects an invalid stored setting, the DEFAULTS alarm occurs and the affected settings are<br />

set to the default values.<br />

When a DEFAULTS alarm is generated:<br />

• An audible alarm is sounded.<br />

• The DEFAULTS message is flashed in the display window.<br />

• All affected controls or features are set to their default values.<br />

To reset the DEFAULTS alarm:<br />

1) Push the Silence Reset button twice.<br />

2) Select and return the control(s) or features to the desired settings.<br />

NOTE<br />

Be sure to check all Controls, Alarms and Extended Features options and return them to the desired<br />

settings.<br />

Repeated occurrences of the DEFAULTS alarm may indicate a problem with the ventilator’s nonvolatile<br />

memory. Please immediately contact a certified Pulmonetic Systems’ service technician.<br />

Control values are re-set to default values each time the ventilator is turned on, only if an invalid<br />

stored setting is detected during POST.<br />

REMARQUE<br />

Assurez-vous de procéder à la vérification de toutes les options de contrôles, d'alarmes et de<br />

caractéristiques étendues, et de les retourner aux réglages souhaités.<br />

L'occurrence répétitive des alarmes PAR DÉFAUT peut indiquer un problème avec la mémoire non<br />

volatile du ventilateur. Veuillez contacter immédiatement un technicien de service certifié de<br />

Pulmonetic Systems.<br />

Les valeurs de contrôle sont rétablies à leurs valeurs par défaut chaque fois que le ventilateur est<br />

allumé, seulement si un paramètre en mémoire non valable est détecté au moment du diagnostic<br />

automatique de mise sous tension.<br />

37 Non-volatile memory is memory that is not erased when the ventilator is turned off or disconnected.<br />
