This section describes how to turn the LTV
®
Series ventilator on and off, and how to set up the
ventilation modes.
To Turn the Ventilator On
1) Connect the unit to an external source of power. The AC power adapter may be used or the
ventilator may be connected to an external battery.
• The External Power LED is lit to indicate the external power source voltage level.
• The ventilator begins charging the internal battery from the external source.
• The Charge Status LED is lit to indicate the charge progress.
NOTE
In the absence of an external power source, the ventilator automatically begins operation using the
internal battery.
Do not operate the LTV
®
exclusively on the internal battery as a standard operating practice. The internal
battery should be used for emergency situations only or for short periods while switching between
external power supply connections.
REMARQUE
S’il n’y a pas de source d’alimentation externe, le ventilateur s’alimente automatiquement de la pile
interne.
Ne pas utiliser le LTV
®
exclusivement avec la batterie interne en tant que procédure d’exploitation
normale. La batterie interne doit être réservée aux situations d’urgence seulement ou pour de
courtes périodes de temps pendant le transfert entre des sources d’alimentation externes.
