NOTE: Whenever the pulse mode is used, the battery is monitored.
If the SECOND BATT. LED illuminates, either replace the battery or
switch to continuous mode if oxygen supply is adequate. When in
continuous mode, the battery is NOT used.
NOTE: When in the continuous flow mode, the oxygen supply will be
used considerably faster then in the pulse mode. If using a portable
oxygen supply, make plans for an alternative source of oxygen. Replace
the battery as soon as possible.

press the OFF button (FIGURE 3).
10. If turning the system OFF for cylinder replacement or storage,
press the Venture DODD OFF button. Turn OFF the cylinder
post valve, bleed the oxygen from the regulator and turn OFF
the regulator prior to any disassembly.
