AirSep Focus Patient Manual page 12

Storing your Focus battery for extended periods of time at high temperatures or with a fully charged/completely
discharged battery can degrade its overall battery life.
Depending upon the temperature of the Focus battery, it can take several minutes for the charging cycle to start after
connecting to power. This is a normal condition and is intended for safe charging. This circumstance is more likely
when the battery has been fully discharged.
The Focus battery does not need to be fully discharged before recharging. It is recommended to charge the Focus
battery after each use.
Cannula tubing must be non-kinking, which can be used for a total length of up to 25 ft. (7.6 m) maximum.
If the Focus power supply remains connected when the battery is fully charged, the four LEDs will turn off within ½
hour.
Ensure the cannula is fully inserted and secure. This ensures that the Focus unit can properly detect inspiration for
oxygen delivery.
When connected to Universal AC/DC power, the unit's battery charges until it reaches full capacity, either while the unit
is operating or turned off.
It may be necessary to initially connect the Universal AC/DC Focus power supply charger to the Focus Battery(s)
before the unit will operate for the first time on battery power. Your Equipment Provider may have already performed
this step for you.
AirSep does not recommend the sterilization of this equipment.
