FreeStyle™
Portable and mobile RF communications equipment can effect
medical electrical equipment.
Cannula tubing must be non-kinking, which can be used for a
total length of up to 25 ft (7.6 m) maximum.
Ensure the cannula is fully inserted and secure. This ensures
that the FreeStyle unit can properly detect inspiration for oxygen
delivery.
Storing your FreeStyle for extended periods of time at high
temperatures or with a fully charged or completely discharged
battery can degrade its overall battery life.
Depending upon the temperature of the FreeStyle 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.
The FreeStyle battery does not need to be fully discharged
before recharging. It is recommended to charge the FreeStyle
battery after each use.
Charging may take several minutes after connecting the power
to initiate, depending on the battery's internal operating
temperature. This is a normal condition and is intended for safe
battery charging. This circumstance is more likely when the
battery has been fully discharged.
