Battery Operation
Backup Battery
The internal Backup Battery will provide a minimum of 30 minutes
operation. HT70 will automatically switch to the backup battery
whenever the Power Pac battery pack is removed or when the Power
Pac power is low and the “Switching to Backup Battery” alarm occurs.
Conditions that Affect Battery Use Time
 • PowerSave
 • Pressure
 • RespiratoryRate
Each of the items listed above will affect the amount of time that the
Integrated Battery System will last. The most significant setting that
affects battery use time is the Power Save setting. If this is left OFF, it
will decrease your battery use time by about 30%. When Power Save
is On, the screen will go to sleep (go blank) to save energy. An active
alarm will temporarily end Power Save and the screen will become
active. Power Save will resume two minutes after the alarm condition
is resolved.
Peak pressures and respiratory rate also affect battery use time.
If the peak pressure rises above 30 cmH2O consistently and the
respiratory rate is above 20, you can expect to lose another 15% to
25% of the battery use time.
As the batteries age with use, the time that the HT70 will operate
on battery power from a fully charged state will decrease. Replace
the Power Pac battery pack every 24 months or sooner if battery
operation time is insufficient for your usage.
If the HT70 will be powered from the Power Pac battery pack for an
extended period, ensure that the battery pack is fully charged prior to
use.
NOTE: It is highly recommended to carry an extra, fully charged
Power Pac during transport or outdoor applications.
Check Battery Charge Level
Before using the HT70 for transport or if planning to use the
Integrated Battery System as the primary power source, always
