Best Use Tips
When the battery use time begins to encroach on the user’s lifestyle
or impede transport times, it is time to replace the Power Pac battery
pack (BAT3270A). Use these “Best Use Tips” to prolong the life of
your batteries.
1. Always keep the Power Save function On.
2. Use an external power source when possible. For example,
when traveling, use the optional D.C. Auto Lighter Power Adapter
accessory (ADP3204P) to power the ventilator from an automobile
lighter outlet.
3. Always have a backup power source nearby, for example an
extra Power Pac battery pack. When the “Switching to Backup
Battery” alarm is activated you have a minimum of 30 minutes of
the emergency back up battery time left.
4. Keep both the Power Pac and Backup Battery charged up.
Partially discharged batteries will age faster.
NOTE: Remember, the Integrated Battery System is charging
anytime the HT70 is connected to external A.C. or D.C. power.
