General Airline Travel Information
During taxi, take-off, and landing, the eQuinox must be turned
off and stowed under the seat or in another approved stowage
location so as to not block the aisle way or the entry way into therow if the eQuinox will not be used.
During taxi, take-off, and landing, the user must be in a seat
location that does not restrict any other passenger’s access to, or
use of, any required emergency or regular exit, or the aisle(s) inthe passenger compartment of the aircraft if the eQuinox is used.
User’s are not permitted to be seated in an exit row if using theeQuinox.
If the eQuinox is used when decompression of the cabin occurs
and the oxygen cabin oxygen system deploys, then the user is to
discontinue use of the eQuinox and use the aircraft supplemental
oxygen. The eQuinox unit is to be turned off after securing theaircraft supplemental oxygen.
Prior to travel, the user needs to inspect the eQuinox to ensure it
is in good operational condition.

Battery Pack & Airline Travel
Please allow for ground time (preflight checkin, security check in, etc.) and layovers.
Most airlines require that you have an adequate number offully charged batteries to power the device for at least 150% of
the expected maximum trip duration (flight times, all ground
time; before and after flight, and during connections and for
unexpected delays).

It is suggested to always carryan extra battery with you on trips.
Each airline has their own requirements
for traveling with oxygen.
Contact your airline at least 48 hours prior to departure to informthem you will be traveling with the eQuinox.

CAUTION: The US Department of Transportation (DOT) andUnited Nations (UN) Regulations require the removal of
the battery from the device for all international airline
travel when the oxygen concentrator is checked as luggage. Whenshipping the oxygen concentrator, the battery must also be removed
from the device and packaged properly.
