Traveling By Air The FAA allows the Inogen One® G2 onboard all U.S. aircraft, here are a few points to make air travel easy. Planning Your Flight When flying with the Inogen One® G2, you must inform the airline that you will be using your Inogen One® G2 onboard the aircraft. You must also keep a signed statement from your physician with you that includes: • Your ability to see/hear alarms and appropriately respond. • When oxygen use is necessary (all or a portion of the trip). • Maximum flow rate corresponding to the pressure in the cabin under normal operating conditions. 16

English

3. The plug should insert into the socket without excessive force and securely remain in place. The Cigarette Lighter Adapter comes with a slide switch pre-adjusted to the narrow position. This will fit most automobile cigarette lighter sockets. If the Cigarette Lighter Adapter is loose in the socket, adjust the switch to the "wide" position. 4. Ensure that the automobile power socket is adequately fused for the Inogen One® G2 power requirements (minimum 15 Amp).

• A new statement will not be necessary each time you fly, but the statement should be available during every flight. • Some airlines may equip their aircraft with onboard electrical power. You may have an opportunity to request a seat with a power port which can be used to power your Inogen One® G2. However, availability varies by airline, type of aircraft and class of service. You should check with your airlines for availability and always plan on having sufficient battery power for the duration of your flight, plus a conservative estimate of unanticipated delays. • Because aircraft use different power port configurations, your Universal Power Supply is equipped for use with two separate DC power adapters – a commonly used cigarette lighter adapter, and a less common four-pin adapter (sold separately). Since it is difficult to determine which type of power supply your aircraft will have, it’s a good idea to keep both adapters available when flying. Before Your Flight Here are some things to keep in mind the day your flight departs: • Ensure your Inogen One® G2 is clean, in good condition and free from damage or other signs of excessive wear or abuse. • Bring enough charged batteries with you to power your Inogen One® G2 for the duration of the flight plus a conservative estimate of unanticipated delays. • Regional/Commuter airlines do not offer onboard electrical power. If your travel plans call for flights on regional airlines, you will need sufficient battery power for the duration of the flight, plus a conservative estimate of unanticipated delays. CAUTION

Airlines may not be equipped to provide backup oxygen.

• Arrive at the airport early. Airport security screening personnel may require extra time to inspect your Inogen One® G2. • While waiting to board your flight, you may be able to conserve battery power by using the Universal Power Supply to power your Inogen One® G2 from an electrical outlet in the airport terminal if available. • You should inform the airline you will be using your Inogen One® G2. Have your physician letter with you and ready for inspection if requested.

Operating Instructions Chapter 3

1. If using airline power port, remove the Battery from the Inogen One® G2 Oxygen Concentrator. Due to aircraft power limitations, the Universal Power Supply cannot be used to charge the Inogen One® G2 Battery when onboard aircraft. 2. Connect the appropriate DC Power Plug for the type of available airline power (see photos on page 7 and 9). Check with airline personnel to ensure compatibility.

• During taxi, takeoff and landing, stow your InogenOne® G2 under the seat in front of you. Your Inogen One® G2 will fit upright under most airline seats. However, if it doesn’t fit you may turn it on its side. • It is not necessary to turn off your Inogen One® G2 during taxi, takeoff and landing if your physician’s written statement requires you receive oxygen during these periods. CAUTION

A change in altitude (for example, from sea level to mountains) may affect total oxygen available to the patient. The Inogen One® G2 has been verified to provide oxygen to specification up to 10,000 ft (3048 m). Consult your physician before traveling to higher or lower altitudes to determine if your flow settings should be changed.

After Your Flight • Remember to recharge additional batteries you may have used prior to your next flight.

Normal Battery Charging To ensure that your battery is properly charging, inspect that the correct AC and DC power output plug adapter is being used and that the adapter is properly inserted into the power outlet. Observe the display or lights that indicate charging status. NOTE
