2 Important Safety Instructions
2.1 Safety and Precautions
The following general instructions should always be followed in order to assure the proper operation
of Sierra, the safety of operators and the preservation of warranty coverage.
1. The Sierra IFE System has been designed to operate in the pressurized passenger cabin on
the aircraft. Never operate the Sierra IFE System in unpressurized areas of the aircraft Avoid
removing any identification plates, serial numbers or warning labels unless specifically
authorized by the manufacturer.
2. To maximize battery life, the Sierra IFE System has been designed to operate with passive
cooling in temperatures from 0°C to +50°C. To prevent overheating, be sure there is adequate
air flow around the device, and that the heat dissipation holes are not blocked. A minimum
airgap of 1” should be maintained during operation. Please observe all specified dimensions
required for mounting, included in the kit specific Outline Drawing listed in Table 3-1.
3. Sierra has been designed to withstand the mechanical vibrations associated with aircraft
transport, but care should still be taken to provide a stable location and avoid any unnecessary
sliding, shifting, or damage from unsecured cargo.
4. Do not expose Sierra to rain or snow. Care should be taken when transporting to and from the
aircraft.

2.2.1.1 Information to User
Class B Digital Device
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions, may
cause harmful interference to radio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:
-Re-orient or relocate the receiving antenna.
-Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is
connected.
Do not operate the cellular transceiver module:
-Where explosive atmospheres may be present, including refueling points, fuel depots, and
chemical plants.
-Near medical equipment, life support equipment, or any equipment which may be susceptible
to any form of radio interference. In such areas, the cellular transceiver module MUST BE
POWERED OFF. Otherwise, the cellular module can transmit signals that could interfere with
this equipment.
In an aircraft, the cellular transceiver module MUST BE POWERED OFF. Otherwise, the transceiver
module can transmit signals that could interfere with various onboard systems and may be dangerous
to the operation of the aircraft or disrupt the cellular network. Use of a cellular phone in an aircraft is
illegal in some jurisdictions. Failure to observe this instruction may lead to suspension or denial of
cellular telephone services to the offender, or legal action, or both.
